Amazing! Engine knocking fixed.

[Rocket 99GT]

All I did was changed the octane from 93 to 94 (I found 94 at a sunoco station).
The first thing I noticed is that the "bucking" was not there anymore (was cause by seting my time adjuster to the maximun which is 14).
The test was this morning, there was ice in the winshield, when I started the beast it kind of knock for few seconds then the noice whent away.
I wish I could find even higer octane but on the other hand I paid 1.57c while regular is 1.34c, oh well if we are driving V8 is because we have the money to pay for the expensive gas.
