I recently have picked up a couple of gassers. One has been run on regular gasoline and one has been run on campers fuel. What are the major pluses and/or minuses of each? What kind of issues can I expect if I convert either one to the other fuel? Thanks for any comments or suggestions youcan offer for either side.

this is what i have heard so far; regular gas has ethanol which gets the engine gummy and can mess up the carb, it also burns hotter because it has a higher octane rating. Then you get the smell if you accidentally tip it over in your house or your car . I heard that camper fuel makes more torque in the engine, burns extremely clean, no ethanol, forgiving when accidentally poured.

if im not blade bogging youll find me pack puffing

These are some of the things I've also heard. Plus of coarse the cost factor of $8 - $10 dollars vs $2 dollars. I am more interesed or concerned with tunining issues if switch from campers fuel to gasoline or from gas to campers fuel. I'm thinking it's gong to be a simialr thing as when switching from 15% Nitro to 30% when it comes to tuning. The Heli I have that has been run on CF is whistling clean, not that the one run on gas is that dirty.

Switching from one to another is really not going to make a noticeable performance difference in your heli.

Now, you will probably hear all kinds of opinions about how much better one is than the other, but the truth is, there just isn't any hard evidence to support an argument either way. When someone shows me a verifiable test that is repeatable, I'll believe it. BTW, there is absolutely NO proof that camper fuel provides more torque from your engine (sorry kogibankole, it just ain't so).

Tuning is virtually identical between gasoline and camper fuel, and if somebody says it's not, they're doin' something wrong. In addition, it doesn't compare IN ANY WAY to the difference between 15% and 30% nitro. They are totally different beasts.

The real difference simply comes down to the odor (or lack thereof), and cost. True, the camper fuel will keep things a lot cleaner in your engine, but it's also about 4 times the cost of gasoline right now. So, use what works for you based on the known facts, because your engine will run with either one. Besides, it's more about oil mix ratios and tuning then it is about raw fuel selection. Good luck.

I like to know also what kind of mix ratio to use with camper fuel?

There is no difference in mix ratios between gasoline and camp fuel. As stated in the last post, it is more about the mix ratio and tuning, not the difference between gasoline and camp fuel.

Typically, you will find most people run about 40:1 to 50:1 mix ratio with synthetic oil in gas OR camp fuel.

I treat it like my weedwacker. It's a 2 stroke weedwacker. I use the recommended mix that's on the bottle of oil. I think it's 32:1 for regular dino oil. Like the previous post, if you run synthetic you use less oil.

1) Higher octane does NOT burn hotter. It just resists detonation better.

2) If you buy 87 AKI gasoline it is 87, whether or not it contains ethanol.

3) Hanson will not warranty an engine that was run on camper fuel.

FWIW campter fuel is about 55 octane.

I use gasoline with amsoil saber at 60 to 1 all summer and run camper fuel mixed the same for the last few flights before putting them up for the winter. I have heard that all gasoline now contains some ethanol. You do not want to let any amount of ethanol to sit in your heli. It will gum up your carb and will corrode aluminum. My heli's are ready to go after 5 months of storage using this method.

I use camper for the simple reason it doesn't have any oder while transporting in my car or working on it in my house.
I run 40:1 Amsoil.

I have mostly used camper fuel and a 65/1 ratio of Amsoil Saber 100/1 synthetic oil - now with over 200 flights. Burns clean (keeps me happy) an no smell (keeps thelittle lady happy).

GREAT TIP--!!!!

BeltFedBrowning.....NOW that is the BEST advice i have heard in a long time....i will def. run camper fuel at the seasons end!!...........

SIDE NOTE to Pinecone...i am no expert,but i have also heard that high octane burns hotter,i could be wrong,but that is what i have been told.

IF I AIN'T FLYIN' - I'M PROBABLY BUYIN'

Wow! First thing I notice is all the different oil ratio's. They are all over the map from 32 - 100 to 1. I guess there isn't a ratio that's set in stone. What ever works best for you. How did you all arrive at the mixture ratio you are using?

I though the idea of running campers fuel at the end of the season is an awesome idea!

I just received a new Hanson 3D max and Al said DO NOT run camper/Colman fuel. it will void the warranty and it can detonate and damage the eng.


lower octane fuel burns faster
higher octane burns slower

there are a few guys at our club that use Colman fuel/ amsoil saber and octane booster because the Colman has lower octane rating than reg gas
they swear by it?

With amsoil Saber I'm told you can run oil mix as high as 100 to 1

I'm going to do what Al at Hanson recommends

here is a quote from the hanson break-in sheet

1) Use quality non synthetic 2 stroke oil at the ratio of 4 ˝ oz per gallon with 87 octane gasoline for the first gallon of fuel to seat the ring. Cycle the engine up and down and avoid prolonged loading while you determine your correct gearing and needle settings for your application. Your patience during break-in will determine your engine life. Use of low octane Coleman type fuels will VOID THE WARRANTY.
2) After the first gallon, you may run 3 ˝ oz per gallon or around 32:1 of quality synthetic oil. We prefer Klotz R-50 or Amsoil Saber You might be able to run less oil, but testing has shown that there’s little increase in power as opposed to the increased protection from heat with the extra lube

CRASH! GLUE! REPEAT!

Don't just look at the ratios. Note that they are closely related to the brand/type of oil.

A special synthetic oil such as Amsoil Saber 100:1 can be ran comfortably in my experience at 65:1 (as I run) but may even do so at higher ratios, but I have not tried it at higher ratios.

Do you have any links to these tests?? I have not seen them.

That is a quote from Hanson motors It came printed with the new 3D max I just got.. Its not me saying it just repeating it

I can forward the email that Al sent me with this statment if you like PM me you address.

Just so there is equal representation, the "other" engine modifier,Toxic Racing Motors, DOES NOT have a problem with camper fuels. This is from the break-in procedure from the TRM thread on Helifreak:

Quote 
Fuel Requirements

This motor is designed to be operated on low octane fuel. High-octane fuel is not recommended as it will not add any power and may in fact reduce the available power that motor can produce. Much testing has been done using “camper” fuels. These fuels are the same as what is burned in camp stoves and are marketed under the names Coleman and Ozark brand. This fuel burns much cleaner than gasoline, has virtually no odor, gives essentially the same power as gasoline and has a long shelf life due to not forming varnish “going bad” as stored gasoline will do. Needle settings are nearly identical to those used with gasoline fuel.

Like everything else in life, the answer is usually somewhere in the middle.
