I haven't worried about the low sulfur fuel that came out 4 or 5 years ago, but now I think maybe I should have. I did a search and there seems to be a real problem with some of our older diesels (pre 1995 or so) without some type of hardened components in the injection pumps.

It's hard to tell what the truth is. A while back, someone here called several refiners, and seemed to get the answer that their fuel isn't a problem, but I'm not sure they were talking about the older diesels. One of the additive makers, stanadyne, indicates that 70% of the fuel they tested fails lub tests, but who knows what tests those are.

It seems that lots of truckers and farmers are using additives.

Is it just as simple as adding 4 or 5 ounces of new motor oil at every fill up, or is that too simple.

Have you been using an additive, and what type. Has anyone had an injection pump failure, possibly caused by the new fuel??

Thanks
