Read my plugs, was carbon fouling on 93 pump gas but not on 96 vp?

Sorry but this is just myth. People who really know what they are doing can get tan all the way down the porcelain to the boundary layer.

Not on US pump gas. You do that and it will kill power. Every single time.

Even on race fuel I don’t get color like that, even though you are going to quote Shrinker (out of context) to try and prove your point.

No one I know puts that kind of color on a plug. No one. They must all be idiots.
