ZDDP Oil Additive 444-544

According to Phil Singher, the Napa Fleet Plus oil has the proper additive package (zinc and phosphorus) for our engines. Blackstone labs has tested this oil quite a few times as well.

NAPA oil is the same as Valvoline, except that it is a lot cheaper. The ZDDP additive is too expensive. The Universal Fleet Plus only costs $15 for a gallon, nut it is only available in 15W-40.
