Best ZDDP additive?

[4WD]

STP oil treatment is advertising ZDDP on the bottle. Saw it a NAPA Canada.
Oops. Brought up a two year old thread when I searched ZDDP.

Honestly think a person would be better off skipping anything like the STP or Lucas , Dura Lube or Slick 50 products. These companies were actually taken to court and paid some hefty fines some years back for not being able to show any proof what so ever that there is anything in these products that will improve or do what they claim. Dura Lube was found to be nothing but 5w30 weight oil. Slick 50 was found to contain solid particle PFE teflon. STP was proved to be little more than thick gear oil similar to many Lucas "quick fix" products.

Yeah, I always see folks with beaters buy these things - along with a bottle of 5W20 …

The STP Oil Treatment isn't even gear oil. It's a 50 SSI OCP VII with only a trace of ZDDP. (150-200 ppm Zn/P) It actually dilutes the ZDDP concentration down.

It actually dilutes the ZDDP concentration down.

Couldn’t have said it better myself.
