Are you superstitious about where you buy your gas?
Had a problem with my car, transmission was jumping, only 56000 km on it. Usual place for gas was Esso, far as I know they have a good rep for clean gas. Filled up a few weeks ago at Petro Canada and the problem disappeared. Not only am I trying to always go to the same Petro Can near my home but also the same pump #8.
