I have a 2001 TJ, and with mileage around 22,000. Every time I purchased gas from Mobil, and Exxon, the "malfunction indicator light" was always on, however, after I pumped gas from other gas companies and drove for a quarter of the tank, the light went off.
Since my car is in pretty good condition, and this only happened when I bought gas from Mobil and Exxon, I think it's okay, however, I still get a little worried, and sometime I don't have other choices to pump gas ...
I wonder anyone here has same or similar experience? or I do have to perform an engine check.
Thanks.
