Re: The Truth About Gasoline
Quote:
Detonation is not determined by the flame front except if the flame front is slow. Detonation is the spontaneous combustion of the end gas volume prior to the arrival of the flame front. The very sudden combustion sends a high velocity shock wave across the cylinder which is measured in kilohertz. The pressure waves remove the protective boundary layer from the piston and head allowing metal to be eroded by the heat and pressure. Detonation always occurs after top dead center but very close to TDC. |

Re: The Truth About Gasoline
I agree with most! Octane is a money making tool! Since the advent of computer control systems on vehicles in the mid 80's, there is no need for high octane fuel!!!! Only if you are HIGH PERFORMANCE IE: compression, cams, gearing and so on! But even when I was tooling around in my 56 chevy 301 small block in 1969; I just put a couple of mothballs in my 14 gallon tank!!! You can still buy them anywhere! AH! Ketones and Acetones!! Burn the house down!!!!

Re: The Truth About Gasoline
When I was 16 filled up my 1991 Geo Metro with 93 and put in 4 bottles of Turbo 108. The car had a hard time starting with that tank of gas.
