Stay away from octane boosters, they may have worked at the time of carburettors, but I would never put that stuff into my M6!

Yes, performance cars or high performance cars are running with 98octane. Shell sells racing fuel 100 and ARAL sells 102 the same as the
DTM are using. And yes you feel a difference. The knocking is much less. Ok additional I have a tune so 98 is the lowest octane I can use.

I don't know where you live, but Sunoco sells 100 octane at select stations (under lock and key). When you get there, just make sure you pull your pants down, and grab your ankles...
IMO, high octane on a stock street driven M6 is overkill. And I can ensure you will not feel the difference. Open your wallet (expect $150 for a full tank) and see for yourself. |
I disagree, as mentioned above you feel a difference. Not gaining HP but the engine runs smoother and maybe the throttle response is little better. And yes you pay for it. ~140$
