oh man.. i need to dig up that article where some dude did random testing of pump gas at different stations to test the octane ratings and level or particulates in the fuel EDIT: and found shell as was more likely to have more octane than advertised and had less gunk in the fuel

and another article when someone took a bone stock evo and switched from gas from chevron to shell and made like 10whp just because his car deto'ed less so the ECU advanced the timing

just like oil and filters everyone has their own opinion... personally i purchase fuel from shell (unless its 100, in which case i am forced go to 76)
