Default Switching fuels

I went to go get some fuel last night from my LHS and he asked me what fuel I was running. I asked why and he said that whatever fuel I use to break in the motor with, that I should never switch to a different fuel for the life of the motor. Is this true?

So far I have ran 1 quart through the thing, overall I have really enjoyed it. Other than a few small issues I have been really happy. The only real issue that I haven't been able to fix is this electrical issue. At least I think it is some kinda electrical issue.
Possible electrical issue

Brand of fuel ??
That is for the most part is a personal preference. The oil is what varies. And different brands will take a different tune

Nitro content will/may affect motor life

People have been arguing which fuel is better for years.

I say find whats available, affordable, and you can get a good tune on, and stay with it. But changing fuels in a pinch will dont affect much

Don't change to a different fuel for the life of the motor?!?! Sounds like the LHS is getting a kickback from the fuel distributor...

I had this same question not too long ago. Going to a different brand of fuel will not cause any detriment to your engine. Keep in mind though, that if you change nitro content, say going from 20% to 30% or vice versa, you will likely have to change the number of shims under the head.

I've got a Traxxas 2.5R in a T-Maxx that I've been messing around with. I broke in the motor on O'Donnells, and ran a gallon through it. Now I'm about 80% of the way through a gallon of Byrons, and I just picked up some Torco. I'm trying a different gallon each time to figure out which fuel I like the most.

Find a brand you like, and stick with it, but don't be afraid to try something new from time to time. You never know, you might find that you like that one more.

I switched form Bryon's 20% to ColdFusion 30% and never had a Problem My motor ran even better with ColdFusion 30% so that is the Fuel for me. But as the guys said it is not a bad thing to try other fuels it wont hurt your motor at all and you might find a better fuel for you motor and you driving style.

How do you "flush" the motor?
If I was going to switch from say 30% O'Donnell's to another manufacturers 30% fuel what would be the process?

The RTR buggy had o'Donnell's 30% shipped with it. I went ahead and got another gallon of the O'Donnell's from my local hobby shop as I wasn't really sure. I'm not trying to be "cheap" but it does seem that the price of the O'Donnell's fuel is 50% more than everything else.

Where do you recommend buying fuel?

Switching fuels isn't a problem as long as it's a good fuel.

I do like to break the motor in with the same fuel I plan to race with. I don't buy the whole "special break-in fuel" deal, though adding a little extra oil for break-in isn't a bad idea. Once it's been broke in and run a while, run whatever good fuel you can get.

ColdFusion sales a Brake in Oil you add to your fuel to brake in a motor i have used it on 2 motors and it worked GREAT made the motor brake much better and a lot EZer on the Rod and Pinch of the sleeve and the Brake in Oil will Last for ever you just add it to the fuel you are using and when the motor is broke in save the rest for other new motors.

Hobbytown is the only hobby shop I know of near me. I was out of fuel and needed some to keep playing with it this weekend so I went ahead and got some anyways.

Where did you find that fuel for 80 dollars a case?
