Cummins/Powerstroke/Duramax

After years of testing and reformulating inside our own turbo program, FIS Turbo Pre-Lube is finally available to the public. Built from hydrotreated heavy paraffinic petroleum distillates, this refined blend was engineered through countless teardown inspections and performance trials to solve one problem: dry starts that kill turbochargers before they ever see boost. FIS Pre-Lube creates a strong, clean oil film that clings to thrust faces, bearings, and oil passages through assembly, storage, and startup. It stays put where other oils drain off, resists oxidation, and dissolves instantly into your engine’s oil system at first fireup.
