Your car was originally spec'f for a 15w-50 or 15w-40 oil w/ ZDDP levels in the 1100 to 1300 ppm range

there are several oils available that fit the bill
If a particular oil company refuses to provide ZDDP levels I'd avoid their products

Mobil is widely available and reasonably priced, here is the Mobil 2019 spec sheet, remember you are looking for 15w40 or 15w-50 and Phosphorus and Zinc levels in in the 1100 to 1300 ppm range, anything outside those values is not what was originally spec'f and the further out the worse for the motor longevity.
