Dealing With Ultra Low Sulpher Diesel
Posted November 23, 2012 - 03:15 PM
From what I can gather, ULSD lacks the lubrication that was present in the LSD that it replaced, and that can cause problems with fuel pumps, injectors, etc. With two of the older diesels, one being the Wisconsin/Ducati which parts are almost impossible to find, I started looking for possible solutions.
In my research I turned up this independent study/test:
Based on that study, I'm thinking of using the Opti-Lube XPD. Has anyone here used the Opti-Lube products? If so, what are your observations.
Another question I have is on very cold temps. XPD is advertised to prevent gelling dawn to -20F. That should be more than enough for my location, but let's assume that for some reason it dropped -30F and my fuel gells. Will it 'un-gell' once the temperature rises to something reasonable, or would I have to take other measures?
I'm a newb to this diesel stuff, so any advice is helpful.

If nothing else I would probably change the fuel filter to remove any water that is in the filter.

I ran VW diesels for many years and they thrived on a diet of about 8 ounces of 2-stroke to a tank of diesel fuel. It is an oil that is designed to be burned, unlike 4-stroke motor oil which contains a lot of additives such as zinc which will produce a lot of ash.
For anti-gel, you want to use a product called Power Service. It comes in different grades, in white, silver, or red bottles, though not all stores will carry all varieties. White is regular strength, silver is extra strength, and the red is "Diesel 911".
Alternately, a small amount of plain old kerosene acts just fine as an anti-gel, or at higher dose to thaw gelled fuel.
Be sure to use some 2-stroke with it, as kerosene lacks lubricity. The 2-stroke oil makes up for it nicely.

I do not know anything about the additive you mention, but put 200,000 miles on a VW diesel Rabbit.
So for many years have been a believer in Power Service and add a few ounces to every can of diesel I bring home.
I never had a gelling problem, but there are several things I do to prevent it.
1. keep the tannk full so condensation does not allow water. 2. buy your fuel at tha truck stop that moves a high volume of fuel
(for same reason as 1) 3. Do not buy a lot of extra fuel that can sit in the can and collect moisture. 4. buy the fuel when you need it.
I worked part time in a truck stop here in Iowa(we get cold winters). Winter blends of fuel are blended based on the temp at the depot at the time a tanker is filled. This means if it is 34 degrees at the time the tank is loaded and the temp is 20 below that night, the winter blend could gel. This is the reason I always add power service to my fuel.
Another thing to consider if the fuel gels the paraffin can clog the fuel filter. If you ever get a gel its a good idea to have a spare filter to change. It was 60 degrees yesterday and 28 when I fired up the Ford this morning, a diesel does not have to be a problem if you just take a few precautions in cold weather.

I DO NOT RECCOMEND THIS IF THE MIX IS WRON IT CAN BLOW THE BEAD OFF.
When i worked the fuel island in the truck stop, we were forbidden to mix gasoline regardless of a drivers insistance as the truck stop could be liable if we did.

There are FAR better methods available now, and I wouldn't recommend it, but in an emergency a small amount of gas - and I stress SMALL - would be OK to use on an older diesel. I would couple that with some 2-stroke oil if I had to do it, and all bets are off on a newer, high pressure system.

My tractor holds 5.5 gal. And back when I worked in the truck stop the trucks were running around 75-120 gal.
Im not reccomending it because when your working with a small total volume of fuel the percentage of gasoline goes up astronomically with very little added.
