yes, i highly advise against using top fuel, way to much oil, making the engine run hotter as less actual fuel for cooling, and oil burns hotter than methanol and nitromethane making the tune window smaller, and it does not have a very good oil package.
if possible try to keep under 14% oil, and 20-30% nitro. for ease of tuning and performance. many run 30% in the 3.3 and have good luck with it.
