I have the race program on my tt stage 4 but the best uk fuel around is like your 93 octane but i can purchase some 104 (USA) octane from www.aaoil.co.uk then click on products,racing fuel then Sunoco GT Plus technical specs.
It contains ethanol as the oxygen carrier! Would this be ok to use.
Would it cause any damage?
Cheers.

 

Absolutely safe. GT plus is excellent unleaded fuel.

 

Thanks,
It wants to be good... its costing around $300 per tank full.
Distributer claims it will clean the engine too, so no more carbon.

 

GT 100 is the best I have around here. I'd run GT 104 in a second if it was nearby.

$300.00 per tank? Wow...you must really want that extra 30 awhp.

 

I've been using Sunoco GT104 exclusively for 5 months now without a hitch . . . it works great!!!

Just ordered 100 ltrs. Dont think i can afford to run it on it constantly though.......way too expensive over here.
Appreciate your replies.
So will it be safe to run the car flat out in 6th on this fuel?

 

Yes. That fuel will provide more protection than any you've used so far.
