Choosing the Right 2 Stroke Oil for Your Chainsaw

If you want to get the best performance out of your chainsaw, you need to make sure that you buy an oil that meets your unique needs.

Why Use 2 Stroke Oil?

Two-stroke engines have been around for more than a century. Originally used to power motorcycles, you can now find two-stroke engines in a wide variety of appliances, including chainsaws.

Two-stroke engines don’t have many moving parts to worry about, making them an efficient choice for small-scale applications. They also generate less heat than other engine styles, meaning that they’re safer to use.

Unlike the four-stroke counterpart, found in most cars, trucks, and motorcycles, two-stroke engines don’t self-lubricate. You need to mix gasoline with oil before filling your engine to ensure that moving parts don’t stick.

With the wrong type of oil in your tank, you may see your chainsaw smoke, sputter, or even stop working completely. What’s more, you may cause permanent damage to the interior mechanics, particularly the plugs.

Not all two-stroke oils are created equal. Cheap, generic brands may not be able to handle the temperatures generated by a chainsaw. Instead, it’s best to look for high-quality two-stroke oil.

Two-stroke oil is designed to work with air-cooled, high-performance engines. It’s the best choice for peak efficiency, performance, and longevity when it comes to your chainsaw.

It’s important to remember that not all two-stroke oils are created equal. You should check what type of engine you’re dealing with before adding any fuel. Most chainsaws have a non-water-cooled engine that takes standard two-stroke oil. You should only use outboard two-stroke motor oil with a water-cooled engine.

2 Stroke Vs. 4 Stroke

While two-stroke engines are common in appliances such as chainsaws and weed whackers, most of us are more familiar with the four-stroke engines found in vehicles.

A four-stroke engine contains an oil reservoir along with a sump and pump system for circulation. You don’t have to add lubricants to your car’s gasoline, but instead, ensure that you have clean and fresh oil in the pan at all times.

Two-stroke engines are much less complicated, which makes for easier maintenance and repairs. Unfortunately, it also means that this engine style can’t self-lubricate like a four-stroke, as it has no internal oil reservoir.

With a two-stroke engine, you have to mix oil into the fuel supply itself to ensure that everything remains lubricated. This is why you can’t use four-stroke gas with a two-stroke engine.

Four-stroke mixes contain no oil and thus won’t keep moving parts greased. If you use four-stroke fuel with your two-stroke engine, you’ll likely cause lasting damage to the inner workings.

Types of 2 Stroke Oil

There are several different types of two-stroke engine oils to choose from that differ in cleanliness, efficiency, and price point.


Mineral oil, or castor oil, comes from a natural petroleum base and is often the cheapest choice for your chainsaw. Keep in mind, however, that natural oils contain more contaminants and unwanted deposits than synthetic options.

Using mineral oil may leave behind heavy deposits in your chainsaw engine. You may also notice tacky residue that builds on the piston. Over time, all of this debris can build up to slash efficiency and make for difficult maintenance.

Fortunately, you can find mineral oils with minimal additives for a cleaner operation than all-natural options. Some manufacturers will mix in components that improve combustibility and performance at higher temperatures, making them ideal for chainsaw operation.


Full synthetic oil is the most expensive option for two-stroke engines, but it’s also the cleanest. It includes plenty of synthetic additives such as detergents for cleaner running, stabilizers for better efficiency, and octane enhancers to improve fuel rating.

Synthetic oils tend to produce much less smoke and sticky residue than natural mineral oil. It makes maintenance a breeze and may even improve the lifespan of your chainsaw engine. For some, however, the price point can be a deterrent.


Semi-synthetics offer a happy medium between natural mineral oil and full synthetic options. Though it tends to be more expensive than mineral options, semi-synthetics are generally affordable and effective.

While semi-synthetics are petroleum-based, they include plenty of additives for better combustion and improved lubrication. They also burn cleaner than mineral oils, though not quite as clean as full synthetics.

Mixing 2 Stroke Oil

Before fueling up your chainsaw, you have to mix in your chosen two-stroke oil. Always remember to do this in a clean, empty container to prevent contamination. You should also avoid letting pre-mixed fuel sit for longer than a month or so without added stabilizers.

When mixing, fill your container halfway with gasoline. Then, add the full amount of oil and mix well. Finally, pour in the rest of the gasoline. Mixing your fuel in this way will help to prevent waste or potentially harmful splashback. 

Different manufacturers will call for different fuel-to-oil rations, so it’s always important to read the instructions on the label carefully. In general, most chainsaw manufacturers recommend using fuel with a 50:1 gas to oil ratio. Some older models call for a 32:1 ratio.

In Conclusion

Without the right oil on hand, you won’t get the best possible performance out of your chainsaw. You need high-quality 2 stroke oil for the engine if you want power, efficiency, and longevity. Fortunately, there are plenty of options on the market to suit your unique chainsaw.
