Okay, car is running a little rough, and the fuel gauge is off (only a little) I was told that the gauge issue is probably the senor in the tank-tends to be an issue, I guess).
I was told by the dealership NOT to use anything higher than 89 octane (was going to fill the Cobalt with a tank of 93), and to do a fuel system cleaner only.
So....I've heard great things about the Chevron w/techron, but I also know seafoam does a great job too. A few questions though:
Would seafoam be too strong for a car like the Cobalt? I was told that these cars don't handle high octane fuel changes well. (which could explain the issue at hand that came up after I used 89 in the tank.
I figure it needs a good cleaning, just not sure on which way I should go...
