Before starting a chainsaw, be sure to top up the bar oil. Bar and chain oil is not the same as two-cycle oil, a type of oil that is mixed with gasoline to lubricate the inner parts of two-stroke gas engines. Instead, bar oil works on the exterior moving parts of the saw, keeping the chain, guide bar, and sprockets properly conditioned to cut efficiently.
With dozens of options available, it can be difficult to sort out which bar oil is right for your chainsaw and working conditions. To help clarify the choices, we have compiled the following list of the best chainsaw bar oil, with detailed product reviews later in the article.

What to Consider When Choosing the Best Chainsaw Bar Oil
A chainsaw is a valuable tool that needs care and maintenance to work properly and keep you safe. Using the best bar and chain oil is one of the easiest ways to prevent breakdowns. Following are some of the important factors to bear in mind as you shop.
Engine Type
Since bar oil works on the exterior parts of the saw, it may not be obvious that the engine type indirectly influences bar oil selection. Lightweight corded and cordless electric chainsaws work well with thinner, lower-viscosity bar and chain oil. Powerful gasoline engines generate more speed, force, and heat, and so these saws work best with high-viscosity, high-tack oils that will not break down under intense conditions.
These generalizations are not intended to be rules. Other factors related to the working conditions and even the oil itself should be considered before choosing the best bar and chain oil for your saw and cutting project.
Formula
The specific formula of the chainsaw oil makes a difference. For nearly a century, petroleum-based bar and chain oils were the only option. This has been problematic because bar oil is released directly into the environment while cutting. In recent years, biodegradable vegetable-based bar oil has shown superior results as an eco-friendly alternative. Unfortunately, the cost of biodegradable bar and chain oil in North America is currently much higher than petroleum.
Petroleum-based chainsaw oil may be either “conventional” or “synthetic.” Conventional oil is refined from crude oil and may be cheaper than synthetic. Synthetic oil is manufactured from modified petroleum products and other additives. Synthetic bar and chain oil is generally considered to be the higher-quality alternative.
Some formula pseudo-indicators on the label are less helpful and can be ignored. Terms like “premium,” “platinum,” and “master” are used for marketing and are not based on industry standards.
Oil Weight and Viscosity
Air temperature affects oil performance. Cold winter temperatures make oil thicker, or more viscous, and difficult to pour into the reservoir. Hot summer weather makes it runny, or less viscous, which increases oil consumption and decreases the oil’s effectiveness. To counteract the effects of air temperature, choose different oil weights for extreme conditions.
- All-season (approximately 10 to 90 degrees Fahrenheit), 30 to 40 weight
- Winter (32 degrees Fahrenheit and colder), 20 weight
- Summer (40 degrees Fahrenheit and warmer), 40 to 50 weight
Tackiness
Chainsaw users often ask if it is OK to use regular motor oil instead of bar oil. After all, motor oil is also designed to lubricate fast-moving metal parts under high temperature and pressure. However, the important difference between bar oil and motor oil is tackiness. Bar oil is made with a “tackifier” additive that makes it stick to the bar and chain at high speeds and temperatures. Motor oil quickly flies off the chain in these conditions, making it far less effective.
Some bar oil brands use terms like “high tack” or “low sling” to indicate the oil’s ability to stay on the bar and chain. It is important to note there is no industry labeling standard to quantify or compare tackiness among products, so these terms can be considered marketing tools.
Additives
Lubricant makers employ a variety of chemical additives to achieve performance results in addition to basic “slippery-ness.” In chainsaw oil, tackifier is one important example. Others may include dispersants, oxidation inhibitors, anti-wear agents, and viscosity improvers. These performance enhancing products add to the price of the oil, so that the old adage that “you get what you pay for” is true.
More expensive branded bar and chain oils contain higher levels of these additives. With consistent use, results may include reduced oil usage, smoother cutting action, and longer saw life.
Some manufacturers add colored dyes to their bar and chain oils. Colored oils can be easier to see inside the oil reservoir, or through the reservoir “window” as an indicator to refill.
Size
Most bar and chain oils are available in quart or gallon containers. The gallon size is the most cost-effective for those who cut lots of wood. Quart bottles may be a more convenient option for occasional users who don’t want to store extra oil for months at a time or longer.

Best Overall
Oregon Chainsaw Bar and Chain Oil
Pros
- Budget-friendly price
- All-season formula
- Extra tacky
Cons
- Thin viscosity is less oil-efficient in hot weather
- More expensive than bargain brands
Oregon Bar And Chain Oil is one of the best-selling bar oils. It is made with additives for increased tackiness compared to other brands and high-film strength to prevent corrosion and wear on the saw chain, bar, and sprockets. Plus this oil reduces buildup of tree sap, gum, and resins on saw parts. This bar oil is suitable for all chainsaw types, as well as pole saws and hedge trimmers.
The specially designed formula works in a wide range of temperatures, with extra tackiness to prevent throw-off. It has a somewhat runny consistency, which is perfect for working in most temperatures. Its lower viscosity allows chainsaw motors to work more efficiently, which may reduce fuel consumption but could also lead to increased bar oil usage.

Best For Summer
Echo 6459007 Power Chainsaw Bar And Chain Oil
Pros
- Its thick viscosity is oil efficient in summer temperatures
- Colored purple for easy oil-level visibility
- Convenient size for frequent use
Cons
- Jug shape makes the oil somewhat difficult to pour into the saw
- Does not pour as easily in cold weather
In hot summer weather, a more viscous bar oil makes chainsaw work easier. Echo chainsaw oil is thick and efficient for summer work, helping you use less oil because it does not get runny in the heat. Additives help the oil stick to the chainsaw bar and chain in difficult work conditions for better protection and smoother cuts through hard, dense, and sappy wood. That means less strenuous work, a lower risk of overheating the saw, and less downtime to refill the bar oil.
Among all-season bar oils, Echo excels in the heat. It may become a bit too thick to easily pour from the jug in extremely cold weather.

FAQs
After reading up on our picks of the best chainsaw oil options, you may have a few questions about using them. Read on to learn more.
Q. What is chainsaw bar oil?
Chainsaw bar oil is a lubricant that protects the saw’s chain, bar, and sprockets from damage while cutting. It differs from engine oil in that it must be both viscous and tacky to withstand high heat caused by friction and adhere to the bar and chain at high speed.
Q. How much bar oil should a chainsaw use?
Bar oil usage varies with differences in the oil makeup and the saw. It is a good practice to top off the bar oil before starting work and during each fuel fill-up.
Q. Can I use motor oil or vegetable oil instead of bar oil?
Bar oil is chemically engineered to protect the saw’s cutting parts. Motor oil and vegetable oil may be tempting to use in a pinch, but they are not as effective. Using other products instead of bar oil may also void equipment warranties.
Q. How often do I need to refill bar oil?
Never run the reservoir dry. Be sure to top off the bar oil at the start of work and each time you stop to fill the fuel tank.
