Things To Consider Before Buying Two-stroke Oil For Your Snowmobile

Isn’t it really tough to choose the right kind of engine oil for your snowmobile?

The two-stroke engines are available in plenty in the markets for their particular configured snowmobile engine. Due to a lot of options available in the market, the task has become even more complicated than before.

Firstly, it is important to understand your engine’s need and requirements then go to the specifications as each and every engine is unique in its own way. As you go further in the article you will get an idea about the two-stroke oil used in the two-stroke engines of snowmobile, their types and also about the best two-stroke oils available in the market.

What is two-stroke oil?

What is two-stroke oil?

The two-stroke oil also known as two-cycle oil or 2-T oil is a distinctive type of motor oil which is used in the “crankcase compression two-stroke engines”. The two-stroke engine is exceptional to the four-stroke engine.

The two-stroke engine uses the crankcase as a part of the induction tract, unlike the four-stroke engine whose crankcase is closed except for its ventilation system. Hence, the two-stroke engine oils are mixed with gasoline in order to distribute the oil all the way through the engine to provide proper lubrication.

This mixture of oil with gasoline is termed as “petroil” or “premix”. The oil burns along with the fuel while combustion as a “total-loss oiling system”. This helps to increase exhaust emissions with excess smoke or a distinctive odor.

The two-stroke oil has much lower ash content in comparison to the regular lubricating oil so as to minimize the deposits which form due to the presence of ash in oil during combustion in the combustion chamber.

Types of two-stroke oils

As you have got an idea about the difference between a two-stroke oil and a four-stroke oil, let us now move ahead and understand the different types of two-stroke oils.

There are basically three main types of two-stroke oils;


Conventional oils

These oils are extracted from the crude oil through a complicated process of filtration and cleaning to remove the various contaminants in the oil. Unlike their synthetic counterparts, the petroleum-based oils are cheaper in rates. They provide an all-round performance along with the best rust protection.

They do not burn as cleanly as their synthetic counterparts and also they lack the “film strength” vitals required for resisting heavy loads and high temperatures. Thus, this makes them ideal for snowmobiles as they are least expected to separate at such low temperatures.

They are widely used for “low-performance engines” and “constant RPM 2-cycle engines”.

Castor oils

The castor oil is all-natural oil and fairly similar to other vegetables- derived oils. It is generally used in high-performance engines where the contact pressure is very high especially at high RPM. The chemical compositions of these oils allow them to polymerize when exposed to a high temperature which results in the formation of a sticky “wax”.

The wax thus formed has superior lubricating properties that can separate the metal surfaces although for a short time during oil starvation period to prevent them from squeezing out when pressed in between the two surfaces.

The castor oil has an exceptional “wetting” ability which helps it to spread out over an entire surface with ease. However, the presence of gum in castor beans results in a drawback.

The gum prevents the oil from burning well thus leaving a maudlin residue over the cylinders and pistons of the machine. Nowadays, the modern castor oils have a much less amount of gum in them still you need to consider this before buying castor oil for your two-stroke engines.


The synthetic oils are made up of different organic and synthetic compounds. They burn remarkably clean and provide superior surface-wetting properties. They are highly soluble in methanol and gasoline, unlike the castor oils. They can proficiently transfer heat and don’t depreciate with time.

While the process of combustion, they never leave depositions like other two-stroke oils thus prevents you from wasting your time from scraping off carbon deposits from the engines. They perform remarkably than petroleum-based two-stroke oils at high temperatures and high loads.

Things to consider before buying two-stroke oil for your snowmobile

two stroke engine oil

The market provides us various types of options with different qualities and features of two-stroke oil making the decision more and more complicated and confusing. The task can be eased out if we know the things we need to consider before buying two-stroke oil for the snowmobile.

Before buying two-stroke engine oil, it is very important for the owner to understand their engine as each and every engine has its own requirements and needs.


The oil in the engine prevents the metal to metal interaction by providing a “field cushion”. This, in turn, prevents the wearing down of the engines and helps in smooth functioning. The engine oil has additives in it to prevent rusting which is vital during the off-season.

The two-stroke snowmobile engines are designed sophistically with variable exhaust valves which are highly unique than the two-stroke engines of motorcycle, etc. because of its use during low-temperature weathers.

The snowmobile manufacturers are highly specific about the type of two-stroke engine oil and lubricant requirements to be used for their designed two-stroke engine. Thus, many manufacturers sell their own brand of oils that is specific to their engine.

High performance

The synthetic oils have been in trend among the racers as it provides high performance and is also cost-effective. They can easily mix with gasoline and methanol providing a clean burn and superior wetting properties unlike the other two types of two-stroke oils.

The synthetic oils do not leave back residue of carbon as the castor or petroleum-based oils.

They are smokeless as well as odorless. They also have low ash content and low pour value with the capability to keep all the valves clean. This makes them the highly preferred two-stroke engine oil for snowmobiles.

Weather in which it is used

The two-stroke engine oils are available for motorcycle, lawnmowers, etc. but it is always suggested that these two-stroke engine oils should never be used in snowmobile two-stroke engines due to the difference in the pour point values.

The lowest temperature at which a fluid moves as a result of gravity is called its pour point value. This is an essential aspect while choosing two-stroke engine oil as it gives an idea about the oil’s low-temperature start-up.

The two-stroke engine oils for snowmobiles are designed specifically with a deep-freeze pour point value which is generally tolerated by a snowmobile. Generally the oils made specifically for the two-stroke snowmobile engines contain elements that are statistically measured to have a pour point value of minus forty-degree centigrade.

Cost of the product

In addition to all these points, it’s important for you to research all kinds of products and understand their specifications and your requirements. As you have already spent a lot of money on buying a snowmobile, it is advisable to consider buying engine oil worth the value rather than a cheap one which may destroy your engine eventually your snowmobile.
