*EDITED* AGAIN

AFter all this.. I go to my LHS only to find that THEY DONT FRIGGIN CARRY Airplane fuel! GRRR..

Where do you guys get your fuel? I dont feel like paying $15 per gallong and a damn $20 HAZMAT fee on top of that. Thats insane!

And if your wondering why this post ist back up here.. Ask tom.. he made me to it lol (j/k..I just wanted to make you go "HOLY SHEET NOT THIS AGAIN!! LOL)

Previously this post was about a coupla questions which were answered by dbow and others

Now the question remains in my head..WHY?

Because the supplier of the fuel says so?

If airplane fuel actually has MORE oil, especially castor.. which helps engines with heat, whats the problem?

The only thing I see is.. The nitro % in airplane fuel tends to be less than cars in general.. any way to fix that?
Can I just buy a can of nitro and mix it in? (I'm serious!)

Thanks

Sorry Ram....I just thought I would add a little humor to start things off.


OK....I'm gone!

Well this is one pony that just wont die!
IT has a stone skin spell on it! lol
But this is it.. I'm determined to get the truth out..
I wanna know why/why not..
People may be tired but we keep beeching at other people and were not making logical conclusions

I'm not totally convinced one way or another. I will reply with one question; why do the vast majority of car engine manufacturers recommend NOT using airplane fuel in their engines? Nobody so far has been able to answer this question.

BUGGIES_R_US

From what I know.. Airplane engines DO have lower oil% as well as low Niutro %.. This will lead to engine overheating AND underperformance..

In my opinion.. thats why they tell us to stay away.. they want to preotect their business!

One reason that engine importers (seldom the manufacturer) recommend car fuel (that costs more) is that they also distribute the fuel they recommend. When paris racing was importing picco engines, they recommended using only blue thunder racing fuel (they were the exclusive distributer of blue thunder at the time). Traxxas recommends traxxas fuel (go figure), trinity imported engines recommend trinity monster power fuels, etc.

Its up to us to figure out what is true and what is not.
Its easy to get cought up in myth and assume that its fact!

When compared head to head.. other than the obvious nitro and oil % difference in a lot of cases I dont think there is any difference..

I looked at the hobby shop the other day and found airplane fuel with 15% nitro and 18% oil which is pretty much the same as what I am running in my car. It had blended castor and synthetic oil. I am curious as to why I am not supposed to use this in my car. Even the guys at the shop said I shouldn't, but I don't know if they have a reason. In my manual it didn't specifically say to use r/c car fuel and not plane fuel. It just specified oil and nitro percents recommended.

Hey Ram.....What's the scoop on the "BUY IT NOW SAVAGE DEAL" from the "new guys"?

Did you swallow the bait?


Ohhhhh...and to keep in harmony with this thread about glow fuel....Be sure to always add some to your tank just before you try and start it so your engine will run!


Just my 2 cents

BUGGIES_R_US

xxxNT..
Yeah I would go ahead and get the airplane fuel..BUT

remember that 15% nitro will be a little less.
20% is normal for .12-15 sized engines
and 20-25% for .21
and even 30% for the ones that really wanna kick it

Cary:

Well it actually looks good.. BUT the price is around 365.. not a bad deal!
Like I said if he puts it on ebay.. we have no problem!!
Well I'm not buying one so I dont really care.. I Was just checkin it out. But looks ok!

So why all of the secrecy with us needing to send our email? Can you offer more details about the "process" that they are offering?

BUGGIES_R_US

Well he mentioned something about comission for selling
guess they wanted to get their comission or something..
you know one of those pyramid sales things or soemthing

Oh well screw it.. I'd rather pay 400 than risk 365 eh?

less oil in airplane fuel? the 9 dollar sig that i use has 20% oil.

My Feedback: (1)

I have been involved with model aiplanes for almost a year now, from what I have learned so far Airplane fuel usually has more oil than the common car fuel brands.

The difference in the fuels from what I have seen is the amount of synthetic and castor in the mix.
If a particular oil states that it has 18% oil then part of that is synthetic and part of that is castor.
Synthetic burns off at a lower temperature than castor and thus does not provide as much protection for those lean runs and so forth.
The basics of it is that airplane engines tend to run cooler and the car engines much hotter. Especially if you over power your planes a little, you dont need to run much higher than 1/2 throttle to get good power. This is also one reaosn plane engines last 10 X longer than car engines.

In my opinion castor is of more service for the cars because they run hotter, so with that said I like to see more castor in the blend for the car fuels. I run Wildat Eliminator in my cars which is 18% oil, Wildcat does not label whats whithin that 18% on the bottle.
They do however list it on the Extra premium 15% airplane fuel. Its 80% synthetic and 20% castor. So what you actually see is about 12% synthetic and 6% castor in that particular ariplane fuel.

Thats about all I can offer the group. If you really want to get deep into the fuel then the best thing to do is read up on the fuel forum. There is a tremendous amount of information there and you will learn more than you want reading in there.

NOT AGAIN!!!!!!!!!!!!!!!!!!! EDITED

BUGGIES_R_US

OOPS!

I got that backwards!
Ma bad.. I got my info backwards.. I wanted to say airplane has more sorry!

Ok well heres my final statement..
I have the wildcat eleminator fuel as well.. its great but after this I'm switching to airplane fuel!
Thats that.. unless someone can run a damn experiement and prove otherwise!

Ram,

Stick with the eliminator or do a test.

The Aiplane fuel Wildcat Extra premium 15% actually runs my car engine hotter than the 20% Eliminator fuel.

My best guess is that the Eliminator has more castor, I also got more smoke out the pipe with the Eliminator.
It is a lot more pricey but I dont run my cars that much anymore.
I do plane to be running my RC10GT fairly often in the summer but still plane to run the Eliminator.

In general I have been running Wildcat fuel for quite a few years now, I have tried just about everything and always come back to the Wildcat.
Its just my personal choice and I like the way it smells.

HAHA damn man that thing burns my nose!!

But heck dude I bought a Rossi black magic
MY mugen 4XR works is under way!
Some people were saying that they always run that particular engine at 300-325 degrees!!
Any thoughts on that?
Only difference is that this motor has a ceramic piston head
You say I should stick to car fuel eh? its 24 bucks a gallon
I'll go check prices some but allright I'll stick to it

Dont be slamming on grampi, grampi is somewhat new to the Nitro cars but is not new to the R/C community.

If I remember correctly he has over 20 Years with model airplanes, I imagine he could teach us quite a bit in that realm.
Or is it crash that has all the model plane experience?
Either way no need to bash for asking a general question.


I might go ahead and add that Morgan airplane fuel is 17% oil as per the website. Cool power and Omega both contain 17% oil.
The Morgan sidewinder car fuel is 10% and 12% oil.

Yes ram thats my suggestion for the general .12 size engines and so forth.
BUT I suggest you do some testing with the different fuels and stick with what you like the best.

Thats what I did and ended up with the Wildcat, its by no means the best, just what I like.
And yes the elimnator is expensive.
I get my plane fuel at Funtime Hobbies for $11.99 a gallon which is a great price. Roger the owner of this shop is one of the best owners in the business. He really puts forth the effort teaching, training and promoting the hobby.


I cant not comment on the .21 size engines as I have no experience with those engines. I would assume that they would be about the same as far as fuel goes. I do have a good friend that races 1/8th on road with a passion. He runs BK 30% in his cars and races @ the bowl.
You need to do some research before you run that engine.
Sorry I cant offer much help. When you firgure it all out though do update us as to what you find.

Anyhow, let me know when you get that thing going I would like to see it run.

Also Ram, Let me know if you want to try out the model airplanes.
I would have no problem puttin ya on the buddy box and letting ya get some stick time.

I will be starting back flying in a couple of weeks so let me know.

You know every time... *cough*

You know every day.... *cough*

You know ever hour when we have this discussion, \there are one or 2 things I never see discussed...

First, I don't know the differences between fuels... But there needs to be something, I'm sure they are similar, and interchangeable to some effect, but if you look at car vs. airplace applications they do differ...

1. Airplanes during flight get lots of cool, clean, flowing air during flight. With Cars you can't guarentee it.

2. RPM's during an rc race go from 5K - 40K back to 5K in seconds, over and over, and over. Airplanes, engine's are less abused.

3. If you go into the airplane forum, are any of them using car fuel? why / whynot?

Let's see.. I race atleast twice a week... Bought a gallon a month ago... still have 1/4 left... I'll drop the extra 5$, so if my engine croaks on me, when I send it back to HPI, the cool blue coloring on the inside will show that I was following directions...

grampi

I think dbow is on to something here. The difference could very well be in the amount of castor and syn, rather than the total amount of oil. I agree that many airplane fuels have an equal amount, or more total oil content than car fuel. But if they don't have the right amounts of both syn and castor, that may be where the problem lies.

o crap grampi thats too bad the airplane blend i run has half synthetic and half castor not 80% syththetic and 20% castor.
hmmm looks like the fuel i use fits the bill perfectly and wow i dont even have to pay 25 dollars a gallon isnt that something.
