Frequently asked questions about ENEOS 0W-8, ENEOS history with 0W-8, and information about the technology about it.

Why has 0W-8 oil been created?

Lower viscosity in general represents a shift in vehicle maintenance for modern automotive technology. This shift is a direct result of requirements for Japanese automakers to reduce environmental impact, and one of those methods has been reducing oil viscosity to increase fuel efficiency. 

Primarily developed for Hybrid Electric Vehicles (HEV), Plug-in Hybrid Electric Vehicles (PHEV) and Battery Electric Vehicles (BEV) with thermal gasoline engines, this oil is increasingly becoming a requirement for high efficiency vehicles.

ENEOS has been working on 0W-8 oil in conjunction with Japanese automakers for over ten years, and has been selling 0W-8 in Japan for over three years.

What benefits does 0W-8 have other than fuel efficiency?

Low viscosity oils in general, but especially 0W oils have rapid lubrication when engines start, resulting in quicker starts and faster protection of engines. For this reason, engines with 0W oils start and coat engines faster during colder weather, but they also protect better during warmer weather.

ENEOS in particular uses our R&D expertise working in developing Japanese automotive technology with worldwide manufacturers to provide extremely high quality product with advanced engine protection.

This viscosity is very low, how does it protect engines?

Using our expertise working with Japanese automakers to develop modern oil technologies, we have developed the specifications for 0W-8 oil (JASO GLV-1) that will protect engines,by ensuring, despite its lower viscosity, that metal components do not come into contact with each other.  This oil is equivalent to levels stipulated in the GF-6 specifications of the API (American Petroleum Institute).

In ENEOS X Prime 0W-8 JASO GLV-1 Fully Synthetic Motor Oil, our product uses high quality synthetic oil blended with premium additives in just the right mix to provide superior protection without sacrificing efficiency.

What vehicles require 0W-8 oil?

Toyota and Mazda have been the first to confirm vehicles in production for North America that require 0W-8 motor oil. These models include: 

Mazda 2 Hybrid 1.5 (2022 and newer) 

Toyota Vehicles

Toyota, a forerunner in hybrid technology, has many fuel efficient models that require 0W-8: 

  • Yaris 1.5 Hybrid (2020 and newer)
  • Yaris Cross 1.5 Hybrid (2021 and newer)
  • Yaris Cross 1.5 Hybrid AWD (2021 and newer)
  • Corolla 2.0 (2023 and newer)
  • Crown 2.5 AWD (2022 and newer)
  • Grand Highlander 2.5 AWD Hybrid (2023 and newer)
  • Grand Highlander 2.5 Hybrid (2023 and newer)

Many other vehicles will be entering production that require 0W-8, and updates will be made as we are able to provide them.  Details>

What is ENEOS’ role in creating 0W-8 oil worldwide?

ENEOS has been working on 0W-8 oil in conjunction with Japanese automakers for over ten years, and has been selling 0W-8 in Japan for over three years. 

ENEOS’s influence extends beyond product development. As an R&D specialist for Japanese automakers, ENEOS helped develop the JASO GLV-1 specification, which is currently the only 0W-8 oil specification. Performance benchmarks for JASO GLV-1 are equal/equivalent to the levels stipulated in the GF-6 specifications of API.

We bring key learnings from these efforts to ENEOS 0W-8 JASO GLV-1 Motor Oil. This standard is crucial for the compatibility and performance of lubricants in newer vehicle models.

What is JASO?

The Japanese Automotive Standards Organization (JASO) plays a crucial role in setting automotive standards within Japan, a process that significantly influences the quality, safety, and performance of vehicles and automotive components. JASO is responsible for establishing a range of standards that cover various aspects of vehicle manufacturing and maintenance. These include engine oil specifications, such as the viscosity and performance requirements crucial for engine lubrication and protection, as well as standards for other vehicle components like electrical systems, transmissions, and braking systems. By defining these standards, JASO ensures that automotive products and vehicles in the Japanese market meet consistent and high-quality performance criteria, contributing to the reliability and safety of the automotive industry in Japan. 

JASO is part of the Society of Automotive Engineers of Japan, similarly to the Society of Automotive Engineers (SAE) in the United States.
