New type Diesel fuel
Does anyone know what effect the new type of Diesel fuel that's due to come out in a few months is going to have on our older Mercedes diesel engines?
The way I understand it the current type of Diesel fuel will be discontinued, at that time.

Essentially it just has lower sulfur, so lubrication properties of the fuel will go yet lower, so it may be a good idea to use a bit of fuel additive on each fillup, like 1/3 or half a bottle of powerservice or something, just to add the extra lubing for the barrels in the injection pump. Thats what I will probably do...you can also just put in one of those little "pints" of 2 stroke oil that you'd use with yard equipment, or a half a quart of clean motor oil....anything like that would help the lubricity. I'll be doing one of them....probably whichever I have on hand at the time (likely general gasser motor oil)

It's ok to just put a little regular motor oil in the tank? Doesn't really matter which? Wonder if that will increase smoking...

If its a light gasser motor oil (clean/new) and a quart or less I'd guess that the smoke difference would be extremely minimal, but it'd help overall lubrication....maybe I'll dump a quart into mine next fillup to see how it reacts.....it could be a while though, my next fillup is in about 2.5-3 weeks at my current severely-reduced amount of driving.....

by light, do you mean stuff like 5w30 or something?
what about Lubro-Moly's "Diesel Hi-Test"? Does it provide any lubrication? |

guys, the new ULSD will meet ASTM D975 standard which specifies lubricity and that standard has to be met for #1D and #2D. Lubricity standard is defined by 520 microns HFRR maximum.
if you're truly concerned about this, toss in a little biodiesel - - 2% is more than adequate.

Well actually Lubro-Moly is probably a bad idea because it's generally not sold in stores, and I don't want to buy crates of that stuff online so i have some for every fill-up...
a can of Hi-Test treats 20 gallons - that's one full tank. Costs 5 bucks each... another expense to pile on... Maybe there's a more economical alternative that does the trick... |

most of the mainstream additives enhance lubricity. I suspect Power Service DFS (white bottle) is the least expensive and can be purchased at Wallysmart, Autozone, etc. it's pretty cheap in the 96oz size. They added a bit of Methyl Soyate at the last re-formulation.

Does anyone have reason to believe this is an actual concern? I have not heard anything to indicate that we need to do anything different with ULSD. AFAIK, these engines are doing just fine in europe with ULSD. I just don't think the sky is falling yet.

The ultra low sulfur diesel has been available in kalifornia for a while now and it has no effect on the Bosch injection pumps. The pumps used in our old MBs are lubricated by engine oil not by diesel oil. No additives are needed just clean fuel. According to the veteran MB DIY Marshal Booth, these pumps were even used in some gassers which has no lubricative properties at all.

A member on another Mercedes forum, where I posted the same question provided a link where the characteristics of the new Diesel fuel are described.
http://chevron.com/products/prodserv/fuels/diesel/faq.shtml I just read that link and this does not sound good at all, especially the section where Chevron states that there is a good chance that rubber seals throughout the injection system may dry up and start leaking. Apparently lubricity IS NOT the problem, but dried out "O" rings and seals are. Chevron also state that fuel additives will not help. This is not good. Phil

Which is exactly why I said before that switching from dino oil to synthetic may result in oil leaks, since the dino oils have some aromatics that swell the seals whereas the synthetics do not.
But back to the original question... This article seems to suggest that while perhaps it's not so much the pump that needs lubricating, but it's the seals that will shrink and leak. Now, many will probably say - replace your seals... That's time and $$$. Eventually. But for now, perhaps additives may solve that problem. |

This would be a good time to go into the snake oil business.
