Agreed- (G. Wallace) It would be interesting to see the difference between the two octanes.
Of course there is the debate on which company fuel is better? (chevron, Texaco, 76, Sunoco etc...) I really don't know if there is a non-biased site that has data on better fuels.
Last summer, people (incl friends and relatives) were having fuel pumps going bad on their cars here in the southern Ohio area. It was blamed on bad fuel at the refinnery in Kentucky. The deal was that you pay for the fuel pump to be replaced and the refinnery will send you a check, which they did after about 6 weeks.
Of interesting note was that the blame was not going on the local BP, chevron, marathon gas stations, but on the refinnery itself. The answer to this was that all the gas produced for our cars in this region comes from the same KY refinnery and that there is bascially no difference between fuels. (BTW, we do not have a Suncco station here in this area)
I was a little shocked to hear that there is little difference at all between brands of fuel. I usually get my gas from the same station each week due to its high quality (they change their filters often, of which you can see) and good price. In the past, I've always thought that gas station "X" had better quality gas than gas station "XX".
Anybody want to shed some light on gas quality? Has anyone heard about the same gas used by different gas stations?
