20w/50 is what comes with the 4-cycle string trimmer. While Home Depot is the sole distributor of Ryobi tools, they do not have the oil in Montgomery, AL
NO! Don't do that. 2 cycle engines actually burn the oil in the gas, 4 cycle oil is JUST for lubrication, not burning.
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
The grade and viscosity of the oil
Use 4 cycle oil if the engine is a 4 cycle engine. Use 2 cycle if it is a 2 cycle. Use the weight oil recommended by the manufacture of your ATV.
if you have to mix oil with the gas its 2 stroke or cycle and if you have to change the oil its a 4 stroke or cycle
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
Any 4 cycle or automobile oil of the correct weight.
If the engine has an oil sump and an oil filler spout, it is a 4-cycle engine. On a 2-cycle engine, oil must be added to the fuel.
You can not use 4-cycle oil in a 2-cycle engine because the four cycle oil will not mix it is not designed to.Two cycle oil is designed to mix with fule to lube the two cycle parts in your motor.
No. In this case, stroke and cycle means the same thing. So 2-stroke/2-cycle engines should have 2-stroke/2-cycle oil and 4-stroke/4-cycle engines should have 4-stroke/4-cycle oil.
I don't know the science behind their chemistries, but personally I would not use 2 cycle oil in a 4 cycle engine. 4 cycle oil is cheap enough, use the right stuff.
NO!2-cycle fuel has the oil added to it. In a 4-cycle engine, the oil is separate. If you use 2 cycle fuel in a 4 cycle engine it would be like dumping 10w-30 oil into the fuel tank of your car along with the gasoline - NOT A GOOD IDEA!NO, NO, NO!!!!!!!!! Use only 4 cycle oil in a 4 cycle and 2 cycle mixed with the fuel in a 2 cycle. Why would you even consider doing this?
