I totally agree with what you said about advertising mythology, Tex. I've heard bad things about Shell and a few other oil companies in the past though with regard to oil quality, and that sportrider test didn't speak too highly of them either.
At this point, I only put BP or Sunoco in my fuel tank due to the stats I've seen showing where/who they buy their oil from. I have no interest in supporting the whole overseas oil BS and make it known at the pump.

Seems Sunoco is clean, as well as Shell. This backs up previous stats I'd seen where Sunoco had 0% for 2004. BP used to have 0%, but they seem to have increased imports from the middle east. I only buy gas anywhere other than Sunoco if I can't find one nearby and am running on E.
