Default What fuel to use in MR12

What percentage of fuel do most people run on this engine? Does it depend on size of track (I run it on a small and tight track). Also what brand of fuel do people use?

Thanks

Sami

Hi Sami,

Any fuel brand will do for that motor but I personally
use Blue Thunder 30% for the .12s, whether on a small
or large track..

No it wont hurt... The lower the nitro content actually means
more lubrication which is good. This is likewise the some reason
why some guys use a lower nitro content when breaking in a
new motor.

C'mon guys, recommending Blue Thunder and or 15% noname fuel? We've stooped to a new low

From my experience, I'd recommend either O'Donnel or Trinity Platinum, 30% is best for going fast. (Run a cold plug such as an OS R5)

Default O'Donnell

I wouldn't use the trinity platinum 30%. I went through 3 gallons of that stuff with horrible results. Car kept boggin couldn't get it running consistently.

Blue Thunder ain't bad either.

I'd say go for the O'Donnell 20%, 30% if you really want. O'Donnell fuel worked real good for me. Once I switched my cars stopped boggin on me!

I've run Trinity 20% in my .12s for a while now and never had a problem. Just switched to Mugen 20% and like that as well.

I use odonnel and it works great. Mugen (byrons) works well too.

Any name brand fuel should work well enough, except I don't like PowerMaster (among others but I don't want this to be a bash thread). PowerMaster has plainly too much oil of a strange kind, that seems to want to come out of the engine as fast as possible and then stay on everything else.

I don't want to turn this into a bash thread either, but I'd have to say Blue Thunder (at least the "standard", not Race Formula) is pretty bad. I heard an old story on the HPI Forum about a guy who sent some BT to his friend who was a chemist, he broke it down and found less than 8% oil, don't know if it was an unlucky fluke, but I've never used BT again. Stick with O'Donnel (my current fuel), Mugen/Byron, Trinity, or something else name brand.

P.S. Isn't Trinity MHP and HPI fuel the same thing?(Both are made by Wildcat)

HPI and Trinity are both mixed by Wildcat but HPI has more oil...I believe. I've tried HPI and Trinity seemed to burn cleaner

So far I've tried Hpi 20 and 30%, Sidewinder 30%, and Bluethunder race formula. I liek the Hpi because it seems to be a bit more forgiving on tuning, and dosen't make you car smell funny or turn you rengine insides all blue or red. YUCK!

Are you saying Blue Thunder Fuel is bad because you heard
an old story or what?

No, notice that I also said that I stopped using it. So that would mean I have tried it. I wasn't impressed with the way it ran, there are much better fuels.

Hhmm.. That's too bad

I have used and still am using Blue Thunder Race Formula and have once used the Standard Blue Thunder when I first went back to RC and never had any problems. I use Blue Thunder on all my motors. Whether it be a Practice .12 or a Practice .21 or a Race .12 or a Race .21 Motor. From the Common Traditional to the Modified High End ones.

I guess, like you have said, it may have been a Fluke which is too bad and unfortunate for you.

But I am sure that (not all but) a lot of Professional Team Drivers (because I see them use it) and the more Experienced people in Nitro will agree that the Blue Thunder Fuel is not a "bad" brand.

I think that all fuel brands, though I have not used all of them, they are all good and for the most part,
just a matter of preference. I also presently use O' Donnel and Mugen Seiki Fuel and likewise find them to be good.

But still, I disagree when someone says that using the Blue Thunder Fuel is " stooping to a new low".

Plus, when Sami (ttektek) asked about using 15% nitro (since it seem like he didn't want the 1 liter that he has of that fuel to go to waste), I replied that it was okay to use it because the question was "Will it hurt"?
