LS with a CIA and headers pretty stock on the engine lol but what i meant of gas was like where do you go to fill up because ive noticed that my tank gets fuller with chevron than any othersDo you have an LS or GS-R?
If you have a GS-R, you need to be using premium, which is the highest octane available at the pump.
I use premium in my LS because I bumped up my compression ratio with some ITR pistons, otherwise I would be using the low octane fuel.
I don't see how that works out. The tank capacity is the same regardless of where you fill up.LS with a CIA and headers pretty stock on the engine lol but what i meant of gas was like where do you go to fill up because ive noticed that my tank gets fuller with chevron than any others
