Answer 3

Sea Foam

I use it in my cars, motorcycle, and all of my small engines.  Works in 2 cycle engines also so I use it in my weed eater and chain saw.  Works great.

It will keep the whole fuel system in great condition.

It can be found at most major automotive parts stores.  About $5 a can.  Use about 1 ounce per gallon of gas.  In a car add 1 can to a full tank of gas.  Do not re-fill the tank until it is almost empty.
