Some Brad Penn oil on the way
Patrickt,
I ordered a case of 15-40w from the Oil Warehouse today. They confirmed that their stock of Brad Penn oils was from the revised formula (changed in 2008) with the appropriate levels of zinc (1500ppm) and phosphorus (1400 ppm) for a flat tappet cam. They communicated that they sell a lot of the Brad Penn oils for flat tappet cam motors.
Short of sending some of this new oil to be tested for zinc and phosphorus levels, is there an API specification rating on the product that I should be looking for? From some of the forum contributions, I understand that a rating like SE might provide the appropriate levels of zinc and phosphorus but a rating like SJ or SM would not. Are there specific API ratings we should be looking for to get the prevent appropriate levels of zinc and phosphorus? Does a specific rating guarantee these levels or that the specific rating does not prevent higher levels of zinc and phosphorus (meaning that you need to review the product specifications)?
