Re: Rizlone ZDDP additive
I have been adding 1/2 a bottle of ZDDP w/ each oil change. I did a quick calculation and determined 1/2 bottle w/ whatever level of zincphosphate present in current Mobil 1 formulation would bring the total to about 1200 ppm.
Ofcourse, I have no idea as to what is really in ZDDP... Only could go by what they claim. |
