" but in my small area I am lucky to find a Shell station and Chevron is out of the question"
Me too, we only have a Chevron, but it is a small, old facility with low volume. We do have a new Sheetz which I am thinking of switching to. They are supposed to have high-quality fuel storage and delivery systems, but I am not sure about their fuel, as they are not listed as toptier. Anyone have experience with their fuel?
