New type Diesel fuel - Page 4 - PeachParts Mercedes-Benz Forum

Below is the reply I just received from Mercedes Benz - Canada, in response to my original question concerning the low sulphur diesel fuel due October of this year:
=====================================
Thank you for your interest in Mercedes-Benz. Please note the 15 ppm is
expected to be fully compatible with most vehicles. A small number of
vehicles may require preventative maintenance in the form of upgrading
certain engine and fuel system seals that may not perform well with the new fuel. It is anticipated that only a very small fraction of vehicles will
be affected, primarily older (pre-1993), high mileage vehicles with original seals still in place. Please review your maintenance records to ensure that fuel system seals have been changed with recommended parts at recommended intervals. If the seals are original, we would recommend
having them inspected by an authorized Mercedes-Benz service facility,
prior to the new 15 ppm fuel becoming available.

Best regards,

oh that's "swell" news... what about biodiesel? does it have any effect on seals?

It will still outlive me, the rest of the car, and western civilization (probably in that order) with or without ULSD.

That reminds me of something I read on this site quite a while back. It was something like "When humans cease to exist and cockroaches aew 6 feet tall, they will be driving these diesel Mercedes"

I dont remember who posted it, but it was funny though

Personally, Im not going to really worry about it too much. I can understand using a fuel additive every once in a while, but I wouldnt use them on a regular basis with the new ULSD fuel.

This is I believe the first time in my entire life I've ever been even slightly relieved to be driving a gas engine car..

I bet injection pump rebuild sales go up in the next few years, and lots of good deals on dead cars too..

I wonder if a $2/qt bottle of vegetable oil will be a good lube- probably 1/2 bottle per tank. Strikes me as much cheaper than motor oil, if you buy new motor oil.

The best way to restore lubrication would be to add a lead based additive.Probably not too environmentally friendly though.

NewBenzOwner · #53 05-20-2006, 08:42 PM

ULSD has to meet a lubricity requirement, an additive has to be added at the delivery point just prior to loading on a delivery truck. I really don't think it is a concern if you use one of the many additives that are out there.
Just my .02

In my limited experience, even a little contamination with motor oil will increase your smoking.

Or you could always use 2% biodiesel as your lubrication additive. Works wonders.

From what I've read, 100% biodiesel can degrade the natural rubber seals and fuel lines in older cars. If your car is newer than '94 that isn't an issue, since those components are synthetic. I'm also fairly certain B20 doesn't cause those kinds of issues.

The old fuel injected [MB] 300s of the 50's and 60's had injection pumps very similar to our diesel ones. They are lubed by the engine oil and the plunger bores are fine with gasoline which is a solvent and not an oil in the first place.
