SAE J 1704

SAE J 1704 is an American technical standard that defines the requirements for motor oils with a viscosity of 5W‑30, intended exclusively for gasoline engines of passenger cars. Within this standard, wear resistance, oxidation stability, corrosion protection, and the ability to maintain an economical operating mode over a wide temperature range, including cold start, are evaluated. Oils that meet SAE J 1704 are suitable for modern 4‑cylinder and V‑type gasoline power units, including those with turbocharging, which require low viscosity to reduce fuel consumption while still maintaining the necessary level of protection under high loads. The standard provides compatibility with catalysts and after‑treatment combustion systems, so such oils can be safely used in vehicles with three‑way catalysts without requiring special SAPS‑restrictions. When choosing XENUM products bearing the SAE J 1704 designation, you receive guaranteed engine protection, stable performance in any climatic conditions, and compliance with manufacturers’ recommendations.
