Does everyone else's Camaro
absolutely hate the winter blended or oxygenated fuel that is used from Nov to Feb every year?
I have a '11 2SS L99 and I noticed the difference right away in terms of mileage (loss of 3-4mpg). Almost thought I had a leak somewhere. Took me a day or 2 to remember that the stations have to switch to winter blend at the end of Oct. My car also starts and seems to run a little bit rougher on this blend as well. I have fueled up again since then and the station I used for the first tank is a normal station for me to fill up on so I don't think it was bad fuel. Anyone think doing a fuse pull may help?
