I blend my own fuel. I use
Model Technics ProPower 16 here in the uk and dilute that with methanol at 50/50. This gives me 8% nitro and 9% oil, so far all has been good. The engine remains smooth and the engine is easy to start once there is plenty of fuel primed. I have a Sonic Tronics auto glow system which is absolutely brilliant-worth every penny/cent.
I am also very careful to run the engine absolutely dry after each run and put in
after run, so far so good
