I've used Power Services product that is supposed to prevent gelling in the winter in dozer, excavator, dump truck, and tractor. It does work as advertised to prevent gelling so it can't be all snake oil. I've never seen increased mpg, restored power, or any of the other over the top claims. If I had access to fresh, quality bio-diesel that would be my additive of choice for better lubricity.
Agreed, lubricity is a good target. I also have fear of water and removing any chance of moisture getting into the tank and through the HPFP
Your second fuel filter removes water (between the fuel pumps).
