Description

X PRIME 5W40 OIL

This oil is Made in Japan.

ENEOS X PRIME SP/C3 brings the most advanced technology and highest quality specification standards in premium engine oils especially formulated for a wide range of modern gasoline and diesel engines.

This “made in Japan” newest and highest quality range in ENEOS product line delivers an excellent driving experience through a significant reduction in engine noise and vibration and guarantees the car’s original performance, with excellent fuel efficiency and acceleration.

ENEOS X PRIME SP/C3 engine oils have been engineered with the ENEOS proprietary technology of WBASE oil.

The WBASE offers the world’s highest quality level with top range viscosity index, greater than the conventional fully synthetic base oils. This means that the viscosity change of those oils associated with the engine temperature change is substantially smaller. Therefore, the oil can offer low viscosity and low flow resistance in the engine already at low temperatures and during cold start. In addition, since pressure-viscosity coefficient is lower than conventional base oils, it can greatly reduce the viscosity resistance especially at high pressure points.

ENEOS X PRIME SP/C3 exhibits exceptionally high acceleration performance improved by up to 5% compare to conventional products. ENEOS X PRIME SP/C3 also demonstrates a significant friction reduction in a wide range of temperatures from low to high due to unique compounding technology of additives. By reducing the noise and vibration inside the engine, the ride comfort has been greatly improved compared to conventional oils.

ENEOS X PRIME SP/C3 with C3 specifications are known for superior performance in modern vehicles. ENEOS X PRIME SP/C3 are designed to meet the stringent requirements of the latest
engine technologies, providing excellent protection and cleanliness. Advanced formulation from Japan ensures optimal lubrication and minimizes deposits and sludge buildup, contributing to extended engine life and improved fuel efficiency. ENEOS X PRIME SP/C3 is a top choice for high performance automobiles.
