Lucas Racing-Only high performance motor oil is blended with an exclusive additive package that includes lubricity agents and anti-seize agents. It helps control drag like a zero-weight oil and protects metal like a heavy, multi-viscosity oil. This lubricant contains ZDDP levels far above older SAE API standards to safeguard critical engine parts, such as flat tappet lifters and camshafts. Lucas Racing-Only motor oil stands up to higher oil temperatures for longer oil life and less metal fatigue. It guards against oil cavitation, produces less drag for increased horsepower, and is compatible with methanol or racing fuel. This product also uses Group II and III synthetic base oils, so its higher lubricity will ensure faster acceleration and maximum protection for your racing engine. Choose synthetic, semi-synthetic, or mineral oil in the weight recommended for your application.
