The grade and viscosity of the oil
Any 4 cycle or automobile oil of the correct weight.
The terms 4 stroke, and 4 cycle, have the same meaning. There is no difference in the oil.
Yes, if it is a 4 cycle boat engine. However if the engine is a 2 cycle engine you cannot use automobile 4 cycle oil and must use 2 cycle engine oil.
The 2 cycle oil will be marked 2 cycle and have a mixture rating like 25 to 1 mix on the label The Four cycle oil will have a weigh or viscosity rating, 10W30 or W30 weight oil.
No difference. Automobile motor oil is 4 stroke oil just like the oil you use in a 4 stroke ATV. Just purchase the correct weight of any name brand. I recommend you use 100% Synthetic in any air cooled engine.
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.
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.
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.
