Switching between fuels

[Vincemaxx119]

Is it really not good to switch fuels on your rc? Traxxas states the fuel you break it in on should be the fuel you use to run all the time. I mean, if you switch to other fuels, will it cause harm to the engine? Just wondering. Thanks.

No - it wont harm anything.

You more than likely will have to re-tune a little, but thats it.

I wouldnt suggest running over 20% nitro in the stock mill. Then again, I run 20 in ALL of my mills with great success. Odonnle fuel at that.

I may not cause damage but its not good. I would change the piston and sleeve before switching to a new fuel. If you want to switch to anything the best fuel is blue thunder.

Change the piston and sleeve if you change the fuel?!?!?!

What on earth would make you say that???

if you go with the same nitro % it will not harm it now if you go for 30 to 20 % it may harm it

Where are you getting your information?

Changing fuel percentages is not an issue as long as you tune properly and let the engine "get used to it".

There is no need to change the internals unless they are already damaged.

ok ok. Lets not get rough here. lol. Thanks for the replies.

lol - you dont have to change your piston and sleeve if you change fuels or percentages of nitro content.

It is suggested that you maintain the fuel you break you engine in with for the duration of the engine. That is purely because your engine is 'used to' it and you have properly tuned for it.

Switching fuels may bring cause to adjust your needle settings.

Switching nitro content can do the same.

Keep in mind, running 10%, 20% and 30 can all have varrying effects on temperature conditions. If you do not pay mind to that impact, it COULD have adverse results. But the same can be said if you dont pay attention even with what you are running now.

Changing the piston and sleeve because you change percentage of nitro is not reality.

The ONLY time I suggest changing ANYTHING internally, are the shims, and that is only if you go from 10% to 30% and cold plugs to hot. You are in fact chaing the timing by changing the plugs, and therefore, may have to increase the amount of head shims you use to allow for more fuel to build up before firing.

But that is a WHOLE DIFFERENT SUBJECT!

Good luck man....

Go Odonnle :thumbup:

Where are you getting this info? Blue thunder is not the "best" fuel....define your terms for what it means to be the best fuel before you mak such a claim.

In my garage I have: 2 gallons of Odonnel 20%, 1 gal. 30% Odonnell, 1 gallon Monster 20%, 1 gal. Trinity Plat. 20%, 1 gal. Trin. Plat. 30%, and other assorted quart bottles. I find that certain engines prefer a certain type of fuel. In O.S. mills Odonnel 20% tends to run cooler than Trin. at a given setting. In Sirio mills they prefer Trin. 20%. I would never say one fuel is the best hands down. I think the most versatile fuel is Odonnell but again it all depends on your application (i.e. you can get more power with 30% but the mill will not last as long if you hold everything else equal)
