ZDDP was invented in 1941 by Lubrizol.. Lubrizol is the company who formulates and produces the Joe Gibbs offerings, to include our DT40 offering.

Jake, I am still planning on buying a case of this DT40 (5W40) from Charles for my yearly oil change next month.

Can you post a VOA? Or at least tell me the levels, in PPM, of your Zinc and Phosphorus? I'm hoping it's about 1,100 PPM for both, and on par with my current Mobil 5W50. Thank you.
