Lubricity

There is no insight here, just calling it as I see it. You wanna waste your time on this go right ahead.

Yes b/c 2 or 3 Thousand hours on a pump or better yet a motor is a moot point but if its a waste of time why come back to the thread

The problem with the change in lubricity is that the high pressure fuel pumps (HPFP) on VW common rail systems are failing before 2K hours. The NHTSA has opened an investigation on the problem.

Anys links you can post to this problem would be helpful?coobie

TDI ISSUES - HPFP Cases

That's one of the reasons we decided not to replace our 99.5 TDI with a new one. Another reason was the poor(in my opinion) fuel mileage so a gasser made more sense.

This makes for some interesting reading on additives. It is an independent study concerning this matter:

I've been mute about this whilst I was trying to learn something about it. All this thread has done is confused me. So this morning I ran into a friend who deals with selling and maintaining equipment with diesel engines. He simply said I can take you and show you examples of using additives versus not using additives and there will be absolutely no question about the value of the additives. Known him all my life and totally trust what he says. I went straight to CarQuest and purchased some PS additive.

Interesting comparative study with good controls on commercial bias. Findings are also quite interesting with regard to ranking of available commercial diesel additives and breaking some of the Amsoil myth as well as that of other popular additives.

I have a couple of questions. 1) Does anyone know if Kioti has any concerns about 2% soy based biodiesel (adding biiodiesel to 2% final concentration with road diesel). 2) The study was done with a special batch of unlubricated ULSD however that is not actually what any of us use regularly as any road ULSD diesel has at least some lubricant added before sale. I wonder what the test results would be using the various lubricity enhancers with that real world fuel rather than "worst case" unlubricated fuel? ?Additive effect ?Synergy ?Anatagonism

I've heard from a reliable source that John Deere has had problems with injectors that they traced back to the fuel used. Apparently it was a biofuel although I don't know what percentage. The problem I heard was that the bio part of the fuel was made with a combination of plant and animal matter. The plane matter was supposed to be ok but the part that was made from animal parts is supposedly what caused the injector failures. I've tried to find links to it on the web but no-go.

Has anybody else heard of this?

Sure. Reported in JAMA a few years ago. Cholesterol plaques cause stenosis of the injectors. :laughing:

I have been using a blend of biodiesel ever since the U.S. went to ultra low sulfur diesel. I use 20%-50% depending on temps. (bio gels easier) My diesel mechanic showed me the difference between an engine with bio and one without. It was astounding! I will be running bio or an additive until they change diesel fuel again.

And according to the Journal of Creative Cardiology it's OK to do an injectoplasty--BUT DON'T TRY A STENT!

I just sit back in air-conditioned comfort and realize that I'm too old to die prematurely.

At the risk of introducing another whole topic of discussion, I wonder how all this lubricity discussion applies to those operators who use furnace fuel oil in their tractors. Some claim furnace oil is identical to road diesel, except for the dye (ie, =off road diesel), but others question this assertion.
Do any of you really KNOW how furnace oil stacks up against regular pump diesel? Or maybe furnace oil is too variable/unpredictable in composition to be trustworthy for motor fuel use?

KIOTI stance is 5% Bio-Diesel. Bio-diesel does have a shelf life so it is not good for "Hobby Farmers". Be reminded, soy based bio-diesel has a tendancy to asorb water!!! We all know how great that is for a fuel system!

A friend used it for years in his smaller ford diesel tractor. He finally sold it and went bigger but told me he never had a problem. I did question it like you and just go to the pump for my fuel.

 

[rd_macgregor]

Here furnace oil is about $0.20/l cheaper than diesel fuel, so a savings of about $0.75/USgal. That would add up to quite a big savings over the course of a year UNLESS it damaged the engine! I hate paying a road tax for fuel that's burned only in my fields and woods.

This thread is not any less dumb now than when it started.

That's your second dumbest post on this thread. Give up and crawl back into your hole.
