yes
All automobiles use 4 cycle engines. 2 cycles are for small moterized bikes or lawn mowers
There is no oil resivoir holding oil that weighs around 1.7 pounds per quart. A 2 cycle engine also does not have valves which a 4 cycle does. All this makes the 2 cycle engine simpliar and lighter.
from my experience with engines mostly small engines such as a chainsaw or a 90cc quad takes 2-cycle oil
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.
Two-cycle lawnmower engines are rare.
none 2 cycle engines run a gas/oil mix for lubrication
For the most part all small engines require 87 octane regular. Some 2 cycle engines require 89 octane gasoline. Refer to your owners manual.
Yes. Any internal combustions needs oil for lubrication. 4 cycle engines have a provision for oil storage in a crankcase. 2 cycle engines require you mix 2 cycle oil with the gasoline.
Yes
None, except price. Synthetic will create less carbon and your spark plugs will last longer. I use synthetic in all my 2 cycle engines.
NO! Don't do that. 2 cycle engines actually burn the oil in the gas, 4 cycle oil is JUST for lubrication, not burning.
Small engines are loud because it would require a large muffler to make them quiet. There is simply not enough room to install a large muffler. This is especially true with 2 cycle engines in trimmers or blowers. The design of a 2 cycle engine contributes to the noise. This and pollution is the reason 2 cycle engines are being phased out in favor of 4 cycle engines.
