Nitro Rc Fuel Question Need Help

Question

I have o-donnel 20% fuel, Is it ok if i switched to traxxas 20% top fuel for my hpi evo? Thanks

Answer 1

Switching fuel especially of the same nitro percentage should be fine.

I have used both fuels and if I remember correctly, the traxxas fuel runs a bit richer then o-donnel.  If you put a gallon or less then switching shouldn't as big a deal as an engine with 3 gallons through it.  I personally am a fan of the o-donnel fuel and have been using it with good results.  Just try a gallon out and see if your engine runs good, just remember to tweak your high speed needle and maybe your low speed.  Shouldn't harm your engine at all.

*If you just have a gallon of traxxas fuel you want to use then go back to the o-donnel then you have nothing to worry about, I have put different fuels in mine when I have run out.
