So last week I went to Sunoco to put some racing fuel in the beast 70% 260 GT and 30% regular 93. The M5 performs amazing with racing fuel.:biggrinbounce: Touch the gas and hold on. So after a week of cruising on $7.43 a gallon for the special OPEC juice I went and put 93 in from Shell.
What the heck did I do that for. The car felt like it had allergies. Sluggish and the tach bouncing all over the place.:M5rev: It must have taken a good 1/4 tank before the car settled down. I see that on the board alot of people say they use Shell because of course its TOPTIER but I have had to many misfires and unstable idling when I put it in. I think i I am going to stick to Chevron which is also TOPTIER . Not trusting what coming out of these Shell gas stations lately. My opinon and thoughts.
Here are the specs on the racing fuels available out there: Racing Fuels
