Jet-A is a kero based product. I tested it's lubricity at about 650 HFRR, which is terrible. The maximum spec (lower is better) for diesel is, I think, 450. Adding Stanadyne lubricity additive did not bring Jet-A into range. But adding 200 to 1 TCW-III along with Stanadyne lubricity additive brought Jet-A to 255, on the HFRR.

I've used that ratio for 20 years without any issues what so ever. Although I will admit the oil did not always completely burn in some devices (stationary low RPM generators) under low load and left an oily soot in the tailpipe. I bring that up because Catalytic Converters and DPF's may have trouble with higher oil concentrations. I never had any issues with Cat's. Never any issues with EGR or EGR coolers. The Cummins motorhome, Jetta, Mercedes, Dodge truck and other VW's never experienced any troubles of any sort.
