I'd suggest filtering your waste drain oil and add a quart or two of the filtered drain oil at each fill-up. That should solve any lubricity problems.

Actually, uls diesel has a lubricity spec, which low sulpher or any other diesel fuel never had. The lube pump additive is included in the fuel by the supplier. I lost the web sites, but if you Google for ULS Diesel there is a ton of info out there.
