ENEOS X PRIME is a New Premium Engine Oil developed with reference to the voices of ENEOS service stations nationwide. In order to further improve customer satisfaction, it was developed with a focus on “ride comfort,” which is our unique index, in addition to fuel efficiency and acceleration performance. In addition to meeting the performance requirements of the latest engine oil standards (API SN, ACEA C3), the ride comfort has been greatly improved by reduced engine noise and vibration resulted by significantly reduced friction.
