Oil

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.

Yes - good to use. Shell confirmed on a bobstheoilguy thread that Rotella T4 still contains 1200ppm ZDDP.

@Windsurfnut Excellent. I'll stay with that then.

 

Appreciate it
