Multi-Use Lubricant With Superior Film Thickness and Tack. Driven HVL is formulated with our GP-1 Pennsylvania Base Oil For Ultimate Cling & Tack
High viscosity assembly lubricant (HVL) provides a tenacious yet fluid film to protect reciprocating and rotating components during assembly and initial break-in. This non-foaming product mixes with the break-in oil and extends the oil film thickness during the critical break-in process. Fortified with ZDDP. Apply to engine bearings, piston skirts, bushings, timing chains and gears, as well as oil pump gears. HVL will not harden or cause parts to become "sticky."
