Increases Film Strength: Over 75% of internal wear occurs during the first few seconds of engine startup. Hy-per Lube Oil Supplement leaves a protective film that will not run off on all internal parts including cylinders and gears, providing complete protection against start-up wear.

Lowers Temperature: All lubricants can foam. Foaming restricts the oil's ability to dissipate heat which increases operating temperature leading to premature wear. Hy-per Lubes anti-foam capability reduces foam, helps extend engine life, and lowers operating temperature.

Prevents Thermal Breakdown: High performance additives ensure against viscosity and thermal breakdown. Hy-per Lube's 100% petroleum-based formula provides protection between oil changes and can extend oil life by up to 50%.

Reduces Friction: Friction modifiers increase engine lubrication in new and old engines. Reduced friction extends engine life, provides more power and can increase fuel economy. This is a benefit for new and old engines, and will not void any warranty.
