Best Bar and Chain Oil Brands

Every small engine needs some kind of lubricant to run well. Without the right oil the engine will overheat, which will eventually lead to significant damage. Bar and chain oil possesses the right viscosity for small engines like chainsaws, and will ensure the machines work well. 

The best bar and chain oil brand is STP Tools and Chainsaw Oil Treatment. This brand has received excellent reviews and comes at an affordable price. STP Oil works well in electric, gas, and battery-powered chainsaws. 

This article will show you what factors to consider when choosing a bar and chain oil, why you need this type of oil, and the quality aspects of different oil brands.

What Causes a Chainsaw To Seize?

What Is Bar and Chain Oil?

Bar and chain oil is used to lubricate the working parts of a chainsaw. The liquid reduces friction that can lead to engine damage over time. Bar and chain oil is also thicker than regular motor oil, so you can’t use ordinary motor oil in a chainsaw. 

In the winter, a thick and viscous bar and chain oil can help combat the cold. A thicker oil will help to cut down on the dust released by the saw and prevent the saw from gumming up when cutting sappy trees.

Conversely, you can use a thinner oil in summer as the weather is warm and you don’t need as much lubrication. The temperature affects the oil’s viscosity and ability to work on the saw, so it’s best to use the right kind according to the climate you’re operating in.

Here’s a YouTube video to give you a better understanding of bar and chain oil:

It’s Not The Same As Regular Motor Oil

Don’t mistake bar and chain oil for ordinary motor oil and pour it into your chainsaw. Bar and chain oil has a more sticky consistency that stays on the chain longer than standard motor oil. You can use regular motor oil if you’re in a tough spot, but avoid it as much as possible when lubricating your chainsaw. 

Which Bar and Chain Oil To Buy

With so many brands on the market, finding the best bar and chain oil can be a challenge. It’s best to look at the factors that distinguish some brands from others as this can help you choose the oil that works best for your small engine.
