do a little research, you will find that most gasoline only comes from a few places. here in UT most of our fuel comes out of southern UT and WY, unless you buy that 7-11 crap,AKA kerosine and ditchwater. try to stay with a reputible manufacturer; mobil, shell, arco, is here to and their fuel is refined locally and its good stuff, try a web seach and check contents. now that I think about it their was a problem about 6-7 years ago when a major fuel distributer accidently mixed diesle and regular, and sent it out. thats how we determined what vehicles were running on it. kerosine smell in the exhaust, killed alot of electric fuel pumps too. My advice find a mobil distributer and stick with it /forums/images/graemlins/thumb.gif /forums/images/graemlins/hack.gif /forums/images/graemlins/weld.gif /forums/images/graemlins/grind.gif
