Lucas Oil 10683-3 is a conventional 10W40 motor oil engineered specifically for hot rod and classic car applications where flat-tappet camshafts and older valvetrain designs demand extra protection. This high zinc (ZDDP) formulation helps guard against wear at the cam-to-lifter interface, a critical concern in vintage and performance engines running conventional oil.

Key Specifications:

  • Viscosity: 10W40
  • Oil Type: Conventional Petroleum
  • Zinc Content: High Zinc (ZDDP) additive package
  • Container Size: 5-quart jug
  • Quantity: Set of 3 (3x5 qt jugs)
  • Total Shipping Weight: 30.15 lbs

Formulated with Lucas Oil's proprietary additive blend, this motor oil is built to reduce friction and wear on high-load components common in hot rods, muscle cars, and classic vehicles. The high zinc content provides an added layer of protection for engines not equipped with roller cams, helping extend component life and maintain consistent oil pressure across a range of operating temperatures.

Each set includes three 5-quart jugs, giving you enough conventional 10W40 oil for a full oil change with extra on hand for future service intervals or top-offs.
