I think what you are seeing is from a fuel additive. Are you adding any octane boosters to your fuel? If not try a few tanks of some other brand of fuel and check them again. Different companies add different additive packages.

Nope, no additives. I did switch to Shell gas, though. Maybe their "super high quality" gas is the cause? I was just curious. Luckily it's not bad. :D

It's butter, man, you know, from the corn!

Nah, its just the combustion reaction residue to one of the additives Shell uses.

That's gotta be it! I took off the air filter cuz it was so dirty, and I swear I got 10 more horsepower so I just left it off!! :D :rolleyes:
