Is o'donnel fuel good enough ?

And nitro percentage do you think is pretty safe ?

So far I found that O'Donnell is the best blend on market. I tested different brands and it is clear-O'Donnell make the best lubricants, methanol is very clean (no water was found at all) and nitro is AAA grade. I personaly recomend it.
30% is very safe number.

I've been running O'donnell in all my cars since August. It makes excellent power and the motors tune really easy.

byron's 30% from breakin to the end........ all i run never had a bad batch or a blown motor from fuel....... i also run the team fuel with the 8% oil content at all the big events

Do you want to try JP Racing Fuel? Available around Feb-Mar

Wow !!! I like O'donnell because the color is crystal clear, and the residue is minimal.

DaniZ24, what color is JP fuel ? I suspect the formula is similar as Tornado fuel, little bit yellow..... ouch, no way. How about O'donnell 30%. Will my engine okay ? Some says higher nitro cools the engine and some says it increase the operating temp. Which statement is correct ?

I think more Nitro also comes with less oil, cmiiw. Less oil means less lubrication and generates more heat and of course more engine part's wear.

Some guys have them tested, and the result is 25% is the max nitro you can have here in our part of the world for a .12 engine. My opinion, maybe 20% is the best percentage...

I thought the lubrication packages stay constant within the brand. When you change %nitro then the %methanol changes accordingly. I'm not a fuel manufacturer, but that makes sense to me.

I read about glow fuel article somewhere..... the article mentioned something like this " although % content of lubricants is less, O' Donnel and Byron fuels use special advance formula to keep the engine lubicrated ".

I hope it's true

I use Rocket Science Fuels.

what ingredients? .... don't tell me you mixed it with automatic transmission or mobil 1

Anyone experience the Runner Time or Cosmo RC Fuel?

more nitro does not mean less oil. the rise in operating temperature is not from decrease in oil, it is from the increase in % of nitro.

one bit of warning however is when nitro content exceeds 40-50%. castor oil is actually insoluable in nitromethane. castor oil will separate out of solution (with nitro of 40-50% or higher) unless a co-solvent is added.

In my opinion when you buy a quality motor and it is cleranced properly you don't need all the oil they put in back yard basher fuel...... i run 6% total oil and never have a problem do keep in mind you have to tune your motor for this and for no reason run it lean or it's gone....... i have made my own fuel and now just order byrons pro fuel with the 8% oil..... if performance fuel is what you are in to remember oil don't burn or make power and no two oils are the same in quality or lubracation

I've been involved in RC modeling for my entire life, my Dad flew controlline planes and RC planes when I was just a kid. When Byron's Fuel first came out I was flying 4 stroke airplanes, and they were the first, as I recall that made 4 stroke fuel. For the last 5 or 6 years racing cars, I've used Byron's fuel and never had an engine blow up because of fuel. I've always liked that they use "Klotz" brand racing oil, and find that the engines are very clean inside the combustion areas.

But lately, I've been wondering, if your fuel leaves deposits, aren't they increasing the compression ratio, boosting the performance of the engine?
