Legal fuel?

Try This Stuff

Propylene oxide is a highly toxic flammable chemical compound. It is an epoxide having a molecular formula C3H6O. Other names include methyloxirane and 1,2-epoxypropane. Propylene oxide has a single chiral center, and thus has two enantiomers. The material commonly available is a racemic mixture of the two enantiomers.

Propylene Oxide. This fuel additive in general is safe to handle except for two possible conditions, which under certain cir***stances could well be dangerous these are the effects cause by the fuel coming in contact with copper/alloy containers, fuel tanks, etc., or by rust particles getting in the fuel by accident, for example from a rusty container, or from rust from damaged can top cap.

The best increase in power is obtained by some 5 percent as additive, as above this figure the gain does not increase in proportion, like the other additives, but in fact tends to decline, so stay at the 5 percent mark.

I just spoke with a fuel distributor that sells to farmers and I'm looking at getting a storage tank for clean gas without alcohol for off road use only. Has anyone else tried their local farmer or marina to get clean gas? Much cheaper than race fuels.

PROPYLENE OXIDE

Propylene Oxide's primary contribution to the combustion process centers on it's high heat of vaporization. As we discussed in Part Four of this series (NKN June 1995), this high heat of vaporization means that, as it passes from a liquid to a gaseous state in the carburetor, it absorbs a significant amount of heat and, thus, cools the incoming fuel charge significantly, making it denser. While Propylene Oxide brings along some of the oxygen it needs for it's own combustion, it also takes additional oxygen from the carburetor air. It's specific energy is slightly less than that of gasoline, so don't expect any help there. It's combustion products are C02, CO, and water vapor. As you can see from the graph, there is no measurable performance difference between the base-line fuel and the sample containing 2% Propylene Oxide, slightly above the threshold of detectability with the Digatron meter. However, by increasing the concentration to 10% by volume, well above what even the most bumbling tech man should be. able to spot, we begin to see the effect of improving the charge density on the low end. This effect diminishes as RPM increases, probably because this higher air velocity through the carb dramatically improves the atomization of the gasoline and the resulting chilling of the incoming charge.

Conclusion: Yes, using Propylene Oxide may help the low end performance or used in sufficient quantities. But unless there is no fuel tech at all, you can't get away with running enough to get any improvement.

That stuff is a BIG NO NO !!!!!!!!!

the hot ticket....

hey mike....

after reading your post i called the local fuel supplier that i used to fuel my dozer w/red. they have just what we are looking for. they try to keep it on hand although it sells out at times. it contains no ethanol/alcohol. they said the price is .10 cents higher than the daily unleaded price.

great thought.... all the time it was right under my nose.... give me a shout if you want me to pick you up some.

Marine Dock Fuel

I just called Morrison Marine Fuel Dock in Seattle, Westlake Avenue,
and their fuel 87 Octane, never contains Ethanol. $3 something a gallon.

I will buy my fuel there.

Good call Mike. Thanks.

So from what I'm reading here, its the pump gas part of the fuel rule that needs to be changed.
Its obvious that we do have good fuel options, they just don't all happen to come from a standard gas station (pump gas). Some are just more pricey then others.
I know of several racers that use av gas, and I'm one of them. But it still comes from a pump! but its a truck not a gas station.

Pump Gas

Gene,

You're right. The words "Pump Gas" have been in the rules forever and those words are now most likely not relevant any longer.

We can now buy a "Can" of race fuel and as long as it passes the "Meter" it
should be a legal fuel.

Anyone, is this correct?????

Thanks for the offer Bill, I have a friend that farms and I bought my race gas from him last year, so I'm covered.

You're welcome

Last year "pump gas" was close to $4 a gallon, I never paid more than $7.25 a gallon for race fuel (vp 93 or sunocogtx 260). most of your boats use about 2 gallons per class all weekend. It works out to the cost of a few beers all weekend and you have less chance of bad fuel wrecking a motor which costs far more.

Just my 2 cents.

I have a question regarding this wonderful fuel situation and the almighty meter.

Last week we purchased ethanol free gas from BP/Amoco. I asked the station manager if he was certain that the fuel contained no ethanol. He assured me there was no ethanol in it. Guess what happened when we had our fuel tested? We finally found some fuel in the pits that passed the almighty meter (thanks Dianne & Pete) but were instructed to keep it in the shade as the meter will show it illegal if it gets to warm. We had some visitors there when this happened and they were very interested in the concept of "clamp on and go" racing. When they saw the fuel debacle and heard all the suggestions of "go to this airport and get av gas" and "go to the local speedway and find a race fuel dealer" they were instantly turned off with the idea of spending money on boat racing.

This is the J, AX, and KPro class. It shouldn't be so darn stressful trying to find gas so the kids can go have fun.

My question,....
What fuels can we run in Joey's OMC's without doing any damage?
Is there a maximum octane they will tolerate?
Which is better, AV gas or race fuel for the OMC's?
Am I the only one who's girdle does a wheelie over this darn fuel meter/ethanol B.S.?
