i have ran both... go with byrons
1) you can see it in the tank when u fill up with the car running
2) i think it produces more smoke
3) byrons does not discolor the pressure line from the exhaust

From what I've heard. Odonnell, Byrons Gen 2, Cold Fusion, Werks, and Torco are all good fuels. Some have coloring agents and some don't. It's an ongoing debate whether or not the color effects performance.
What I've seen. The guys who switch from 30% Odonnell to 30% Byrons Gen 2 (both 9 and 11% oil) lean their cars because Byrons runs cooler.
I got a great deal on a couple gallons of Byrons Gen 2 but have yet to use it. I'm happy with my Odonnells and am going to use the rest of what I have before cracking open the Byrons.

That is the R2R. I have heard sooo many horror stories with O'D R2R running at 325 degrees and still rich bogging. I see in some articles than 20-23% oil is reccomended! Have oils come this far?

more oil mean hotter running engine... doesn't seem like a good thing to have too much oil.

I'm running race 30% OD and borderline race tune, (on rich side) and still get under 250.

which means with bryons I could be runing cooler, but that's isn't necessarily a good thing

Take Traxxas fuel, and all the other RTR fuels out there. They put 15-18% oil in thier fuels, mostly synthetic as it is cheaper, because if a newbie is loooking at fuels they will want the fuel with the most oil as they will assume more oil=better engine protection, exteneded longevity which is false.

I have an RC8T RaceSpec and the manual says for the RTR motor fuel should have 10-20% oil content. I've been running Byrons ProDriver 25% which has 9% oil. Runs awesome, but should i be conserned about the oil content? Why or why not?

this may not matter much as i'll have my Reedy 21 this week, but nontheless i'd like to know the facts about oil content...

if you want to run a fuel with the most National titles run O'donnell if not run the others it's that simple.

That is fine. Byron ProDriver has a 50/50 blend of castor/synthetic oils so it gives great protection along with cool temps and great power. I ran 2 mach 427s on Byron 30% ProDriver for about 2 gallons, and after I added one shim, they ran fine.

Every Hobby shop has to pay the HAZMAT fee, even if i order a case, it still comes cheaper per gallon than what my LHS sell is for.

Sidewinder fuel claims that too. O'Donnell fuel is ok, I will never run it again - I ran nitrotane for a long time and one day Team AE Driver Kody N. gave me a quart of Byrons - I will not switch for a while , I run about 15 degrees cooler - I can see whats in my tank. the inside of the tank and engine is not sticky.


Byrons all the way..............

Everyone has a opinion. Here is my experience.

I've run Odonnell, Sidewinder, Byron, Blue Thunder, Mugen and Trinity fuels. All worked fine. Won with all of them. They all tune different. Never had a issue with engine life with any of them. I've used Odonnell for years now. It's great. I was given a gallon of Sidewinder by a dist. My engine ran awesome with it.

Fumes have never been a issue for me when running a fuel. I've raced indoors at CRCRC a number of times.

Tuning and clean filters are super important.

My first choice would be Odonnell, Byron Gen2 Prodriver or Sidewinder Worlds Blend. All 30%.

A friend runs Odonnell and just runs his engines out of fuel and puts them away for long periods of time. He just told me he took one apart and he was thrilled with what he saw. Oil and no rust after at least sitting in a basement for 5 months. He's runs Odonnell exclusively for 10 years.
