Pennzoil PZ-SYN1030 5QT Synthetic Motor Oil, 10W-30, 5 qt

PurePlus® technology is our patented, revolutionary gas-to-liquid process which converts natural gas into a first-of-its-kind, high quality full synthetic base oil. Because our base oil is made from natural gas, it is clear with fewer of the impurities found in crude oil, the start for many other traditional and synthetic motor oils. To that pure, clear base we add our high performance additives to create Pennzoil® Platinum with PurePlus® Technology, motor oil designed for complete engine protection, without compromise. Pennzoil® Platinum full synthetic motor oil with PurePlus® Technology keeps pistons up to 30% cleaner than required by the toughest industry standard1 and keeps your engine cleaner than any leading synthetic oil.
