[QUOTE="Dreams2Reality, post: 15599431, member: 156690"] Regarding your use of Sunoco, when I first got my car I used nothing but Sunoco 93 and continued to do so after I installed my long tube headers which, after ~50 miles or so, caused the car to start throwing front O2 sensor codes. The "tune" on the car was a Bama - 93 octane tune and for about a year or so, I replaced the O2 sensors, twice, and kept getting the codes (all while still using Sunoco 93). I was aware that Sunoco was not listed as a Top Tier licensed brand but I ignored it ([URL]http://www.toptiergas.com/licensedbrands/[/URL]). One day, I was running on fumes and unable to make it to Sunoco, I got Exxon 93. The check engine light was on for a front O2 sensor code and after 5-10 miles the check engine went off...code gone. Going on close to two years now and the only time the code came back was when I filled up with Sunoco (I had to test it!). I'm not saying Sunoco is causing your issue (or your perceived issue ;)) but I wanted to share my experience with Sunoco. My experience could be completely random and I'm sure there are people that love Sunoco but I'm sticking with Exxon. FYI, Sunoco is now releasing a Top Tier approved gas (Ultratech [URL]https://www.sunoco.com/quality-fuels/ultratech/[/URL]) [/QUOTE]
