33% nitro

[T-Maxximus559]

Hey I was just wondering if my fuel would still be good it's 33% nitro I baught it last spring and keep it in a cupboard inside so it stays cool(60-70F) and gets no sunlight so I figured it didn't evaporate or w/e. It only has 2 tanks missing out of a gallon so I want to know if its still good. Also I have a 3.3 so I thought 33% sounded good lol, is this too much or is it ok to run 33%? I ran it last summer and it ran good just want to know of its like extremely bad to run this %.

As long as it's been capped it should be as good as new.

Shake well and run it! The fuel will still be good.

Higher nitro can shorten engine life a little,but if you keep it tuned well you won't notice it on most engines. The only issue in your case is the notoriously weak con rod in the 3.3 The extra power from the higher nitro content may accelerate it's demise.

Thanks for responding. I seen Davis diesel rod on eBay awhile ago do you know if there good and should I replace the stock rod while my engine is brand new or should I break it in first with the stock rod? Or should I just break the engine in and run it till the rod snaps then buy new after market rod with piston/sleeve kit or is the engine toast when it snaps?

If you're set on keeping the 3.3,I'd buy and install the DD rod as soon as you can. The engine can usually be rebuilt after a con rod failure,but for the cost it becomes questionable over just replacing with a higher quality engine.

Id run it till it breaks and then pitch it and buy an OS or some other similar engine and put in it. Something aftermarket. That being said alot of people like the TRX3.3 if you feel like you want to keep this engine and rebuilt it after it dies that fine too. If you deffinatly want to keep the engine and you have the money Id buy it and do the upgrade the next time you tear down the engine.

Its really up to you. What are yoru goals and how deep your pockets are. I personally like to try different engines so most of the time if I have one die (or I just dont like the way it preforms right from the get go...Losi Ten-T stock engine comes to mind) I try something else. Unless I know I'm at the penticle of engines for a particular class of model. Like the LRP .28 Spec 3. Once you put one of those in something you'll probably never want to put anything else in it. At least not until they come out with soemthing that spanks it.

However you want to approach it honestly should be fine IMO. figure out what you want in the long run and then take the appropriate course of action from there. Never owned a 3.3 so someone else would have to advise you if its a motor worth keeping or upgrading at some point.

Nitro content has nothing to do with engine life whatsoever, the problem is with tuning. Your tuning has to be good or else you will be shortening the engine's life......same thing goes for the conrod. If your tune is good the conrod will hold just fine, although they are weak. There's two things that will kill a 3.3 conrod....the stress of break-in and lean running/overheating.

33% nitro has a smaller tuning window than fuel with a smaller amount of nitro.
