Stay up-to-date with the latest developments as the launch of PC-12 nears. PC-12 builds on API CK-4 and FA-4 oils introduced in 2016, which improved stability, aeration control, and fuel efficiency. It will further advance oil technology with lower viscosities, better oxidation stability, enhanced wear protection, and improved aftertreatment performance.

As our team works to dial in our new formulations to meet the new standards, you can rest assured that Phillips 66 will provide high-quality engine oils that won’t just meet the standards — they’ll exceed them.
