"“We at Pennzoil take great pride in the fact that Shell scientists work as a team with Ferrari in the Trackside Laboratory at each Formula One race, at the famous Ferrari factory in Italy and at Shell’s R&D facilities in the United Kingdom and Germany,” said Luis Guimaraes, VP, Shell Lubricants, Americas. “The technical partnership with Ferrari ultimately provides us with an environment to test new lubricants in extreme conditions. This gives us a better understanding of what will deliver improved protection, performance and efficiency in everyday engines, which is evident in the development of the new Pennzoil UltraTM.”
If it's good enough for a Ferrari, it's good enough for my Nissan.
Absolutely no oil temp change noted from Nissan Ester, and I wasn't expecting any.
Also a $20 rebate, and a chance to win a Richard Childress Racing Camaro SS. What's not to like...........
