I did run Alcohol on my 572 and I changed my oil after 2 or 3 races and I run it for about 15 years on my bird and I loved it but I went NO2 with new motor on a fogger but I run some nitrous on my 572 with a plate with c16 for nitrous and motor on Alcohol and I may go back the same way spray with gas and run motor on Alcohol it`s hard to beat Alcohol but I run Rupperts carb and belt pump
