The traxxas fuel should be fine. That is what I used in my monsoon until recently because I put a rotostart on it and traxxas fuel has a higher oil content in it and would make my one way bearing slip making hard to start. This will happen to you too even with your pullstart if you keep using that fuel. Nothing wrong with it but it did it to all of my buggies and truggies so I changed and have not had a problem since.
