The Toyota Genuine Engine Oil 20W‑50 (4 L) is a conventional mineral-based lubricant designed for use in older Toyota gasoline and diesel engines with wider internal clearances—such as classic Corollas, Hiluxes, or Tacomas. Its high-viscosity formula provides a thick and stable oil film, helping maintain compression and offering reliable protection during high heat and heavy load conditions. Ideal for engines that experience oil consumption or operate under strenuous environments, it helps reduce friction and manage engine wear effectively.

This engine oil meets API SL for gasoline engines and CF for diesel applications and includes a robust additive package with detergents and anti-wear agents to combat deposits, sludge buildup, and oxidation. Available in 4-liter packaging, it’s convenient for full-oil-change intervals or topping off older vehicles. While modern engines require lighter, fully synthetic oils, the Toyota 20W-50 is a factory-approved choice for preserving performance and longevity in classic or high-mileage powertrains.
