Well its been two days since ive seen a cel (o2, ive changed both sensors and checked the wiring), and i couldnt figure it out until tonight. Since day one, i've came to belive that sunoco 94 ultra is the ****, that it was by far better gas than any other. Ive also heard mobil is shitty and not to use it but its ok compared to getty. I had to buy some moble and bamb no cel, and i have gotten them at least twice a day, i romped on the car really hard and it wouldnt kick a CEL. Damb i think my problem is solved, and i guess moble is better gas?

What do u guys think?

 

I've never seen either brand; I only use Chevron Supreme and Supreme Plus (92 and 94 octane with Techron additive). That's what I've heard is the shiznit
