I was wondering if anybody here uses airplane fuel in their r/c cars, or if anybody mixes their own fuel?

no

I would suggest searching. There were many discussions on fuel and this post will truly explode down to personal preferences.

Again, stronly suggest doing a search on fuels first. I am sure your questions will be answered.

No,I dont use anything but car fuel. I dont mind spending a little more for the fuel blended for my 350$buggy engine. No one I race with or anyone I know use anything but car fuel in there cars. Read the instructions with your engine and use what the manuf. recommends to get the best performance and life from your engine.

It's doubtful anyone would use anything but car fuel in their Nitro car motors.

As for mixing your own, most companies do computer controlled mixing for better accuracy (or so they claim). The fuel isn't THAT expensive to warrant the effort of mixing your own or finding alternatives.

30 dollars a gallon at my lhs is expensive, maybe not to you, but that is a lot of money to spend on a gallon of fuel.

Once and for all: If you don't race and compete, THERE IS NOTHING WRONG WITH USING AIRPLANE FUEL. Its the same stuff just a little more oil. You will NOT lower an engine's life by using more oil, in contrast, you will experience lower engine life by using low oil (as in RC car fuel).

Folks, fuel isn't rocket science. Don't be fooled by slick marketing and higher prices for car fuel. In this case, you are not getting what you paid for. RC people who drive sport and don't compete are getting ripped off by PAYING MORE for less, less oil that is.

Slick labels on the fuel jug and dyed fuel colors is just part of the gimmick to let you think you are getting something special, you aren't.

Yes, for PURE PERFORMANCE, a fuel with less oil will outperform a fuel with more oil when nitro % are equal. However, there is a cost to this: decreased engine life.

I'm probably going to reignite the fuel controvey among car drivers...just doing my part to stamp out ignorance.....

Very well stated homebrewer I agree 100%. see the problem is that alot of newbs go to thier lhs to get thier car and get help tuning it. the lhs will sell them the "car" fuel. And they will buy it eveytime from now on. this is how the money is made. It is without doubt a marketing scheme. nothing is illegal about turning a fuel a different color and selling it for more. Also there is nothing special about the fuel that says "specially blending for car engines". For the record I have ran "airplane" blend fuel in all my engines, and ive had boat,plane, and car and they have always ran very cool and produced plenty of power for my needs. Im going to leave it at that.

i posted on this some where else, not going to type it all otu but basically some people around here use airplane fuel in there RC10GT and otehr vehicles, and get better performance and lower tempartures with airplane fuel.

Gotta agree with you on that one

thanks, jus do your reading before you use airplane fuel, but it'll work just fine

ya I already use airplane blend and it works awsome. To be exact its sig airplane blend, 50/50 mix between syn and castor.

how much does it run? whats the % on it? I don't know much bout airplane fuel, jus whats been said around here.

I fly heli's and so one day I ran out of car fuel and so I put in some 30% heli fuel in my t max. I was shocked how much more power it had and the temp stayed right at 210 full tank and 225 at the end of the tank. I now only run 30% heli fuel in it and the motor has about 3 gal threw it. Try it you will like it!!!
Mike

I run 10% airplane fuel in my buggies.


an ittthhhh ttthhhhuch a pretty pink wwwhhheeeeee!

Okay I have killed two more cats because of this fuel Thread Thing......Any more post on this topic and Garfield gets it!!!!!


Airplane fuel in your car.........Wow master the possabilities!!!!

Tom (fuelguy)

I can get a gallon of 20% with 16-18% oil for 11 bucks. Too me sig is the way to go because they give you half castor and have synthetic. Ive seen some car fuels for 30 bucks a gallon, I could get almost 3 gallons of sig for that much

Not this discussion again.....sloooly I turned...step by step...inch by inch...
I use airplane fuel in all my nitro powered models. Your engine will last much longer than it will ever last on car fuel. I have never NEVER lost an engine due to using airplane fuel in my cars. And BTW, it's about half the cost of car fuel. I though this airplane/car fuel thing was a no-brainer?

I wanted to try 10, 15 or 20 % airplane or heli fuel, but I see there are fuels for 2 & 4 cycle. My question is, do I have to get the 2 cycle one ? And do I have to re-tune my engine once I use this new type of fuel ? I guess I am right....by the way, the airplane fuel are cheaper than car fuels. Before I forget, how about my glow plug, do I have to change it to cold or hot plugs ? I have an HPI .12 SS engine, just for the info.

Any response are most welcome.

yah rc car engines are 2 stroke

Okay I have Killed GARFIELD!!!!!!

Since he is dead, yes get the two stroke fuel....Because well your nitro car is a 2 stroke (no brainer)

Second each time you change nitro content you will have to adjust your needle valve (hi speed only) accordingly about 1/8 of a turn rich or lean depending on your situation. This takes 35.7 seconds and is also a (no Brainer)

tom

So let me get this straight.... Airplane fuel costs about half what car fuel costs, yet your engine will last longer because of the higher oil content?

If it will make my brand new Sirio .18 last a bit longer... I'm in...


Thanks for the info......

The light bulb keeps flickern..............................


Another cat is dead Celly!

For the most part, go with 2 stroke airplane fuel instead of 4 stroke fuel for general sport rc car driving.

Reason: MOST (but not all) 4 stroke fuels contain 100% synthetic oil and a small high revving engine would be better protected by a fuel which contains castor. THERE ARE EXCEPTIONS TO THIS: Some 4 stroke airplane fuel makers use castor/syn blend and are 16% oil content by volume, some 4 stroke fuel makers are 20% syn oil, some are 18% oil.

Your best bet is to be an educated consumer and know what you are buying.

Any RC airplane fuel that is between 16-18% oil content (syn/castor blend) will run fine on 15% nitro. If you use a 20% OIL BASES fuel, I'd use a higher nitro 20% or higher to ensure decent idle and transition and top end.

I'm glad to see that the people out there are starting to realize that they don't have to spend 30 bucks a gallon for fuel.

yep thats correct just make sure you buy fuel with a good mix between castor and synthetic like sigs champion
