You can run 89 octane but the LT4 doesn’t especially like it. I try to use 93 or 92 octane all the time in mine.

Shouldn't have issues with really any major brand 93 gas, Shell and Costco are both top tier.

This is what is making me think I got some low octane fuel in it. I’m going to take it easy with it until I can get some more Costco gas it. Thanks |

I spike mine 10-1 with xylene and it brings the octane to 93. Anything below 92(ish) trips my KS. Check out your KS on a pull or 2. You might have to boost octane above 93 for your area.

Only BP or Costco for me since then, with a bit of Race-Gas occasionally.

The only other thing I could really think of is that I have been pushing the car too frequently in it’s early life and getting enough oil blow by to cause enough oil to get into the cylinders via pcv system. I’m just really guessing with that... think I will check the intake for fun of it. Probably just a bad tank of gas but I will check anyway. Last edited by GrayLT1; 01-17-2021 at 11:54 AM. |

Sounds as if it might have been some bad gas or maybe the wrong gas at the pump. I have found that putting a bottle of STP or Valvoline gas treatment helps some especially in my ZL1. Take it a little easier on the LT1 and you will be rewarded with a better running and performing engine and that’s my opinion only. I have always had better luck over the years with breaking in a new engine easier than balls to the walls driving as they seem to last longer and not have any issues further down the road. Good luck.
