Since we can only get 91 octane at the pumps up here I have been using Chevron or one of the name brands. Still crappy. I tried a tank of Valero and couldn't tell it was any different from the Chevron or Union 76, except it was about 3 cents per gallon cheaper. It is to far to drive to get the 93 unleaded without any Ethanol in it every time I need gas.
Do any of you chemists or gas people have any suggestion about which is the better brand? I won't fill up at the mini marts at all. I am using this in a 1965 Comet with a stock 289 two barrel carburetor.
