Optimal for small and high-power engines, including JDM, European and American turbocharged engines!

• Introducing J&A's engine oil, the "STREET SPEC Series".
• This oil utilizes fully synthetic oil (VHVI base oil) and offers enhanced fuel efficiency, high-temperature oxidation stability, piston cleanliness, and catalytic converter protection compared to the traditional GF-4 standards.
• Developed with a focus on cold-start performance, the product excels in launch and acceleration capabilities.
• Furthermore, the addition of PAO contributes to efficiency improvement, maintaining a relatively thick oil film even in high temperatures, preventing viscosity reduction, and protecting sliding surfaces.
