What is the best brand and where I can buy 20% to 25% Nitro Fuel?

The best brand is Byron gen2 or powermasters. Buy it at the local hobby store.

Hi Rich,
I've used several fuels, none of which I recommend over the others. I will use Odonells 20% nitro 10-12% lube, as I can source it locally.
Amazon sent me a gallon of Torco 20% nitro 14% lube, but that is about $40 shipped. I don't see that available at the moment.
Other online store sent me Powermaster 20% quart.

Your engine manufacturer should probably give you recommendations for break-in and running fuel.
Generically, from things Ive read and been told:
Use 20% nitro until you can prove you want/need something different
Use 10-14% lube with some castor oil in blend, for break-in and running. Bias high in range for break-in, and lower in for running.

There is a load of info on nitro fuel and lubricants, and expect to become knowledgeable on the subject.
Happy running.
