AJsToyz -> Airplane fuel or Car fuel (3/19/2006 4:37:46 AM)

Ok , seeing that fuel is just a basic blend of oil , alcohol & nitro , whats the difference between car fuel and airplane fuel? I'm looking for a good all around fuel. I don't race or compete. I just want to play in the yard with my car , and go try to land my plane when I have spare time. [sm=biggrin.gif]

There is no difference. The fuel makers make you think there is and charge more for "car" fuel. Mostly just a higher nitro methane content but airplane racing fuel has high nitro and so does boat fuel. Of course you won't find "boat fuel" for sale anywhere. The boat guys know there is no difference. I ran boats for years and I used up to 40% nitro but mostly ordinary 15% airplane fuel. A good all around fuel?? 15% nitro like most guys use. It was the car manufacturers that got that goofy "nitro engine" terminology started. It's a GLOW engine and it runs on glow fuel ignited by a glow plug. Calling a glow engine a nitro engine is like called a gasoline automobile engine a "techroline" engine because the driver uses Chevron gasoline with Techron additive.

car fuel have higher nitro and less oil than aero fuel. car fuel typically is 20-25% nitro 12-14% oil and aerofuel goes from 0-15% nitro and 15-20% oil. Yes I know there are alot of other different blends out there, but this is the most common. I think that if you want one fuel for all purposes a 15% nitro 15% oil fuel will keep you going, although not the most power in the car engine

Thanks !! I thought the cars would have more oil because of the heat factor , but I guess not. Like I said , I'm not racing so a lower nitro count will not hurt my feelings.

12-14% oil?? Using that voids the warranty on most manufacturers engines. OS minumum is 18%. Maybe in Norway your airplane fuel is 0-15% but here it is 10-15% for most sport flying and up to 40% for racing. Even the YS line recommends 20% nitro. No manufacturer recommends less than 16% oil and that is the bare minimum.

For all practical purposes glow fuel is glow fuel and most blends will work in car engines, boat engines and airplane engines. 15% nitro and 20% oil is a good all around fuel.

Cox model AIRPLANE engine fuel comes in two types, Blue can and Red can. one is 25% nitro and the other is 35% nitro. That's more than you 20 25% "car " fuel.



AJsToyz -> RE: Airplane fuel or Car fuel (3/26/2006 9:24:19 PM)

It just seems odd that car fuels call for less oil than airplane fuel, but normally more nitro. Most hobby shops you go into have alot of 15% for airplane and 20 % -30% for cars. I think 1/2A fuel is normally 25% , not sure how much oil though.



loughbd -> RE: Airplane fuel or Car fuel (3/27/2006 1:54:09 AM)

If you want a glow engine to last, use 18 to 20% oil. If you don't care or are all out racing and engine longevity doesn't matter skimp on oil. Guys used to destroy rac car batteries to get the last bit of speed out of them. I worked for a hobby shop and we loved it. Sold loads of expensive batteries.

They sell more engines when you buy low oil fuel.

Hi, I'm new at RC Aviation, will 20% Nitro Car Fuel damage my engine? I just tried starting it today for the first time and it would not start. I tried the following.

-Checked the throttle
-Checked the Glow Plug
-Replaced the Glow Plug Starter battery
-Added full fuel to tank
-Pumped fuel into carb as instructed (at least I think I did)
-Triple checked to make sure I was turning the propeller the right way
-Check for flooding

Anything I missed? Anyone else have a hard time starting their's for the first time? I would greatly appreciate the help!



loughbd -> RE: Airplane fuel or Car fuel (3/27/2006 6:04:33 AM)

Depends on how much oil is in the fuel, most car fuel seems to have a low content. Should have at least 18%. You didn't say what kind of engine it is or how you are trying to start it. If the plug glows bright orange and it has fuel it has to run unless it's physically broken.



AJsToyz -> RE: Airplane fuel or Car fuel (3/27/2006 11:54:45 PM)

If the plugs glowing and the fuel is good , it should start. Did it pop or kick at all ?? Whats the temp like where you are at ??
