Oil that is Available with the most ZDDP

[e anderson]

What is the Oil the has the most ZDDP in it , Rotella and Delo have been modified as of January 2007 with less Zinc.
One of the oils I can come up with that has the most Zinc in it is the "brad penn" oil , are there any other oils that are good for older "flat tappet" engines or are there additives to add to the new oil. I am looking for Zinc levels above 1400 , thanks.

Mobil1 states that their 15w50 Full Synthetic has a much higher level of AW additives for older engines. http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_15W-50_.aspx

This stuff should be easier to find than other products.

There is a used oil analysis in the DIesel section (used) From a Ford 7.3 that used Vavlvoline PBX, has some pretty high ZDDP numbers. I think it CI4+ for sure though.

Don't forget that too much ZDDP can foul your plugs if you're burning any oil. 0.11-0.13% is about as much as you'll need to protect the cam/lifters.

There's a chart in this thread https://bobistheoilguy.com/forums/threads/any-one-use-diesel-oil-in-racing.62357/ in a post by 63Avanti that lists ZDDP content in a variety of oils. Not ALL oils, but a fair number of 'em.

Wouldn't it be nice if the oil mfrs showed a VOA on the side of each container. Shouldn't be that hard to do, you'd think.

Yeah, keep dreamin'.
