hey guys lately ive been getting bad gas and im seeing anywhere from 3 to 10 knock on the rpd ive tried many diffrent gas stations and nothing but 91 since its the highest octane in Newfoundland . what i was wondering is it ok to run a octane booster in my ss/tc ? i did run one bottle and the knock went back down to 0 and stays there.

 

i donno if it would be find in every tank, but just to let u know when my rpd shows knock its really 3 times worse
