I apologize in advance for my lack of understanding on the topic but I've been curious about the following item concerning 2 stroke oil for some time:
I understand that the oil/fuel mix sucked into the crankcase lubricates the crank, various bearings, piston walls etc... My question is whether the oil (or any unburned oil) has any function inside the cylinder. For example does it lubricate the very upper portion of the piston above the rings and or substantially cool the piston head?
If not it seems that the ideal oil (in water cooled engines with a low ash formula) would burn entirely with as little smoke as possible.
So in essence I'm asking if 2 stroke oil contributes anything to the longevity of the engine once it has exited the crankcase?
Merry Christmas Everyone!
