The Lubrication Specialties Inc HSS64Z is a 64 oz engine oil additive formulated to remove stiction buildup from gas and oil engines while reducing internal friction. Stiction — sticky friction caused by oil deposits on engine components — leads to increased wear, reduced compression, and power loss over time. The HSS64Z addresses this by cleaning engine internals more thoroughly than standard additives, restoring compression and freeing up power. It is intended for use by fleet technicians, diesel specialists, and automotive service professionals working on high-mileage or hard-working engines where oil deposit accumulation is a recurring service concern.
The HSS64Z is suited for use in both gasoline and oil engines across a range of applications including light-duty trucks, heavy-duty diesel equipment, and high-hour commercial engines. It is added directly to the engine oil and works through normal engine operation to dissolve and flush stiction-causing deposits. Service technicians typically apply it as part of a preventive maintenance interval or when diagnosing symptoms of stiction-related power loss, hard starts, or excessive engine noise.
Designed for use in gasoline and oil engines where stiction-related deposits and friction reduction are service concerns. No specific model or system compatibility data was provided by the manufacturer for this listing.
This additive is installed by a qualified technician into the engine crankcase oil with the engine off and cooled to a safe handling temperature. Follow the manufacturer dosage instructions based on total oil capacity before adding to the sump. Do not overfill the crankcase beyond the maximum oil level mark. Dispose of used oil and additive materials in accordance with local environmental regulations.
