Is it bad to keep nitro fuel in the car?
 

I have a new engine in my nitro Rustler and I put nitro fuel in it, and it been in there for 2 weeks is that bad? What will happen?

Thanks.

Always dump the fuel from the tank after running then put the ignitor on and turn the engine over a few times to make sure there is no fuel in the system (lines, carb, tank). After all the fuel is out put some after run oil in the carb or glow plug hole. Turn the engine over a couple more times and set the piston to the bottom.

The alcohol in the fuel attracts water. Water leads to rust. Proper care and maintenance will make the engine last longer and easier to start.

Yeah always empty it out. It will also gum up and you will have to clean the carb, lines, and tank if you don't

wont that hurt the engine ethough after u empty the tank than running it ,i empty the tank and take the fuel lines off to get the fuel out,i know most fuels now have rust protecters i do put in after run though if i dont run it for a while

No, it won't hurt the engine. I've done well for many years by draining the tank and running the engine completely out of fuel.

Thats the way you suppose to do it...... Correct indeed
