increasing compression, running on regular gas?
I plan to increase engine compression through the use of a thinner head gasket... I've already done the math and know exactly what thickness gasket will yield what compression...
what I don't know, what is the threshold where I will need to start using Mid-Grade gasoline? I know every engine is different and trial & error may be the only way to know for sure... I'm expecting somewhere at or above 9:1 compression for mid, and 10:1 for premium
