Isopropyl Alcohol

Volvo says you can run this in their cummins trucks @ 1 pint per 125 gallons to keep fuel from gelling. Can't get much cheaper for a fuel additive. Just thought I'd share =P

I would not put alcohol in your fuel. I believe alcohol is bad and there should be not alcohol in gas or diesel. It comes in pump gas, but it would be better if it didn't. When you buy those bottles of isopropyl acohol, or what ever, they have a percent. Usually they are 70% (sometimes 91%). The other 30% is water. That alcohol doesn't do you any good. I believe your fuel efficiency will go down among other things.

I reccomend using 100% pure acetone. Just put about 2 oz per 10 gallons (0.15625%). I don't have any experiece with gelled fuel, but that's a higher percent than what you said for alcohol which has WATER in it (water freezes easily). I put acetone in sometimes for better fuel efficiency and, I think, a decrease in smoke. Acetone will definitely help with the gelling and it is completely safe. Purchase it at a beauty supply store by the gallon or by 16oz bottles at places like walmart or walgreens (maybe) for pretty cheap.

You can also put gasoline in your diesel to help with the gell thing. Diesel engines can actually take a large percent of gas without harm done. About 20% gas and you are safe, so, you could try like 1 or 2 percent if you want, because I don't think you need 20%. My friend just told me about a lady that filled a ford diesel up from empty with gas and ran it for a long time. It started smoking really bad and eventually shut off, but they drained the gas and filled it with diesel and it started up and ran fine! It was still running 2 years later and then they sold it. That's pretty amazing. Usually the engine just becomes a solid block after running really fast and hot for a couple minutes.

Be careful what you are getting..

Isopropyl Alcohol that you buy from the local pharmacy that ladies put on their zits is 70% by volume meaning it is 30% water in the solution.

The Isopropyl Alcohol that you get at the hardware store like Home Depot is 99.9 % pure last I checked.

There is also an alcohol of a different animal called Denatured Alcohol.

You should also be able to get it at some truck stops for the alcohol injection on the air compressor.

This is so the air does not freeze, or at least the moisture in it.

Imagine if you could freeze air bubbles then shoot them with a slingshot.
Or put them in your drink to keep it cold.

Go in any truck stop, they sell diesel fuel line antifreeze. It is mainly isopropyl alcohol, and may contain some aromatic solvents. http://en.wikipedia.org/wiki/Isopropyl_alcohol

Acetone is a solvent and will chemically attack every bit of rubber in a fuel system.
There is no way Volvo would even mention using an additive if it was going to cost them warranty work.

denatured alcohol is enthanol made undrinkable by adding a toxic substance. http://en.wikipedia.org/wiki/Denatured_alcohol

I've been told many times that Alcohol is not good for our injectors and not to use it. Thou I do see PSD 911 does have some in it but it's used to geled fuel. That being said what does Dodge have to say as many here may be still under warranty. My self I will stay with PSD anti gel and not have to worry about it and I get extra lube for my fuel system.

Back when we had one of the fake gas shortages of the 80's when they were pushing Gasohol as our savior, they were having problems with the fuel systems; the rubber and leather parts would swell and bind in the bores causing them not to work.

It would also clean the varnish from the fuel tanks and clog the filters more often.
There was also the issue of breaking down the coating in the aluminum float bowls making them pours.

Although it was a higher ratio of Ethanol alcohol to fuel and it was not diesel I would hate to have problems with an expensive pump.

How does the alcohol react with the lube additives in your tank?

You're just asking for trouble by mixing your own concoctions to put in your tank! And DO NOT use gas. Gas does not lubricate injection pumps or injectors. Just buy an approved anti gel fuel additive and follow the directions on the label. For added insurance, use blended fuel.

Just a bit newer than dirt.
While our Dodges trucks may not have Fine Corinthian Leather seats or interiors, leather is used for pump pistons, seals and shaft packings. While probably most of the newer designs have synthetics most of the old carburetor accelerator pumps were leather. When you used Gasohol for any period of time the piston cup would shrink so it would not fit tight in the bore so the result would be when you step on the gas the engine would stumble. It also made the float bowls porous and the gas would seep through the metal.
But I did like the smell of the blend.

If you read the instructions and follow them concerning the diesel fuel antifreeze, it will not harm anything in the fuel system.
The addition of acetone will degrade anything rubber , including the injector o-rings.

Those of us old enough to remember the 1st "gas shortage" were all driving vehicles with leather parts in them. It wasn't ethanol that caused all the problems, they were using methanol as an additive too. It is much more corrosive.

TDR recommends against any alcohol or acetone product use. They say both will cause fuel system damage.

Vorige week was ik in Rotterdam en mijn vrienden wilden wat spanning. Ik zocht een site voor sport- en casinowedden en ontdekte posido. Er zijn verschillende aanbiedingen en tips speciaal voor spelers in Nederland. Ik vond het leuk omdat het een gezellige sfeer gaf tijdens het samen kijken naar wedstrijden en we er samen om konden lachen.
