Lucas Oil 10679 Hot Rod & Classic Car HP Motor Oil SAE 10W-30

Lucas Hot Rod & Classic Car HP Motor Oil SAE 10W-30 is engineered specifically for muscle cars, showroom vehicles, classic cars, and trophy cars without catalytic converters. Manufactured with the highest quality paraffinic base oils, this oil is fortified with a unique high-performance additive package designed to deliver maximum protection under the most severe operating conditions.

Key Features:

• High Zinc, Molybdenum & Phosphorus Formula – Elevated levels of these anti-wear agents create a tougher, thicker additive film for superior protection of flat-tappet camshafts, lifters, and other critical engine components
• Improved Film Strength – Strengthens the oil film between cylinder walls and piston rings to reduce wear and slow oil consumption
• Lower Oil Temperatures – Helps dissipate heat more effectively, extending oil life and reducing thermal breakdown
• Minimizes Metal Fatigue – Reduces micro-welding and surface fatigue on highly loaded engine parts
• Pressure Improvement in Worn Engines – Helps restore and maintain proper oil pressure in high-mileage or worn engines
• Wide Temperature Range – Excellent cold-start properties combined with the ability to withstand high operating temperatures
• Fuel Compatibility – Compatible with methanol and all racing fuels
• Oil Compatibility – Mixes safely with synthetic and conventional (non-synthetic) motor oils

Lucas 10679 is ideal for use in vintage, classic, and high-performance engines that require elevated levels of zinc (ZDDP) for flat-tappet camshaft protection — a critical need in older engines designed before modern low-zinc oil standards. Suitable for racing applications.

Note: Not recommended for use in modern passenger cars equipped with catalytic converters.
