Importance/lack of lubricity in USA diesel fuels
...as presented in a recent Bosch workshop held in Sacramento Ca... Note that *80%* of California diesel fuels sampled fell OUTSIDE the recommended levels of proper lubricity for Bosch injector pumps!
This is a PDF file... Page 15 deals specifically with the VP-44 - but it's ALL excellent stuff!

Good reading for anyone SERIOUSLY interested in their VP-44 injector pumps - and my reason for posting in THIS group...
(EDIT)
Moderator - thanks for moving this to the proper forum - nice to get exposure in BOTH groups, since it does apply - but THIS is where I had meant it to go.) ;D

[quote author=DF5152 link=board=4;threadid=15373;start=0#144486 date=1054475810]<br>without having to read through evrything do they recomend an addative?<br>[/quote]<br><br>You hafta read between the lines and use common sense with some of this stuff - neither Bosch OR Cummins are likely to ever recommend a fuel additive, since they would have NO control over what owners might use or HOW they would use it - it's a liability issue they simply WON'T touch, even though they obviously are WELL aware of the problem!<br><br>Every injector pump shop owner/worker I have talked to directly, or read posts of on boards like this one, are not quite as strictly bound by legalities, and INVARIABLY, *they* will STRONGLy recommend use of a major brand additive such as Stanadyne or Power Service to avoid well known pump failures due to poor diesel fuel lubricity - they WILL shy away from recommending other types of additives, such as automatic tranny fluids and such - stick with the stuff MADE SPECIFICALLY for added diesel fuel lubricity, and you won't go wrong! ;D ;D

Re:Importance/lack of lubricity in USA diesel fuels
This is a very interesting topic. I would like to try some of this "Hammerdown" product in some engines that I know are smoking due to carbon build up on the ends of the injectors. I would like to hear what other people are using as an addative to help lubricate and/or reduce carbon build up.<br><br>Does this lack of lubrication go hand and hand with the lift pump problems that seems to be so common?

"Does this lack of lubrication go hand and hand with the lift pump problems that seems to be so common?"<br><br>Well, as they say, "opinions are like bellybuttons..." ;D<br><br>*I* think lift pumps fail for a variety of reasons, and for those reasons directly affected by lubrication, yeah, better fuel lubricity would undoubtedly help - but for other types of failure, probably not...<br><br>Still, providing better fuel lubricity when even Bosch has claimed it's low on most fuels available today across the US seems a logical place to start...

Gary,<br>I thought I had read sometime back that the Power Service had alcohol in it. I can't confirm but do you have info on it.<br>tia<br>wk

Re:Importance/lack of lubricity in USA diesel fuels
Dunno about the alcohol - might be worth dropping them a message to find out - but then, you'd pretty much need to do that with any brand you pick - I have no particular loyalty to the PS stuff, only that in a past comparative test for lubricity involving a half dozen or so top brands, PS came in second, and was only slightly behind #1, which was Stanadyne - I can get the PS stuff cheaper and easier at the nearby Walmart, so it makes sense to me...

Gary, do you have a cite on that lubricity test? I'd like to take a look at it. Been using Shell Rotella DFA, but if it's worthwhile to change. . . . <br><br>Been trying to find such lubricity tests on the web, but most of the manufacturers don't seem to have specific lube characteristics listed.

You can find the comparisons on this site www.dieselpage.com , also the best price I have found on the Stanadyne stuff.<br>wk

Re:Importance/lack of lubricity in USA diesel fuels
Sorry - it's been several years since I read that comparison - and that was a major reason I settled on the PS stuff, plus the ease of local purchase. I'll do a search to see if I can find that, or hopefully, and even later product comparison to post or provide pointers to.
AND, I suppose I'm blind, but *I* didn't see ANY comparison of fuel additives on the site pointed to up above - they seem to be a Stanadyne dealer, and may have good prices, but no comparison of effectiveness between various competitors *I* could see...
