Is there anything problem wise that could be caused by putting either one of these octanes in my T/A? Or at least half tank mixing w/ 93 octane? I have a cam so was just getting some opinions out here... Theres a place out by me selling 110 for 4.69/gal. Might as well since its not too much more than premium.

 

as long as its unleaded......leaded will **** with your O2's and Cats.

 

huge waste of money and may hurt performance in a stock compression ls1.

 

really? i picked up 2 MPH and 2 tenths running unleded 110 (i think that was the octane rating) in my car. i made back to back runs. 3 on 93 and 3 on race gas. all 6 were good runs.

 

Then the car must have been detonating before adding the high octane fuel. That is the only way it will increase power, the ability to run more timing without detonating.

 

it was like 95 degrees and track temp was 135, im sure the comp pulled timing anyways. there is nothing wrong with running race gas in an LS1.

 

Theres a place close that has 100, so I'm going to use that, see how it runs!

 

make sure its unleded. if its not, the nozzle wont fit in your fuel hole.
