Driven Racing Oil 01606 HR3 15W-50 Synthetic Street Engine Oil - 1 Quart

Driven Racing Oil HR3 15W-50 Synthetic Street Engine Oil is specifically engineered for modified old school muscle cars, big block engines, and high-performance street applications. This high-zinc formula delivers the anti-wear protection that older push-rod and flat-tappet engines require, while the synthetic base provides superior cold-start protection and thermal stability compared to conventional oils.

Key Features:

• High Zinc Content: Elevated ZDDP (Zinc Dialkyl Dithiophosphate) levels provide essential anti-wear protection for flat-tappet camshafts and older engine designs that modern low-zinc oils cannot adequately protect
• Advanced Camshaft Protection: Features the same proven wear protection chemistry used in Joe Gibbs Racing's NASCAR Championship-winning engines
• Military-Grade Storage Protection: Incorporates oil additive technology developed for the U.S. Military to prevent rust and corrosion during storage and periods of inactivity
• Synthetic Formula: Provides enhanced cold-start protection, better high-temperature stability, and improved flow characteristics compared to mineral-based oils
• 15W-50 Viscosity: Ideal viscosity for long-stroke engines, high compression builds, and engines with looser clearances typical of older performance engines

Ideal Applications:

• Classic muscle cars and hot rods with modified engines
• Big block and stroker engine builds
• High compression naturally aspirated engines
• Supercharged and turbocharged marine engines
• Air-cooled performance engines
• Any flat-tappet camshaft equipped engine

Each bottle contains 1 quart (946ml) of oil. HR3 is the perfect choice when you need modern synthetic protection combined with old-school high-zinc additive packages for serious street performance and engine longevity.
