Winter engine oil: which is better to fill in

How to fill in?

For the stable operation of the snow blower, it is necessary not only to repair and replace parts in time, but also to fill in oil in a timely manner. This procedure consists of a set of rules that are binding. Oil filling steps:

• setting the device on a flat horizontal surface;
• starting the engine for a few minutes to warm up the old fluid;
• turning off the device;
• preparation of a container for waste liquid;
• draining oil through an open hole in the tank;
• closing the drain hole;
• removal of the cap and probe from the neck;
• injection of new oil;
• start the device for a few minutes;
• checking the level of new lubricant.

Oil change must be carried out not only in the engine, but also in the gearbox. Reducer - a part that is located between the movable mechanism and the auger. An oil change should be carried out every 60 hours of operation, as well as at the beginning and end of winter. Manufacturers produce two types of gearboxes:

• serviced - the device can be disassembled for revision;
• maintenance-free - a non-separable device that, in the event of a breakdown, needs to be completely replaced.

Two methods can be used to lubricate the gearbox:

• pouring liquid with a medical syringe into a special hole;
• lubrication of the disassembled mechanism.

The main stages of disassembling the gearbox:

• detaching the casing and drive cable;
• unscrewing the bolts that are located behind the socket for throwing snow;
• removing the auger belt from the pulley;
• dismantling the drive shaft bolts;
• extraction of the screw and impeller;
• unscrewing the middle bolts of the auger;
• dividing the gearbox into two parts.

Selection Guide

Oil for snowplows is presented in stores in assortment. Here are a few examples that have proven themselves in Russian conditions:

1. m-8 m - mineral grease, which is widely used in different countries of the world. Resistant to temperature changes and low wear of the units.
2. mt-16 r is poured into diesel engines. Excellent indicators of wear resistance of details and oxidation of metals.
3. m-82 k - the most common type of mineral lubricant, designed for any engines. The pour point of -30 °C is achieved by using certain additives.

Universal lubricants are very popular today, as they are suitable for most types of engines. Representatives of such manufacturers are well-known domestic and foreign companies:

1. RAVENOL Schneefraese 4-Takt 5W-30 is a well-known German brand that produces lubricants with such advantages as: low volatility and it is possible not to even warm up the engine.
2. Oregon SAE 30 is an American semi-synthetic lubricant used in gasoline snow blowers.
3. Craftsman SAE 5W-30 is a Russian oil suitable for all types of engines and is not inferior in quality to imported counterparts.

One significant drawback of this product is its high price, which is far from suitable for everyone. But, there are less “hardened” brands, their products are practically in no way inferior to the giants. You can select, "Champion", "Interskol".

On a note! You should not buy liquids that arouse suspicion, they are usually sold cheaply and this lure ordinary buyers.

ACEA classification

Divides oils into operating groups similar to API, helping to select the optimal one based on the year of manufacture and engine design features. It has class A / B - universal for gasoline and diesel engines, C for diesel and gasoline engines that meet the latest environmental requirements Euro-4, E - oils for loaded diesel engines of heavy vehicles. In this classification, only some groups can replace others.

In the latest edition of 2012, three categories are distinguished:

ACEA AB - Lubricants for engines powered by gasoline and diesel. It combines all classes A and B developed before 2004, which in earlier editions divided lubricants into two categories by type of fuel. Now there are 4 classes in this category: A1/B1, A3/B3, A3/B4, A5/B5.

ACEA C - lubricants for gasoline and diesel fuel, meet the most stringent modern environmental requirements for the content of substances in the exhaust. Can be used in systems with catalysts and particulate filters, as they have a reduced ash content. There are 4 classes in this category: C1, C2, C3, C4.

ACEA E are lubricants for heavy duty diesel engines and heavy vehicles. The category was introduced at the very beginning of the creation of the class in 1995. In the new edition there are 4 classes: E4, E6, E7, E9.

Rotation and pumpability

The concept of pumpability refers to the ability of the lubricant to pass through the channels under the influence of the oil pump. The term "crankability" refers to the ability of an electric starter to rotate the crankshaft of an engine during start-up.

Since the liquid lubricant loses its viscosity with a decrease in the degree of heating of the environment, the resistance to rotation increases and the supply of the substance to the rubbing surfaces decreases.

For the selection of lubricants, a table with the distribution of temperature ranges according to the SAE standard is used.

For example, the owner plans to fill a 2011 VAZ car with synthetic oil of the 10W-40 standard (according to SAE). The minimum pumpability for this type of lubricant is achieved when cooled to -32°C, but the crankability drops to a minimum value already at -22°C.

SAE 0W-40 grease has improved performance, but due to its increased fluidity, the fluid is not suitable for all power plants. Information on acceptable grades of lubricant is given in the instruction manual or service book (attached to the machine by the manufacturer).

What is the best oil for a high mileage engine

If you carefully study the fuels and lubricants market, then you will notice that there are products on sale with the same specifications, which at the same time differ in viscosity and oil base. In other words, for example, a product with an index of 10W40 can be mineral or semi-synthetic, 5W40 will be a semi-synthetic or hydrocracked oil, etc.

So, the difference in viscosity and the distinctive properties of a particular oil base in many cases allows you to get rid of the problems that are characteristic of worn-out internal combustion engines. As an example, it can be noted that mineral water, which has an SAE index of 15W40, differs in terms of kinematic viscosity when heated to 100 degrees from synthetic analogues of 5W40.

After refueling a used motor with such mineral oil at operating temperatures, a thick lubricating film is created, wear protection improves, oil pressure in the lubrication system increases, and there is less loss of lubricating fluid for waste. As a result, the old motor starts to run quieter and smoother on mineral water than on semi-synthetic oils or synthetics.

However, it should be borne in mind that some ICE manufacturers separately recommend using exclusively synthetic-based lubricants in their motors. It turns out that it is impossible to use a lubricant on a different basis. There have been cases when problems began even after using semi-synthetics in such units, not like mineral water.

We also add that we should not forget about the fact that, with the same operational properties and characteristics, mineral water, semi-synthetics and synthetics differ markedly from each other in terms of antioxidant and thermal-oxidative resistance.

This means that mineral oil oxidizes faster than others and loses its properties, that is, it simply ages. If we add to this a certain “fatigue” of the engine itself and its systems (leakage of nozzles, coking, etc.), the aging of the lubricant will occur even faster.

For this reason, it is separately taken into account that if a transition was made from semi-synthetics or synthetics to a mineral base, then it is necessary to further reduce the oil change interval. In simple words, you need to know when it is better to change the oil in the engine, depending on its type, properties and other factors. It is also necessary to correctly perform the replacement itself.

Can you use a car?

If it is not possible to purchase a special engine oil for a snow blower, experts recommend using an automotive fluid that has the following markings:

• 0W - for temperatures not exceeding 30 degrees below zero;
• 5W - for temperatures not exceeding 25 degrees below zero;
• 10W - for temperatures not exceeding 20 degrees below zero;
• 15W - for temperatures not exceeding 15 degrees below zero;
• 20 W - for temperatures not exceeding 10 degrees below zero.

Also, the types of engines must necessarily match - both the snow blower and the car. It is strictly forbidden to use summer car oil in winter. At the first opportunity, experts recommend that you definitely replace the car oil in the snow blower with a specialized lubricant.

Choice

What kind of oil to fill in a snow blower so that it works properly? Not many people know that the choice of oil should be based on the engine and its performance. Diesel engines of naturally aspirated snowplows usually use M8g2k and M8DM winter oils.

The latter is good to use for turbocharged diesel engines.

Motor 1D12VMS 1

Many machines are equipped with 1D12BMC1 motors, in which the use of low viscosity oils is contraindicated. In order to lubricate these types of engines, it is necessary to use M-14G2k, in rare cases MT-16p. Cold start with M-14G2k and MT-16p can only be applied if the window is no more than five degrees outside.

If the snowplow has been standing for a long time in the cold or stored outside, then it must be warmed up before starting. During the summer storage of the snow blower, care must be taken to protect the motor from corrosion.

For this purpose, often take used oil - its conservation characteristics are much higher than that of what is placed in a barrel.

When choosing oil for a diesel engine, one of the main values ​​​​is its brand:

• Motor brand: D-242; oil for it: M-8G2k. Not at all like the M-8G2 and M-10G2. It differs from them in effective additive compositions, which provide the opportunity to increase the time required to change the oil. M-8G2k are successfully used in cars of domestic brands.
• Engine brand: YaMZ-236M2-4; oil for it: M-8G2k, M-8DM. M-8G2k differs from M-8G2 and M-10G2 types in more effective additive compositions, while it is possible to increase the period indicated for oil change. M-8G2k and M-10G2k are used in KamAZ, ZIL, Ikarus.
• M-8DM. It contains a mixture of distillate and residual components that are produced from sour crude oil and new composite additives that improve properties that fight against corrosion and wear of parts. M-8DM is used during winter or summer operation of highly accelerated turbocharged diesel engines

Oil M-8DM

Can be used on naturally aspirated diesel engines where the oil does not need to be changed often.

It is poured, both in domestic and foreign equipment:

• Motor brand: 1D12BMC1; oil for it: MT-16p, M-14G2k.
• MT-16p oil - used to lubricate naturally aspirated engine diesel engines. Certified in Russia. The oil has the following properties: detergent, antioxidant, anti-corrosion and anti-wear.
• M-14G2k. The composition with G2k oil is identical. Scope of M-14G2k:

It is used for transport diesel engines of four-stroke type.

Can be used instead of M -10 G2k oil during summer operation of diesel engines, in regions where summer is long and very hot:

• Motor brand: Y-2D6-TK-C5; oil for it: MT-16p, M-14G2k.
• Motor brand: YaMZ-238BE; engine oil: M-8DM.
• Motor type: YaMZ-238M2; oil for it: M-8G2k, M-8DM.
• Motor type: YaMZ-238M2-1; oil for it: M-8G2k, M-8DM.
• Motor type: KAMAZ-740.55-360; oil for it: M-8DM.
• Motor type: YaMZ-7511; oil for it: M-8DM.

You can also choose Revenol engine oil, which is used for 4-stroke snowplow engines. Top selling oils: Ravenol Schnefrase 4T SAE OW-30 Wollsink and Ravenol M 4T SAE 5W-30 Sinf. The latter belongs to the type of synthetic motor oils of the highest quality.

Ravenol M 4T

See the video for more details:

The oil has a light green color and can be used for small-sized 4-stroke equipment that is operated in the winter months. The oil prevents wear during high production and protects the entire machine from rust.

During its use, the technique consumes less hot. This happens due to the reduction of emissions of harmful substances into the environment.

Ravenol m 4T SAE 5W-30 Sinf provides an uninterrupted start in February frosts at temperatures up to -30 ° C, Ravenol Schnefrase 4T SAE OW-30 Wollsink - up to -50 ° C.

The use of these engine oils reliably protects the engine during operation in extreme conditions, protecting the device under heavy load at maximum engine performance.

Husqvarna snowblower oil is ideal for snowblowers of the same name.

One of the main characteristics of a small is its viscosity.

The degree of viscosity should correspond to the air temperature. If the temperature is from zero to eighteen degrees, use SAE 5W-30 type oil, if the temperature is below eighteen degrees, use SAE 0W-30.

Husqvarna snow blower oil change

Properly selected oil plays an important role in the maintenance of snowblowers. The correct operation of all engine parts and other structural components depends on the composition. As practice shows, when choosing an oil, you should pay attention to the following factors:

• Freezing point - the lower it is, the better;
• Density - indicates the amount of additives, the denser the oil, the longer it will last;
• Brand - it is better to buy lubricants only from the most famous and trusted brands.

As a rule, Husqvarna snowplows do not require frequent oil changes. However, in order to avoid breakage and abrasion of elements, it is better not to ignore the need to replace the lubricant. To replace, you will need to unscrew the filler cap in the crankcase, and then drain the old oil. Next, the drain plug is inserted into place, and a new composition is poured into the tank.

Results of experiments with oils

Specialists of the well-known automotive magazine "Behind the Wheel" conducted a six-month study of several types of synthetic oils under the conditions of operation of cars in city traffic jams (at idle). To do this, the engines worked for 120 hours (analogous to a run of 10 thousand kilometers along the highway) at 800 rpm without cooling. As a result, interesting facts were obtained ...

First, the viscosity of all engine oils during prolonged idling up to a certain (critical) moment is significantly less than when driving “on the highway”. This is due to the fact that at idle there is a passage of exhaust gases and unburned fuel into the engine crankcase, where it all mixes with oil. In this case, some (insignificant) amount of oil may be in the fuel.

The value of the drop in viscosity of engine oil is about 0.4 ... 0.6 cSt (centistokes). This value is within 5…6% of the average level. That is, the viscosity is within the normal range. However, this only happens up to a certain point.

Clean and used engine oils

Approximately at 70 ... 100 hours (each oil is different, but the trend is the same for all), the viscosity begins to increase sharply. And much faster than when working in the “track” mode. The reasons for this are as follows. The oil is constantly in contact with the products of incomplete combustion (as described above), and reaches its critical saturation. The mentioned products have a certain acidity, which is transferred to the oil. Also affected by the lack of ventilation and low turbulence of the air-fuel mixture due to the fact that the piston moves relatively slowly. Because of this, the fuel combustion rate is below average, and the ingress of exhaust gases into the crankcase is maximum.

The widespread opinion that a large amount of dirt is formed in the engine during idling has not been experimentally confirmed. However, the amount of high-temperature deposits was small, while the amount of low-temperature deposits was large.

As for the wear products, their amount is much greater for the oil operated in the “plug” mode than for the one that was on the “highway”. The reason for this is the low speed of the pistons, as well as the high operating temperature of the oil (lack of ventilation). As for waste, each oil behaves differently. However, it can be argued that due to high operating temperatures and an increase in density, waste will also increase.

Based on the information provided, we will try to systematize the data and answer the question of how many kilometers to change the oil in the engine.

Types of oils and their features

Oils are divided into three types:

• synthetic;
• semi-synthetic;
• mineral.

Mineral oils are a product of petroleum distillation. Due to the fact that they contain sulfur, these oils increase the oxidizing properties of the metal. Therefore, the final composition of sulfur should be no more than 1 percent. Various additives are added to increase useful qualities. The cost of such oils is the lowest.

Synthetic oils are obtained by synthesizing various substances, initially have protective properties, are characterized by lower consumption and resistance to extreme loads and temperatures. Due to the costly production, the output is a high price tag. However, the quality of these oils is much higher.

Semi-synthetic - an intermediate link that is obtained by mixing mineral oils and synthetic oils in a ratio of 70 to 30. They have better characteristics and properties than mineral oils, but are inferior to synthetics. Accordingly, the price tag here is average.

The table below shows the recommended types of lubricants for various engines, as well as their characteristics and cost.

In addition, there are universal lubricants for all types of engines.

1. RAVENOL Schneefraese 4-Takt 5W-30 is a synthetic four-stroke oil. The low evaporation rate ensures low consumption. Protects against corrosion, wear, carbon deposits. It has high resistance to oxidation. It can be used in conditions of "cold start", that is, it quickly and efficiently lubricates all parts of the mechanism in conditions of cold temperature and an unheated engine. The price for 1 liter is 550 rubles. Production - Germany.
2. Oregon SAE 30 is a semi-synthetic gasoline engine oil with high cleaning properties and low consumption. Production - USA. The price for 1 liter is 420 rubles.
3. MTD SAE 5W-30 is a 4-stroke mineral oil. Provides a "cold start", well protects against wear and corrosion. Features low consumption. Production Germany. The price per liter is 600 rubles.
4. Craftsman SAE 5W-30 is a mineral oil for gasoline and diesel engines. Provides a "cold start", reduces noise during operation, provides fuel economy, protects against corrosion and wear. Production - Russia. The price for 1 liter is 390 rubles.

Lubrication types

Now every major manufacturer that makes snowplows basically produces their own engine oil for snowplows. Its use is recommended, but basically everyone is simply obliged to pour liquid from their production, ostensibly in order not to void the warranty in the event of an engine breakdown. Basically, 3 types of liquid are widely used: mineral, synthetic and semi-synthetic.

Chainsaw oil - how to prepare a fuel mixture. What oil to use to lubricate the chain The correct ratio ...

Mineral - the cheapest product, which is a direct distillation of oil. In such liquids there is a large percentage of sulfur, which increases the process of metal oxidation. Therefore, you need to carefully look at the packaging and choose a product with a sulfur percentage of no more than 1%. To improve the quality indicators, all sorts of additives are usually added to it.

Synthetic - the main drawback of this liquid is the price. The product is synthesized by combining substances that initially have high strength and resistance to temperature fluctuations. Such a lubricating fluid has half the consumption, unlike mineral.

Semi-synthetic - this fluid combines 2 components from mineral and synthetic lubricants. Components in the composition of 70% mineral and 30% synthetic materials. These oils are popular. The price of lubricant is more than mineral, but less than synthetic.

Two-stroke and four-stroke engines

Internal combustion engines are divided into two types:

• two-stroke;
• four-stroke.

One stroke is the movement of the piston up or down. For one revolution of the shaft, two cycles are required. Engines in which one revolution of the shaft occurs per operating cycle are called two-stroke. Models with two revolutions are four-stroke. The differences between these engines are not only in design, but also in some other indicators. In particular, there is a difference in the method of lubrication.

In a two-stroke engine, lubrication is carried out using a mixture that is obtained by combining oil and gasoline in a ratio of 1:25 or 1:50. The mixture circulates in the system and lubricates all the necessary components. After its ignition, the oil is eliminated in the form of combustion products. There are two ways to get a mixture. In the first case, this is carried out directly by the operator, that is, a ready-made version is poured. In the second technique does everything itself. In this case, the engine is equipped with a special oil tank, from which, using a pump, oil in a strictly specified amount enters the nozzle where mixing is carried out.

4-stroke engines don't need a mixture. Oil and fuel enter the system separately. In this case, the engine has a special lubrication system, which includes a pump, filters, a valve and an oil supply line.

Oil Requirements

Since the equipment will work in a harsh, winter climate, any mechanical unit does not like an abundance of water and needs high-quality consumables. When choosing, the following requirements are imposed:

1. The ability to use one type of oil for any engine, more precisely, its versatility.
2. fluid life. None of the potential users of winter equipment is interested in a quick oil change on a snow blower, everyone is interested in doing this as rarely as possible.
3. High-quality oil has a high degree of lubrication of rubbing mechanisms, the wear of parts and their further work directly depend on this.
4. Energy saving is also far from the last indicator on this list. The better the oil, the higher its energy saving and minimum heat loss.

When choosing a liquid that is poured into a snow blower, you need to find out what type of engine is on the unit. Two types of motors are commonly used: two-stroke and four-stroke. Each of them has its own characteristics.

In a two-stroke engine, for operation, it is necessary to fill in gasoline mixed with oil in the recommended proportions. Then the pump pumps the mixture from the tank into a special tube and further into the cylinder. Suitable oils in such a motor are oils that, when burned, will leave a minimum amount of soot.

In a four-stroke engine, a special system has been invented that allows you not to mix oil with gasoline. A four-stroke invention is considered more economical than a two-stroke one. It consists of a filter, line pump and valve. Here, the oil has a slightly different function. They consist in the stable preservation of the performance of the motor throughout the entire service life of the mechanism. Different engine designs have given rise to a different choice of oils for them.

Snow blower gear oil - how to change it yourself?

The gearbox is another mechanism that needs timely oil changes. As with a snow blower engine, the correct operation of the gearbox is highly dependent on the right lubricant. There are two types of oils that are suitable for snowplow gearboxes - thick and thin oils.

Determining which lubricant is suitable for a snow blower gearbox is quite simple. If an oiler is provided in the mechanism, then the gearbox must be lubricated with a thick composition. If there is no oiler, but there is a filler bolt, then only liquid lubricant should be poured into the gearbox.

The algorithm for changing the oil is as follows:

1. Set the snow blower to a stationary position;
2. Unhook the protective cover made of plastic, which prevents damage to the belts, and then remove the auger drive cable;
3. Then unscrew the screws that are behind the snail from which the snow masses are ejected;
4. Remove the auger drive belt from the snow blower pulley;
5. Loosen the screws holding the auger shaft;
6. Move the snow blower snail to its natural position and pull out the auger mechanism along with the impeller;
7. Remove the shear bolts that secure the auger to the shaft and disassemble the auger;
8. Disassemble the gearbox into two parts. To do this, clamp the part of the shaft on which the gearbox is located in a vice in a stationary position. After that, unscrew the 6 bolts holding the two parts of the mechanism together. Then, using a hammer, disconnect one part of the gearbox from the other;
9. After disassembling the gearbox, it is necessary to thoroughly rinse its elements from the remnants of the old lubricant. To do this, it is best to place them in a container of gasoline and wait for about 30 minutes;
10. Next, unscrew the fitting, clean it from the remnants of dirt and fill it with new grease;
11. Then screw the fitting back and assemble the gearbox in reverse order.

Operating tips

It is important to use the equipment regularly and maintain it on time. It is best to remove freshly fallen snow, not in large volumes. If the cover is already deep, but recently formed, then it is necessary to work with the unit slowly. With packed snow, movements should be even slower, no more than 30 cm at a time. This will reduce the load on the gearbox. Do not forget about safety measures, you need to wear non-slip shoes and work in good visibility.

In order to make life easier for yourself in the winter and purchase a quality snow blower, you must immediately determine what price suits you, how much it will work, whether you need to pay for a brand or buy a Chinese clone. You should not take a very cheap one, made somewhere in the basement, which costs a penny and will fall apart very soon. But it's also stupid to pay for the name of a well-known company. You need to choose the golden mean.
