When we do an autocross with the 2.0l 914 or the 1987 Turbo I add 1/2 tank of Trick 101 octane gas to prevent any chance of detonation. Both engines have been modified and this is important in southern CA in the summer as temps can get over 100 degrees. The Trick gas has additives that clean the system really well and the inside of the tail pipe will be real clean after a day of full throttle use.
