Gas Brands-Costco Whipple tune
I live in SC where we get 93 Octane fuel. I have always bought my gas from Costco the last few years. My other car is a SHO. I have never had any issues with knock in that car yet Whipple specifically says not to use "costco" fuel. Can someone please help me understand what makes branded fuel better? Costco gas employees claim that chevron makes there detergents for them because there CEO wanted all his employees to have the best fuel and to buy from them. If there is the same amount and type of detergents how can the fuel be different from Chevron? Prices are about 40 cents cheaper so $16 dollars per fill up makes me think!
