Pennzoil Platinum® with PurePlus Technology is a first of its kind full synthetic motor oil made from natural gas and designed for COMPLETE PROTECTION. Redesigned for modern turbocharged engines - API SN PLUS, API SN-Resource Conserving and all previous categories.
It might sound weird to some but it actually performs really well. I made the switch to Pennzoil about 3 years ago and what I can say is it made my truck run better. I noticed a big difference in cold weather. I'm no scientist or ever ran tests. So I'm just going off how I feel. I felt with other oils it can run a little "sticky" but not with this stuff
