Nitrotane?
 

I have a dynamite .28 in my savage x. I went to the closest hobby shop and the best fuel he said he had was nitrotane.. ive broken the engine in on this fuel and saw somewhere on the web it has crazy low oil percentage. what would be a cheaper fuel and safer for the enginne without sacrificing to much engine performance?? I was told before that airplane fuels cant be used with cars because they arent designed to be run at such high rpm's. thanks for your replies

RE: Nitrotane?
 

Car fuels do not have enough oil to be used in airplane engines

A car engine will not run as fast on airplane fuel because the oil slows it down

I don't use car fuel

Nitrotane is a Losi product

You can use airplane fuel, but you will have lower power and you will have to tune it more acurately due to the extra oil. You are not supposed to use car fuel in an airplane model engine, the loser oil content may harm them.

You need to use fuel with 17 to 20% lubircation in it. It takes that much to make sure the connecting rod ends get proper amounts of lubrication. Yes, it will run faster on the low oil content, but you asking for an inflight failure of the connecting rod. It is perferable, IMHO to have some Castor oil in the mix - say 2 to 4 ounces per gallon. That will help in case of a lean run.

Buy some airplane fuel. It will properly lube your engine and make it last a long time.

Not if you're using a good quality oil.

I run just 12% oil (good quality) and with over 200 hours running on such a brew, my oldest engine shows *no* sign of big-end wear or other damage.

Not all oils are created equal.

Yes, my 12% fuel brew consists of 10% hi-quality synth and 2% castor.

No, most of these buggy engines are designed to run on low-oil fuels. Some times they just don't run as well on hi-oil brews.
