Since the OM352 (and 366s) hit the street, diesel fuel has changed, it previously had sulfur that acted as a lubricant in the injection pumps. In order to clean up the air, recent diesel is ultra low sulfur meaning injection pumps are having a rough time. Some folks are adding a bit of two stroke oil to the fuel but from what I have read it really doesn't do the trick. One of the diesel forums did an independent test and it looks like Optilube seems to be rated well. There is also a claim of cetane boost and possibly it cleans the injectors. I bit the bullet and bought a jug of it and plan to be running it in my mogs. Anyone else using Diesel treatments?
