NO its 25% nitro racing fuel from australia ,,im talking about oil content change from 15% to 10 % ,,,guy in hobby shop says there is not that much difference and as long as i can see smoke on full throttle ,but sometimes with 10 cars raceing you may not see smoke from your own car and how good do you have to be with tune obviosly 15% is more foregiving

Why not make your own fuel. I do and it save money here in Australia as well.

I also run 15% oil content fuel (10% Cool Power synthetic and 5% BP Castor Oil). The rest is 25% Nitro and 60% Methanol. This suite my plane (2 and 4 cycle glow engines) and buggy engines equally.

I don't have any issue worrying about a lean situation as the slightly higher oil content gives me an error margin. I'll admit there is a slight performance loss with the buggy engines but it is marginal.

I say try making your own fuel if you're not happy with the local hobby shop supplied fuel. Alternatively look up Ozzie Traders, they make some very good fuel that can be couriered to you door. Here's a link - www.ozzietraders.com

Hope this helps.
