I use one bottle of name brand ''complete fuel system treatment'' once a year with full tank of gas. I did that this year on my last tank, I got it at NAPA for about $7. Who knows if it helps, it's possible it does, and I thought I remembered seeing something about that in owners manual.
I run 87 octane 99% of the time. I see slight mileage increase with 89, but not much. Car runs absolutely perfect always.
We have no carburetor.. if that's what you meant by ''carb''.
