Fuel question

[RCNewBe]

I have a T Maxx and I recently bought another one from a co-worker mostly for the parts on it. He gave me everything he had that went with the truck, which included a gallon of fuel. The fuel is 5% though which seems weird. I've always ran 20% in my truck. What would you run 5% for? Should I toss this fuel and get 20%?

Yup, toss it and go with 20.

yea i dunno what 5 % would be good for! Is that the fuel that was previously run in said engine? if so expect the tune to be WAAAAAYYY off. start over at factory settings.

I wouldn't run anything less than 20% fuel.

Fuel is expensive,I'd run it. Might be a little lower on power but I could have enough fun to burn it up.
