I think we all know that 2 cycle oil is used in 2 cycle engines. What I want to know is do 2 cycle oil companies and auto manufacturers recommend it as a 4 cycle engine fuel additive?quote:Originally posted by Trajan:

Unlike four-cycle engines which have a closed crankcase, these lightweight engines use the crankcase as part of the induction tract, and therefore, oil must be mixed with petrol to be distributed throughout the engine for lubrication. The two-stroke oil is ultimately burned along with the fuel resulting in exhaust emissions with blue smoke and/or a distinctive odor.
The oil-base stock is either petroleum, vegetable, semi-synthetic or synthetic oil and is mixed with petrol/gasoline at a fuel-to-oil ratio ranging from 16:1 to as low as 100:1.
