So whats the deal on then and whats the best for the money?

Was looking on www.aaoil.co.uk - they have a turbo specific fuel at minimum order 470 quid for 11 gallons!!!!!!!!!!!!!!!! WTF!!!!!

Also are people running straight race fuel or blends for safety. Interested as I would like to map my car for both optimax and then race fuel later

Looking for a slightly cheaper alternative that will see maximun performance and maximum safety and can get delivered up to scotland.

Cheers for any help
