Serious engine protection for your high-performance ride! Valvoline's VR1 Racing Motor Oil in SAE 30 weight is specifically formulated for engines that work hard - whether you're hitting the track or cruising the streets. This stuff is packed with ZDDP anti-wear additives that provide incredible protection for flat tappet camshafts and other high-pressure engine components. The enhanced friction modifiers actually help improve horsepower by reducing drag, while the anti-foam system keeps the oil working consistently even under extreme conditions. It's recommended for gasoline engines and can handle full or partial alcohol fuels too. This case of six 1-quart bottles means you've got enough for oil changes plus top-ups between changes. Perfect for classic cars, muscle cars, race cars, or any vehicle where you want that extra level of protection. Valvoline has been trusted by mechanics and racers for generations - this is the real deal for keeping your engine running strong!
