Failed To Break A Myth

[68 Ford Stepside]

I've heard for years that different brands of gas would net you different gas mileage.I bought all of my gas for three weeks from Bp.Three weeks from Shell & three weeks from Valero.BP & Shell gave me consistant 11.2 mpg. Valero gas gave me 9.5 mpg. I drove on the open road at 55-60 mph. 25-35 in town. So the myth stands.Different brands of gas will give you different mpg. By the way,I used the middle grade gas from all three dealers.

That's good information, Wayne! Thanks for the experiment.

in my Mustangs I always got the best MPG with Mobil gas,in my GM vehicles it was Chevron, Shell has never produced that much difference,ARCO about the same as Shell.

ethanol free gas from a local gas station (mom and pop joint) gives me the very best bang for the buck. didn't know that little six in my truck could be so powerful.

I would also recommend staying with Top Tier gas when you can, for the detergent additives they use.

Yikes, that's ugly mileage from a 300!
