Driven Racing Oil HVL (High Viscosity Lubricant) is a multi-use lubricant with superior film strength. HVL features advanced synthetic base oils that provide excellent film forming characteristics. Driven Racing Oil 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. Apply to engine bearings, piston skirts, bushings, timing chains and gears, as well as oil pump gears. HVL can also be used as a chain lubricant to reduce friction and provides grease-like durability.
