Each 5/8 oz. HVL | High Viscosity Lubricant packet from Driven provides enough lubricant to pre-lube bearings or timing sets in most engines. The packets provide excellent pre-lube for timing chains and piston skirts. The non-foaming product mixes with the break-in oil and extends the film thickness during the break-in process. HVL’s unique, high-load-carrying capacity formula provides proper flow and protection during engine assembly and start-up. The lubricant replaces the use of motor oil and tacky lubes during assembly, and it will not harden or cause parts to become sticky during storage.
