Yeah Blue Thunder is good. I used to use that but then I had to switch to Top Fuel because the hobby shop that sold blue Thunder closed. And now for the last to years the other lhs stop stocking Top Fuel because it was hard to keep in stock and it was a lot for me ordering it so now after using it up I have to switch to another fuel. I was wondering if Wild Cat eliminator which is what my shop carrys is a good fuel for the Traxxas engine. I use it in my other cars with no problem. I have ran it through my Traxxas pro.15 before but I want to know if its safe to keep using it in that engine. I would love to go back to Blue Thunder but I would have to order that too and its easier to use what the hooby shop stocks. Wild Cat Elimator is 20% nitro and 14% oil content. It has everything blue thunder and top fuel has. Is that ok to use. Does anyone else use wild cat in their traxxas?
