The Best ZDDP Oil Additive & Cam Assembly Lube
ZDDP Performance from ZDDPlus
ZDDPlus is the original, best researched and documented cam wear solution available.
ZDDPlus™ is an oil supplement that contains very high concentrations of the well-known additive ZDDP (Zinc Dialkyl Dithiophosphate), which has been the primary EP (extreme pressure) ingredient in all quality motor oils for over 70 years. Learn more why ZDDP is critical for your vehicle in our FAQs
ZDDP Perfect for Classic Cars
Why Is ZDDP Essential for Classic Car Engines?
Put simply, modern cars and camshaft systems are built differently than the masterpieces of the 1940s–1970s. Today’s vehicle manufacturers use roller lifters instead of flat-tappet lifters because of emissions and profit concerns. Roller lifters have lower friction variables, so modern oil formulations contain minimal ZDDP. They’re great for today’s everyday automobiles, but lead to serious risks for classic car engine longevity.
A big part of driving a vintage vehicle means preserving its factory parts and original performance specs. Having a source of additional zinc and phosphorus in classic car motor oil is vital.
What is ZDDP?
ZDDP stands for zinc dialkyl dithiophosphate. This compound has significant engine protection characteristics, especially for high-performance motors. ZDDP coats flat-tappet lifter and cam contact points with a durable shield that protects their ductile underlying metal. To guarantee long and healthy engine life, keeping these contact points safeguarded against friction, wear and damage is critical. ZDDP is considered the gold standard for collectors’ engine protection.
Superior in Every Way
Zinc and phosphorus in modern oils amount to a mere 600 or 800 ppm. By adding the proper amount of ZDDPlus™ you will be able to give your camshafts and lifters the correct amount of ZDDP they were designed to operate with, ensuring an optimum coating for long-lasting engine performance.
- Far superior to modern engine oil, with better viscosity control than racing oil.
- More available anti-wear ZDDP than diesel oils.
- Proprietary blend of ZDDPs for maximum protection
- Carefully balanced for premium results.
