Bar's Products 4405 Hy-per Lube Zinc ZDDP Engine Oil Supplement - 11 oz

The Bar's Products 4405 Hy-per Lube Zinc ZDDP Supplement is a concentrated petroleum-based oil performance booster designed to restore vital zinc and phosphorous protection to modern engine oils. This 11-ounce treatment contains ZDDP (zinc dialkyldithiophosphate) and extreme pressure additives that help protect critical internal engine components.

Key Features:

• Contains ZDDP zinc and phosphorous EP (extreme pressure) additives for enhanced protection
• Protects flat tappet camshafts, lifters, pushrod tips, pistons, and valve train components
• Stabilizes motor oil to prevent viscosity and thermal breakdown
• Reduces friction and wear, especially during cold starts and start-up conditions
• Clinging action lubricates bearings and internal parts where conventional oil fails
• Makes newer low-zinc oils compatible with older engine designs
• Helps eliminate dry starts and extends engine life

This concentrated supplement is especially beneficial for classic cars, vintage vehicles, air-cooled engines, and any engine with flat tappet camshafts that require higher zinc content than modern oils provide. The high-performance formula ensures cooler running temperatures and longer-lasting engine protection.
