Differences in Fuel
 
Just one thing that has been on my mind for awhile, so I decided to see what you guys thought. Have any of you noticed your cars running better on a particular brand of gas, same grade, with just the brand differing? Maybe I'm just imagining it but two of my Camaros just seem to run better, better performance and smoother idle with Chevron gas. One of my other Camaros runs best on Shell. My old Blazer seems to run best on 76. My 2017 Camaro I haven't had long enough yet to try different brands of gas.

My 2013 Z71 Chevy pick up runs good and gets great gas mileage with Valero Gasoline 87 octane.

As for the old cars, Marathon 93 works best...

Lukeoil 93 with some Sunoco 112 mixed in. Easier starting than with just the 93 and better plug and exhaust color.

Unfortunately out here in California 91 octane is the highest grade available directly from a pump at a station, at least where I live.
