Can you use 4 cycle motor oil instead of more expensive 2 cycle in your two cycle fuel mix?

I have heard of people doing so over the years, I however would not recommend it. The 4 cycle oil will not burn as clean (it was not formulated to be burned), so there is an enviromental conceren here. Also, because it was never intended to be burned, you will see excessive carbon build up in the head and exhaust passages of your engine. Lastly, I would add the fact that 2 cycle oil is cheaper than an engine overhaul. The other guy pretty much hit it right on, you definatly can but its not good for the engine and it will smoke like crazy. Ace Hardware sells 2 cycle oil quarts for like 5 bucks anyways. 4cycle oil has a lot of additives that are not needed in a 2 stroke. These unburnt chemicals can and will build up on the inside and in the pipe causing obstructions and excessive heat which is detrimental to the operation of the engine. If you do not have oil formulated for a 2 stroke engine, you can use SAE30W which has no added chemicals. If you do use this, you must mix it at twice the recommended mix ratio to get the lubrication that the oil is supposed to provide before it burns off.
