Please help me out...what is the difference, and how does it differ from a "high ash" oil? An oil industry representative recommended this oil. No, he did not work for Shell. He said it would be very compatible with 100LL.
Low "ash" oil leave less deposit in the cylinder when it burns. On 2-cycle engines, you want to mix a low ash oil to help lubricate and not create deposits. Yes some guys will mix low ash 2-cycle oil with diesel fuel on their diesel engines to help with lubrication.
