Walnut blasted my intake valves

[skipgen]

Thanks. I do not know if the grade of fuel correlates to the amount of carbon build-up, but it helps me compare later on when I inspect my engine. I was going to wait until 100k miles, but I may just clean my valves at about 80k miles when I change my spark plugs since it easier to turn an engine when the plugs are removed.

Thanks JgenG for your time and your answers to my questions! I appreciate it..

No problem

I run Premium in my 5.0 to take advantage of the extra octane & detergents... But on a DI engine it probably doesn't make that much difference for carbon build up since fuel doesn't wash over the intake valves as it does in a port injected engine. Clean oil is more important in this instance.

I agree with you skipgen, and I was also thinking low speed/ city driving would speed up the carbon Deposits? An idling engine does not burn efficiently.

S-o-o-o-o, are you saying that in 1970 when I told my father I was not speeding, I was "blowing the carbon out" that I was actually telling him the truth?

Pretty Much... "Italian Tune Up"!
