New low sulphur diesel warning!

[commuter boy]

Hmm.  That may explain why Giles said he got 5 pumps in last week for overhauls and performance builds when he usually only gets a trickle.

If you put low sulpher diesel in a car that requires Ultra low sulpher diesel it will wreck the emissions equipment, it can't wreck the engine itself.

So where do you fuel up if you've got a 07 or newer vehicle?

[jimbrown618]

So I guess the bottom line is that we should be using an additive at every fillup? I was using Stanadyne but just switched to Power Sevice. I have a 97 Golf TD with 358K and have been having no problems so far...)knock on wood...).

I just decided to try Diesel Aid, seems to be working pretty good, my car always has full potential (unlike other times when it feels unusually gutless).  I bought it at a local Western Star/Sterling shop.  on little 8oz bottle treats 240ish gallons, and i put in 1/4 into a what? 12 gallon tank? :lol:

Basically, it looks like we'll be going through the same issue with diesel's in the next few years that gas engines went through with leaded and unleaded gas back in the 70's.   Two types of fuel -- the old stuff kills the catalytic converters on the new ones, and the new stuff destroyes the engines on the old ones......    :roll:     And all of us driving old diesels will keep a can of lubricity booster in the trunk, just like everyone used to have a can of lead substitute in their car for years (I still have a truck that doesn't take unleaded gas, but I'm changing it to electric drive soon).

We went though all this back in the early 90's, with the switch to low sulpher diesel. The lack of lubricity killed a few borderline pumps, mostly stanadyne and CAV rotaries. Seal shrinkage caused some leaks. The refiners added lubricity additives and the issue was mostly forgotten. Armed with this experience I would hope that the refiners would take the necessary steps to deal with the lubricity issue this time around.

I use power service.  Good stuff!  Makes my car a bit accel a bit faster by boosting the cetane too.

I'm wondering about notching my gas tank filler neck for a little hose.. so I can hook up a little spray pump (the stuff stinks...) to spray before I pump the diesel.  Hook up a washer pump... 1 pulse would probably do it right?

It would make much more sense to have Biodiesel or a blend instead of the ULSD crap; it would solve BOTH problems!  :roll:  (lubricity and lower emissions)

IN THEORY, the ultra low sulfur fuel should have enough lubricity - they have to meet a lubricity specification. If it doesn't meet that specification, then the station owes you an injection pump. But I don't think lubricity is the problem here...

I think what you all are seeing is seal shrinkage, due to there being less aromatics in the fuel. The issue is, those aromatics caused your seals to swell back in the day, and then crush themselves. When the aromatics go away, the seals shrink... but they're crushed, so now they don't seal. This is also the source of all of the "oh noes, biodiesel made my injection pump leak" stuff.

Fully rebuild your pump, go on with life, and don't touch low sulfur fuel once this happens.

Or, if you're really worried about it, use the old-school Cummins trick back from 1993. Automatic transmission fluid. Not sure how much to use, though. Don't go overboard, as you don't want to make it high sulfur - you're trying to bring it back to 500 ppm, from 15 ppm, not 5000 ppm from 500.

The low sulphur fuel DOES NOT have enough lubricity, one of my local fuel injection shops has been playing around with the new low sulphur fuel for a while now, the process they use to make the low sulphur fuel decreases the lubricity drastically.

ATF will work, 2 stroke oil works much better, as it is designed to MIX with fuel.

[burn_your_money]

How much 2 stroke oil should be added per liter?

[RabbitJockey]

run it on straight 2 stroke oil, it's cheaper

[935racer]

1 OZ to 10 gallons.

It stinks worse than diesel?   Diesel smells bad enough.    I'm used to B100, and I had to fill up a car with gasoline this week -- didn't realize what a stinky process that is.  You get spoiled using biodiesel all the time.  Although, most people think that biodiesel is what smells funny.

Here's some good reading on the low sulfer diesel. Might be slightly Biased though
