The larger number represents the amount of gasoline, while the smaller is the amount of oil needed. If you are treating 1 gallon of clean unleaded gasoline, a 50:1 ration translates to 2.5 ounces of two-cycle oil, while preparing a 40:1 blend calls for 3 ounces of oil. It’s best to use the premixed gas within a few days and to shake it well anytime it’s been sitting for a while to redistribute the oil completely into the gas.

Check and replace bar and chain oil regularly to reduce friction, keep the saw from wearing out faster, and to make cutting easier. Be sure to use bar and chain oil, Not regular motor oil. Gas chainsaws use about one tank of bar and chain oil for every tank of fuel, so fill the reservoir every time you fill the tank.
how much oil for chainsaw Related Question:
How much oil do I put in a 2-stroke chainsaw?
Most 2-stroke chainsaws recommend a 50:1 chainsaw oil mix ratio. But some recommend 40:1. Older two-stroke equipment might even call for 32:1.
Can you put too much chain oil in a chainsaw?
If too much oil is being applied to the chain and bar, it could pick up debris more easily, which could make the chainsaw cut less efficiently and also pose a safety risk as the debris is more likely to fly off the chainsaw at any time.
How much oil do I put in my chainsaw gas?
Many gas-powered chainsaws run on a 40:1 mixture of gasoline and 2-cycle engine oil. Other chainsaws run on a 50:1 mixture of gas and 2-cycle engine oil. Some older models use a 30:1 ratio. Check your chainsaw’s manual to be sure.
Can I use 10w30 for chainsaw bar oil?
As a matter of fact, you can actually use regular 10w30 motor oil on a chainsaw as one of the alternatives in case you don’t have bar and chain oil. That’s because 10w30 oil has enough thickness and viscosity that will allow it to withstand the friction that is happening whenever you are using a chainsaw.
What is a 25 to 1 ratio?
25 :1 ratio is 25 fluid ounces of gas per 1 fluid ounce of oil. So divide the total amount of fluid ounces of gas by 25 to find the amount of oil to add. 10 gallons X 128 fluid ounces per gallon = 1280 fluid ounces. 1280 / 25 = 51.2 fluid ounces of oil to add to 10 gallons to achieve 25:1 mixture ratio.
What is the mix ratio for 50 to 1?
For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.
Does 40 to 1 have more oil than 50 to 1?
The 40:1 ratio has more oil compared to gas. That’s why 40:1 oil is slightly denser than 50:1 oil. This higher density helps with the lubrication of the engine. Because of that, the 40:1 ratio has better lubrication of the two.
Why is my chainsaw using so much bar oil?
If there isn’t proper ventilation of the oil tank, a vacuum can occur and reduce the flow of oil to the guide bar. Correctly venting your chainsaws oil tank will allow air into the tank, and avoid a vacuum from occurring. There are a number of factors that contribute to why a chainsaw leaks oil.
Do chainsaws always leak bar oil?
In all but very exceptional cases there is nothing wrong with the chainsaw and what appears to be an oil leak is simply oil that has sprayed from the chain as it rotates at high speed, draining from the saw body and guide bar.
What happens if you don’t use chainsaw without bar oil?
Without lubricant, the speed at which the chain moves over the chainsaw bar can cause some serious friction. A slowed-down chain and excessive fuel burning mean there’s a lot of friction between your bar and chain, which means a lot of heat is being produced that could do major damage to your saw.
What are the most common ratios to mix fuel with oil?
Common gasoline and oil mix ratios are 50:1 and 40:1. Meaning there is 50/40 parts gasoline to one part oil when mixed. The lower the mix ratio number the more oil per volume in the gasoline. To mix properly add oil to your gas can, then add fresh gasoline from the pump.
Can any oil be used for chainsaw bar oil?
Generally, chainsaws can handle a wide range of lubricants. Vegetable and canola oils work well, and automobile motor oil will too, as long as you observe the SAE ratings and use the appropriate oil weight for the season. Always use fresh, never used, oils.
Is chainsaw oil the same as motor oil?
Bar and chain oil is stickier than regular motor oil, so it stays on the chain longer. Motor oil flings off the chain more quickly, so if you try Terry’s tip, be prepared to refill the oil on your chain saw more quickly than with regular bar and chain oil.
Can I use 2 stroke oil for chainsaw?
No, you can’t use any 2-stroke oil in your chainsaw. Some 2-stroke oils are built for motor oils, and this might damage your chainsaw. Also, 2-stroke oils for an air-cooled engine are different from a water-cooled engine.
What weight is bar oil for a chainsaw?
What viscosity is chainsaw bar oil? The viscosity of chainsaw bar oil can vary depending on the formula but 30W is standard. In cold weather, a thin 10W chainsaw oil may be advantageous, while very hot temperatures may require a much thicker 40W or 50W formula.
