Pioneering 0W-8 Engine Oil Technology: A Closer Look at ENEOS X Prime
As vehicles continue to evolve toward greater fuel efficiency, ENEOS remains at the forefront of lubricant innovation. A recent workshop demonstration highlighted our X Prime 0W-8 oil technology, showcasing its real-world application in modern vehicles like the 2025 Toyota Camry hybrid, which achieves an impressive 48-52 MPG partially thanks to our advanced lubricant technology.
Industry Leadership in Ultra-Low Viscosity Oils
For over a decade, ENEOS has been leading the development of 0W-8 oil technology through close partnerships with original equipment manufacturers (OEMs). Our expertise was instrumental in establishing the JASO GLV-1 specification – the Japanese Automotive Standards Organization’s benchmark for ultra-low viscosity oils. Not only did we help create these standards, but our X Prime 0W-8 oil exceeds them in key performance metrics.

Technical Excellence Through Innovation
ENEOS X Prime 0W-8 stands out for several reasons:
- First 0W-8 oil to establish comprehensive performance standards through extensive OEM engine testing
- Exceeds both ILSAC GF-5 and API SN performance specifications
- Delivers superior engine protection despite its ultra-low viscosity
- Fully supports manufacturer warranties
- Optimizes engine performance and longevity
Protection Through Technology, Not Viscosity
A common misconception about ultra-low viscosity oils is that they might not provide adequate protection. However, our X Prime 0W-8 achieves its protective qualities through advanced technology rather than thick viscosity. The oil is specifically engineered to provide optimal protection during the critical cold-start phase, when engine wear is most likely to occur.
This is achieved through our proprietary blend of high-quality base oils and specialized additives, ensuring that modern fuel-efficient engines receive the protection they need without sacrificing efficiency. When compared to traditional higher viscosity oils (such as 0W-50 used in high-performance applications), the 0W-8 appears noticeably lighter but delivers the necessary protection through advanced chemistry rather than thickness.
Real-World Application
The effectiveness of our X Prime 0W-8 is demonstrated in vehicles like the 2025 Toyota Camry hybrid, where it contributes to achieving exceptional fuel economy while maintaining optimal engine protection. This real-world performance validates our decade-long investment in ultra-low viscosity oil technology.

Availability and Compatibility
ENEOS X Prime 0W-8 is readily available through authorized distributors and retailers, including NAPA Auto Parts stores and online platforms. For vehicle compatibility, we recommend checking your owner’s manual or visiting the ENEOS website for a comprehensive list of compatible vehicles.
As engines continue to evolve toward greater efficiency, ENEOS remains committed to developing innovative lubricant solutions that meet and exceed the demands of modern automotive technology. Our X Prime 0W-8 oil represents not just a product, but a milestone in automotive lubricant technology, setting new standards for performance and efficiency in the industry.
