Can you provide any COMPARATIVE data to justify the use of Penzoil synthetic in ,y beloved SRT?
In response to the need from Chrysler, Pennzoil® introduced the new Pennzoil Ultra™ 0W-40 synthetic motor oil, created alongside Chrysler Group engineers specifically to keep SRT engines running clean. The advanced, co-engineered formulation is the result of months of collaboration between Pennzoil scientists and Chrysler Group engineers to develop a motor oil that provides the performance that SRT owners have come to expect from their high-tech engines. Pennzoil Ultra™ 0W-40 is the motor oil Chrysler recommends for use in all SRT engines, exceeding the stringent Chrysler MS-12633 specification.
