Can You Use Motor Oil for Chainsaw Bar Oil

Last Updated on July 17, 2023

No, you should not use motor oil for chainsaw bar oil. Doing so can cause damage to the chainsaw and shorten its lifespan.

Using the proper type of oil in a chainsaw is crucial to its performance and longevity. The bar oil lubricates the chainsaw’s chain and bar, while motor oil is designed for use in engines. While it may be tempting to use motor oil in a pinch, it can clog the chainsaw’s oil ports and cause excessive wear on the chain and bar.

Instead, use a high-quality chainsaw bar oil that is designed specifically for this purpose. It will help your chainsaw run smoothly and last longer by reducing friction and preventing corrosion. Taking the time to use the proper oil is well worth the investment in the long run.

Understanding Bar Oil And Its Purpose

Chainsaw bars need specialized lubrication to prevent friction and wear during cutting. This is where chainsaw bar oil comes in, providing a protective film over the bar and chain. Unlike motor oil, bar oil is specifically designed for the demands of chainsaw use.

Motor oil lacks the necessary tackiness and resistance to heat to provide adequate lubrication in high-speed chain operation. In addition, motor oil can interfere with the efficient operation of the automatic oiling system and result in saw performance issues. While bar oil may be more expensive, it is a necessary investment for maintaining chainsaw longevity.

So, resist the temptation to use motor oil – stick to using quality bar oil and your chainsaw will thank you with many years of reliable service.

Risks Of Using Motor Oil For Chainsaw Bar Lubrication

Using motor oil for chainsaw bar lubrication can cause potential risks for chainsaw engines. While motor oil may seem like a quick and easy substitute for chainsaw bar oil, it is not designed for the high rpms and temperatures that chainsaw engines generate.

This can lead to engine damage, decreased performance, and a shorter lifespan for your chainsaw. In addition, using motor oil can cause environmental harm as it is not biodegradable and can potentially contaminate soil and water. To ensure the longevity of your chainsaw and reduce the risk of environmental harm, it is best to stick to recommended chainsaw bar oil for lubrication.

Factors To Consider Before Using Motor Oil For Chainsaw Bar Lubrication

Using motor oil for chainsaw bar lubrication requires careful consideration of factors like weather conditions, cutting material, and the availability of bar oil. It’s important to note that chainsaws require specific lubrication to ensure they run properly and remain durable.

While motor oil may seem like a cheaper and more convenient alternative to bar oil, it may not have the right viscosity or protection against high temperature and friction. In cold weather, it may thicken and cause slow oil flow, while in hot conditions, it may thin out and evaporate quickly.

Additionally, motor oil may not provide proper lubrication for certain types of wood or materials. Therefore, it’s best to use chainsaw-specific bar oil whenever possible, or consult with a professional to determine the best alternative if bar oil is unavailable.

Alternatives To Using Motor Oil For Chainsaw Bar Lubrication

Using motor oil as a substitute for chainsaw bar oil is common. However, it is not recommended as bar oil is specially designed for lubrication while motor oil fails at that. Vegetable oil is an excellent alternative that works as an effective chain lubricant.

It is natural, biodegradable, and considerably cheaper than chainsaw bar oil. Gear oil, easily available and affordable, makes for a good substitute too. It offers excellent lubrication that protects the bar and chain from wear and tear while operating in high temperatures.

While motor oil may seem like a handy substitute, it cannot provide the efficiency and protection that chainsaw bar oil offers. So, transitioning to other affordable and effective alternatives like vegetable oil or gear oil is a better option.


Considering all the facts mentioned in this blog post, it’s clear that using motor oil for chainsaw bar oil might not be the best choice. While motor oil may temporarily lubricate the chainsaw bar, it lacks the tackiness required for the bar and chain.

It can also lead to residue buildup, causing damage to the chainsaw and affecting the longevity of the chain’s life. Therefore, it is important to use the designated chainsaw bar oil for your chainsaw’s maintenance and longevity. By using appropriate chainsaw bar oil, you can improve the performance of your chainsaw, keep it efficient and extend its life.

Ultimately, in order to keep your chainsaw running smoothly and for a longer period of time, it’s worth investing in the right type of oil. Remember, maintaining your chainsaw is important for safety, efficiency and cost savings in the long run.
