So then this is something I don’t have to worry about? Atleast until a few thousand miles or should I do as said above every 5k miles or oil change
I don't believe so. In my previous truck I used Kroger gas exclusively due to the fuel points discount. One day one the way home, I looked at the gas guage and it was at a 1/4 tank, 1 mile later the truck was out of gas and I coasted into a tom thumb gas station with the gauge still read 1/4 tank. I put in 1 bottle of Chevron Techron for the next three fillips then switched to Quick Trip and in a 6 week period, the gauge started reading accurately again. The truck never drove erratically or acted like it had an injector issue at all, dead smooth 175K mile 2003 HEMI truck.
From that point on, I've only used Top Tier gas in my cars and never had that happen again.
I have a Z06 also and they've had the same issue from time to time with non top tier gas, I never experienced it but have heard of many others having the same issue in their corvette as I did in my truck so I'll never use anything not top tier again. I put an additional 100K miles on that truck and never had that problem again using TT fuel
