That is exactly why I use emulsifying additive.salmon slayer said:I for one choose to emulsify. I am no expert on HPCR systems but I do know from experience with heavy equipment in cold climates that water DOES pass through the seperators. Even after three in a series I have seen enough water accumulate to freeze a line solid.
Some folks may consider it a contradiction to add an emulsifying additive to a fuel system that includes a seperator. I see it more as a two pronged approach.
