The only oils that stay in suspension in alcohols are plant based oils High quality castor which is very hard to find now and I am experimenting now with rapeseed AKA canola and it is looing promising.
 
I have yet to see an MBTE only fortified racing fuel in the USA and to my knowledge very little is used
VP, NUTEC and Phillips 66 make race fuels with MTBE/ETBE in them. Some have lead in them, some do not. I am sure there are others.
You can also buy pure MTBE from PAR to dope race fuels with.
 
Okay

A question for you have you ever bought bottles of octane booster?

how many points can you raise the ocatne with the booster? it is NOT infinite

and as a second question what is the octane boost additive made of?
 
If I remember correctly most off the shelf octane boosters raise octane about 1/10th of 1%. The are composed for the most part of MMT, but I have seen some that are base on Toluene.
 
I have to go and check current labels

But I remeber toluene being only a carrier for MBTE, ETBE or a blend of the two that used to be listed as "propietary ingredients" and the most you could hope for on a good day with a non MBTE or other oxygenate enhance fuel was 2 to 3 points with the oxygenate already in the fuel your figure sounds about right
 
The one that had Toluene as the booster was made by PJ1. Not sure if it is still made.
I have never seena over the counter octane booster that used ether mtbe or etbe, but I havent looked to hard as I have no interest in "boostin" crap pump fuel for race applications.

They work a bit better than that from my recollection. I used to have to use it in my old BMW R100RS if I was going to get up in the mountains. The thing would detonate like crazy until I put the octane booster in it, then it ran as it should. Every once in a while I would get a tank of low octane premium, and would have to use it in the flatlands. Kept a bottle in my tank bag for those occasions.

That was then

It used to work because back then not all OTR gasoline was doused so liberally with low grade MBTE at the refinery. Yes it is true american gasoline is just about the WORST in the world. Even my Czech and Croatian friends lament the poor quality and stink of US pump gas
 
The Proccess of Dissolving

The particles of dissolving substance, the solute, are attracted by the molecules of a solvent. These attractive forces may be van der Waals forces of various strengths. If the attractive forces of the solvent for the solute are strong enough to overcome the attractive forces that hold the particles of the solute to each other, the substance will dissolve. So basically if you have a solute which is in this case is Methyl alcohol it will dissolve in the stronger solvent water. The same also applies for water and acid, like other polar solvents the donation of electron pair donors are essential for solvents and solutes.

The problem which I explained and the reason I call it methanol is that the conversion to MBTE from methanol and isobutane and or propane is not permanent and degrades rather rapidly


Hi,

Okay, that's reasonable. now I know why you're putting Meth and MTBE in the same drawer. However It has been bugging me a little that methanol should be a degradtion product so I looked up the primary degradation products.

Anyway MTBE does not degrade back to methanol but rather to the folowing substances which are the primary degradation products: "...mainly tert-butyl formate (TBF), tert-butyl alcohol (TBA)" with smaller quantities of other compounds but however nowhere could I find methanol listed as a degradation product for MTBE.

So I reckon the problems you've had with MTBE fuels is that they also probably contained Methanol/Ethanol or else it just has something to do with the extremely poor petrol quality you people have to live with over there.

Bye

There has also been problems of Marine engines....2 and four stroke...having issues with the Ethanol in the fuel.

Not real sure whether the 2-stroke marine engines have additional problems with E-85 or E-10 or whatever it's called, but one big problem with these ethanol-gas blends in boats is that the alcohol is apparently messing with the FRP (fiberglass/polyester) fuel tanks. I'm not sure whether it's dissolving the polyester resin ... or dissolving crud that has built up in those tanks over the years ... or what. But I've heard some tales of some FUBAR carburetors and engines in boats with FRP fuel tanks running the ethanol gas...

One last one if you mix a pint of alcohol and a pint of water....you don't get two pints of liquid, but like 1 3/4 pints of liquid.....try it and see.


Have you been adding water to your Bourbon?

I prefer my Whisky straight :givebeer:

Take water at the end of the evening - this staves off hangover :hmm3grin2orange:

By way of a digression - a chemist told me that Hair of the Dog - drinking to fix a hangover - works because it stops the body absorbing nasty methanol for a while in favor of the new supply of ethanol. Anyone care to comment?

I would hope there's no methanol in booze...methanol (wood alcohol) will make you blind -- literally! :cool:

I think the quantities involved are so small as not to be an issue. Supposedly it is inevitable that a very small quantity of methanol is produced in any brewing process. Fortunately I have no experience of the after effects of drinking meths :givebeer:
 
Water methanol works SLICK

My favorite use is silly amounts of over boost pressure in non intercooled turbo diesels
