Blue Thunder Race, Trinity Monster HP, Byron’s, O’Donnell’s, etc all makes suitable fuel. Use fuel with 10-12% oil with part of that being castor and you are set. Do not use fuel labeled “RTR blend” as it has too much oil in it. 12% oil is the max you should use for regular running. 14-15% oil is suitable for breaking in over the first 2-3 quarts..
