Do you use heet? - 87Bielenberg - 01-20-2013
Does anybody use Iso-Heet in their tanks? I have heard that its not good to put any alcohol in diesels. What can you use for water and condensation in the tank? What about acetone?

Regular unleaded gasoline nowadays is 10% ethanol, and in my '83 300D I routinely run a WVO mixture which is 5% RUG, so that means I'm using 0.5% ethanol in my fuel --about 13 ounces of pure ethanol per every 20 gallons of fuel. Doesn't seem to harm the engine or the rubber fuel lines.
I also add 25 ml of acetone per every 20 gallons of fuel. But at 75 ml per 20, the engine runs noticeably rougher.
StarTron enzymatic diesel fuel treatment, is excellent for dealing with the algae which water lets grow, and I add it to my fuel as well. It only takes about 75 ml of StarTron per 20 gallons of fuel. Around here, StarTron is sold at boating supply stores, every diesel boat owner on Puget Sound uses it.
Power Service Diesel Kleen, sold at every truck stop and WalMart, is said to have ingredients which help remove water. I use about 1-1/4 quarts (1125 ml) of Diesel Kleen per every 20 gallons of fuel, but that's probably overkill, 500 ml would probably suffice. In Butte in January you will want to use the winter formula of Diesel Kleen, in the white jug (the silver jug is the summer formula). Check around for price discounts on larger jugs and drums than what you find on the shelf at the local Flying J or Town Pump or whatever they call themselves nowadays. I buy mine at a local oil filter and hydraulic lines shop, cheeeeeep.

25ml per 20 gallons is a drop in the bucket

I know it's a tiny amount, but that *is* what I have found.
I mix my fuel in 4-gallon batches.
5 ml acetone (along with 100 ml turpentine) = dissolves polymerized canola oil really well, no loss in performance (actually, slight improvement, due to the cetane raising power of the turpentine).
15 ml acetone ( + 100 ml turpentine) = roughened idle.

It suspect that ATF will absorb some water. I know it does when agitated. I've seen milkshake ATF sit in a container for weeks without the water ever separating.
Running a tank of straight ATF every once in a while should keep a small amount of water in check, but it's probably not best to try in a Montana winter since it's got a low cetane rating.

Straight ATF? Who does that? wouldn't that be ridiculously expensive?
I think I will put some acetone in. Just a little. What about that Sea-Foam stuff, anybody use it?
RE: Do you use heet? - raysorenson - 01-21-2013
Nah man, it's not too cheap if you get the crap from wal-mart.
Most all folks running ATF use filtered waste ATF. I'm sure somebody out there only uses the new stuff though
RE: Do you use heet? - sassparilla_kid - 01-21-2013
Seafoam FTW!!!! I love that stuff
RE: Do you use heet? - Tmadia - 01-21-2013
I have had good luck with Sea Foam on gas engines. I have yet to use it on a diesel.

+1 for gas engines, esp. on older carbon caked ones...SeaFoam is pretty awesome for gas.
I have also used Star Brite (StarTron) in my boat and it seems to work well. That thing has 500+ gallons of fuel and still fires right up when I warm her up once a month. I bought it with the same fuel it has in it right now and have only used about 50 gal or so in the 8+ years Ive owned it (only made a few trips to the shipyard and back aside from the monthly maintenance). I am curently in the process of pumping the tanks out into some drums so I can replace the black iron with some poly ones and the fuel is really clean looking. That fuel is likely 20 years old and still no signs of algae, etc.

You could also add a fuel water separator in line to the injection pump and drain off any water every once in a while.
