The Toyota Genuine Engine Oil 5W‑30 (4 L) is a premium-grade, fully synthetic motor oil specifically tailored for Toyota gasoline engines, especially those under the TNGA umbrella, as well as other modern Toyota models requiring this viscosity. It meets or exceeds key industry standards (API SN/SM/SL, ILSAC GF‑5) and is factory-approved for use in both naturally aspirated and turbocharged Toyota vehicles. With its 5W‑30 viscosity, the oil delivers excellent cold-start protection and maintains a strong lubricating film at operating temperatures, ensuring smooth engine operation, efficient fuel economy, and long-term engine durability.

Packaged in a convenient 4-liter container, this oil is an ideal choice for routine maintenance or full-oil-change service intervals. Its formulation includes robust anti-wear, antioxidant, and detergent additives that help maintain engine cleanliness, minimize sludge, and protect against wear—features that align with Toyota’s commitment to OEM-level precision and reliability. Enthusiasts note that while Toyota-branded oil is essentially a high-quality rebranded product (often Mobil-based), the assurance of factory approval and compatibility makes it a trusted option for owners seeking seamless performance and maintenance consistency.
