Pennzoil makes case for clean with new oil

摘要

Pennzoil is making a case for clean with its new Pennzoil Ultra motor oil, touting the oil's goal to keep the engine close to factory clean, including those on the racetrack.rnMotor Age editors were part of the group given a look at the new oil, which hit shelves March 1. The company reports that Ultra cleans out up to 35 percent more engine oil than its Pennzoil Platinum, and exceeds manufacturers' standards for cleanliness and protection, according to Robert Sutherland, Pennzoil technology manager.
