Just make sure you don't smoke after spitting it outpace said:I agree. It sounds as though your car is doing fine, but I don't know how heavily/lightly modified it is..? If this happened to me, I'd baby the car down to 3/4 tank and then get some 100 octane race gas in there.
Alternatively, syphon that cr*p outta there. A mouthful of gasoline is an experience you will never forget, and is better than the most potent mouthwash that your dentist will ever recommend.
