ENEOS Announces X Prime 0W-8 Coming in 2023

As recently unveiled in the New Products Showcase at SEMA 2022, ENEOS USA Inc. is pleased to announce ENEOS X Prime 0W-8 Fully Synthetic Motor Oil will be available in Spring 2023.

The ultra-low viscosity 0W-8 was created in partnership with Asian OEMs, which requested the special formulation to meet stringent emissions and economy standards. Not only will ENEOS X Prime 0W-8 oil be supplied to manufacturers for factory fill requirements, it will also be available for oil changes by dealer networks and for DIY maintenance.


ENEOS X Prime 0W-8 is 100% synthetic oil developed in partnership with Asian automakers for use in the latest Hybrid Electric Vehicles (HEV) and Plug-in Hybrid Electric Vehicles (PHEV) where 0W-8 is specified. This currently includes vehicles from Honda, Toyota, Nissan and Mitsubishi. The oil is also suitable for Battery Electric Vehicles (BEV) fitted with thermal gasoline engines used as a Range Extender. A number of 2023 production vehicles will  require 0W-8 including the  Toyota Yaris, Honda Fit, and Nissan Dayz.*

Testing & Standards

ENEOS extensively market-tested X Prime 0W-8 in Japan for nine years to produce this optimized formula, which provides extreme fuel efficiency with maximum engine protection, while meeting the required domestic standards. As an industry standards leader, ENEOS helped establish the JASO GLV-1 specification, creating and establishing the testing methods while performing engine testing methods with OEM-provided test engines. ENEOS 0W-8 meets these new JASO GLV-1 standards. No API or ILSAC 0W-8 testing standards currently exist.


ENEOS USA Inc. will release ENEOS X Prime 0W-8 in single (1) Quart containers (part #3000-300). More information will be available closer to production.

Why OEMs Trust ENEOS

ENEOS is the largest oil company in Japan, as the “original JDM oil” we’ve been working in partnership with Asian automakers for decades. As part of this partnership, ENEOS has in-house testing facilities where we follow strategies developed with each OEM partner to meet their vehicle and performance specifications, particularly for the tighter tolerances of Asian engines that are now being seen more in European and domestic vehicles.

ENEOS provides R&D and factory fill for Asian automakers in factories around the world. This access provides ENEOS with unreleased vehicle specifications, allowing our organization to develop lubrication formulations that specifically meet (or exceed) vehicle needs. Because of these partnerships, our products are designed to anticipate future requirements beyond current domestic vehicle standards.

We like to say our obsession with quality and innovation is more than just a statement—it’s why we’ve been trusted by OEMs for almost half a century. More
