Adding lube oil to diesel fuel for lubricity ?

[edhackett]

The addition of motor oil to the diesel fuel increases the proportion of the particles smaller than 2.5 microns. These small particulates form around the metallic components of the oil, such as zinc and calcium. These particulates also tend to be solid, as opposed to the typical aggregated particles. These small, solid particles are the most toxic.

While on the surface it would seem burning your waste oil is a good idea, it is really a bad idea from a health aspect.

I would not take everything in that thread on Cumminsforum.com for absolute truth. The Mopar1973Man is putting out a lot of misinformation and seems to have an ill-researched hatred for diesel fuel additives other than 2 stroke oil. He looked up some MSDS sheets, awarded himself a chemistry degree, and has deemed it his duty to lecture, over and over, about how bad they are for your IP and injectors. (with no proof) Meanwhile he pumps up 2 stroke oil, talks relentlessly about its benefits, with no downside, at all. (with no proof) Just a waord of caution, although I really don't see any harm in 2 stroke oil, even in HPCR fuel systems.

hes not selling anything so he gains some credibility in my book.

Well, Bush isn't selling anything, either. Is he gaining a lot of credibility just because of that?

Use a diesel fuel additive that provides additional lubricity, for additional lubricity. Stanadyne is one of
the few (only ?) DFAs that has some OEM approvals.

..follow-up note.... a 'ggod' DFA provides a cetane boost, lowers gel point, and increases lubricity, and the Stanadyne site has some comparisons between different products. You can get additives that just increase lubricity, or just lower gel point, etc., where engine and equipment suppliers also provide products, like John Deere, Fleetguard, etc.

The most popular additives seem to be whatever is at Walmart.
