Blended gas and oil used in RYOBI chainsaws

The operator of a chainsaw powered by a 2-cycle engine must blend gas and oil before refueling the device. Not only would the engine’s performance suffer, but the improper fuel might also destroy it.

RYOBI 2-cycle chainsaws need a 50:1 mixture of gasoline with an octane value of at least 87 and premium 2-cycle engine oil. Do not fill up with gas that has more than 10% ethanol in it.

Blend the gasoline and oil in an area with plenty of airflow. Wear goggles to prevent eye damage. Wait a few minutes for the engine to cool before taking off the gas cap. If the product’s manual suggests extra precautions, follow them.

Damage Done to a RYOBI Chainsaw by Stale Gasoline

When a RYOBI chainsaw stops working, old gas is usually the blame. It might be the root cause of a chainsaw’s demise, poor performance, or inability to start.

This is due to the fact that gas might lose some of its effectiveness as early as 30 days after purchasing.

Ethanol, which is included in most modern gasoline, is a moisture magnet. After a while, the water and ethanol will separate from the gas, leaving behind varnish and sticky deposits that clog fuel filters and deteriorate machinery.

To get the most out of your RYOBI chainsaw, use gas with no more than 10% ethanol instead of the recommended ethanol-free gasoline. Small engines, like the one in your chainsaw, may be severely damaged by ethanol.

How to Fill a RYOBI Chainsaw’s Gas Tank with Gas and Oil

Two-cycle RYOBI chainsaw engines call for a 50:1 gas-to-oil ratio. This indicates your engine requires a mixture of 50 parts gasoline and 1 part 2-cycle engine oil.

You may ruin your chainsaw’s motor by putting the incorrect kind of gas in it. You should never run a RYOBI 2-cycle engine on unleaded petrol. Gasoline provides little lubrication and causes engines to run exceedingly dry.

Using the wrong sort or quantity of 2-cycle engine oil or using straight gas might cause the engine to seize. There’s a good probability you destroyed the engine and it won’t start up again if this occurs.

Fuel with an octane value of 87 or higher and no more than 10% ethanol is recommended. You should only use midgrade or premium gas in your chainsaw.

Never put into your vehicle fuel with an ethanol percentage more than 10%. Ethanol content may range from 15% to 85% in the fuels labeled as E15, E30, and E85.

2-Cycle Oil for RYOBI Chainsaws

RYOBI recommends 2-cycle engines use oil compliant with ISO-L-EGD and JASO M345 FD. Other motor oils are nothing like this one.

To get started on your 2-cycle mix, use the following chart to determine how much oil and gas you’ll need. For instance, to produce 1 gallon of fuel mix, combine 1 gallon of petrol with 2.6 ounces of 2-cycle engine oil.

Prior to adding to the tank, mix in a gas can.

Instructions for filling a two-cycle RYOBI chainsaw with gas:

  • Take the top off a legal gas container. Fill a gas can with unleaded gasoline (at least 89 octane and no more than 10% ethanol).
  • Add the 2-cycle oil to the gas can according to the chart’s recommended ounces.
  • Put the cap back on.
  • The gasoline and oil should be gently shaken together to combine them.
  • Put some into the gas tank of the chainsaw.

Preheat-Mixed-Fuel 2-Cycle

RYOBI sells gasoline that has already been blended and does not include any ethanol. This gasoline may be put straight into the fuel tank. Nothing needs to be weighed or measured since there is no need to do so.

In addition to this, it does not include any ethanol, which means that you will not have to be concerned about any of the negative effects that are related with the use of that drug.

Add fuel stabilizer to RYOBI chainsaw gas.

You should apply a fuel additive if you won’t be able to burn through the fuel before it deteriorates. Some seasons are better than others for chainsaw usage around here. This is why I put a fuel stabilizer into my gas tank every time.

Fuel additives are often found in 2-cycle engine oils. But they’re certainly not all the same. Products vary in the length of time they claim to keep the gas stable for, with some promising up to 30 days and others promising up to 2 years.

I like that gasoline additives like Sea Foam Motor Treatment and STA-BIL can maintain fuel quality, reduce moisture content, and clean the fuel system.

New fuel needs to have fuel additives added to it. It can’t fix the problems caused by old fuel.
