Add Sulfur to Diesel fuel?

[Ken45101]

I would not put anything but a modern fuel additive or some quality 2 stroke oil into a modern engine.

Probably good advice. However, I think the main issue is ULSD in older engines that were designed and built for older diesel fuel which had higher sulphur content and provided lubrication that those engines expected. Like our ten year old tractors. Those are not modern engines designed to work with ULSD.

Would I mess around with adding stuff to my newer equipment? NO!

But it may be a good idea for me to add some outboard 2 stroke oil to my ten year old tractors.

I am not an engineer.

1*What do you think about adding sulfur to diesel fuel? You can buy sulfur as a soil supplement,
2*I wonder if it would work? How much to add per gallon?

1*Bad Bad Bad IDEA.
2*Nope.

Ahhhhh, no.
3*Why would you want to do that? :confused2:

3* That's a good question.

Ditto what Happyman said. Not all "sulfur" is the same AND it eats steel.
4* If your goal is lubricity, purchase an additive.

4*Go with an additive especially approved/formulated for diesel .
2 cycle oil , Hydraulic oil , transmission fluid,motor oil and such are not approved for adding to diesel .

5*The lack of sulfur in the fuel is NOT what is causing less lubricity.. It is the process of removing the sulfur that caused less lubricity..

5*Therefore adding sulfur to deisel does not change or increase lubricity.

6*Adding soil amendments to your fuel would have disastrous consequences; your engine would immediately be destroyed.
7*I keep a cocktail for lubricity of 2 parts supertech 2 cycle and one pat white power service premixed in one of the 2 gallon safety tanks and add ~2oz. per gallon of diesel. I don't know it makes that much difference, but it does sound quieter, and seeems to keep the water separator dryer.

6*Rite on.
7*You don't want/need a cocktall or some sort of snake oil mix when an additive especially approved/formulated for diesel will do the job.

8* Sounds like 2 cycle oil will be my additive as I already have some generic brands that I do not use sense I started using Stihl oil in all my saws and trimmers.
9*Another thing, I have heard the old timers say they would add a little unleaded gas to their fuel back in the day. Was that for better combustion or just to keep it from gelling in cold weather?

8*Why not use the correct additive instead?
9*Gasoline is the worst thing you can add to diesel .

10*I have heard of automatic transmission fluid being added but cannot confirm or recommend.

See 4* above

11*And while you're at it, find an old flashlight battery and scrape some of the zinc off of it too for the oil. It's good for the lifters. Yipes! You're heading for trouble.
Come on guys.
12* Quit trying to be your own chemist and use a proper additive if you're going that route. :thumbsup:

12*Good advice.

LB,

If you read the Dieselplace thread I referenced earlier you will find that some of those "especially approved (by whom?)/formulated for diesel" additives ARE snake oil and accomplish nothing beyond reducing your wallet. Some actually REDUCE the fuel quality.

Super Tech Outboard 2-cycle TC-W3 engine oil was shown to make an improvement.

I gotta figure out how to post like this... you can answer twenty questions with one post.
Oh, there are worse things than gasoline... I saw two engines that had well fracturing gel accidentally added into the fuel tank...

2 stroke oil has been proven to work for years. It is also not detremintal to the newer HPCR engines. And atleast its actually designed to be part of combustion.
Be very wary of any additive that says its for use in diesel AND gas engines...

The Dieselplace thread I mentioned said that use of 2 stroke oil in 2007 and newer engine was untested and might cause problems. Personally would not use it in newer engines, they are designed to run with ULSD. It's the older engines that apparently are at risk with ULSD and need help.

There is no benefit to doing that. Suphur doesn't add lubricity to fuel. Sulpur in the fuel isactually harmful because it results in the formation of suphurous acid that can damage engine parts.

The process that removes sulphur reduces the lubricity requiring the use of lubricity additives to the fuel to meet the ASTM spec for diesel fuel. If you don't think there is enough lubricity in the fuel, treat your fuel with an additive that adds lubricity. Personally I think it's a waste of money.
But never add sulphur to your fuel.

Supposedly, use of B5 (dino diesel with 5% bio) gives enough lubricity to diesel fuel and is recommended by VW in their new TDIs. It's what I'm using now in both the TDI and my tractor. Frankly, I think the lubricity think is a red herring. I just like using B5 because it foams a little bit less and makes stuffing the tank easier, and it's a tad of "green". Locally, it's been the same price as D2 for the last 2 to 3 months. Before, it was about 2 cents/gallon higher.

At estate sales, I occasionally run across ATF that marked down 75% (on the 3rd day) and buy it and put small amounts in my tractor's B5 fuel. In the refinery, if we didn't need the ATF distillate for ATF, it was diverted to the diesel pool. This was before ULSD. Don't know whether the distillation end point spec has been changed to disallow this for ULSD. Doubt it. Could be harder stuff to remove the sulfur from though, as it's the heaviest diesel component.

Benz actually recommended some use of ATF in diesel in their old diesels. When we had our 240D, I'd blend some of the estate sale ATF into its fuel. Don't use it in the TDI though.

Yall must either live in hippyville or a near a huge city, where do you buy these various blends of biodeisel? I have never seen it anywhere i go in GA or SC?
