is anyone out there using torco race fuel. i used it a long time ago and had problems with plugs fouling out and haveing an orange coating on them for some reason. all the gas stations here in mich used to carry turbo blue gas that we never had problems with. but now i think they are getting the torco gas cheaper so they are all switching over. also i dont want to fry my o2 sencer on my fast system sooner than i need to.
