Re: Best Gas
All gas is the same, the difference being additives. I shop by price and have for 45 years. I have never experienced a bad tank, but I do try and avoid E10 (10% ethanol) in my Audi A6 as it has a bad habit of throwing catalytic converter CELs in hot weather when I use it. If you have any worries, stick with the larger companies: Shell, Mobil, BP rather than mom/pop convenience stores. You'll want to fill up before heading back to the great white north as gas is still cheaper here.
