Baller 2Valve Posted September 9, 2019 Baller Share Posted September 9, 2019 I certainly don't want to start an oil debate, but does Shell Rotella 15w40 still have sufficient levels of ZDDP to safely use in my solid lifter 2002 PCM motor? We're still skiing through October but starting to think about winter maintenance. 2Valve Link to comment Share on other sites More sharing options...
Baller Windsurfnut Posted September 9, 2019 Baller Share Posted September 9, 2019 Yes - good to use. Shell confirmed on a bobstheoilguy thread that Rotella T4 still contains 1200ppm ZDDP. Link to comment Share on other sites More sharing options...
