Description Pennzoil motor oil exceeds the toughest industry standards based on ILSAC GF-6 and API SP and is engineered to help prevent sludge and other damaging deposits in your engine. It provides a balance between reducing frictional losses and protection against harmful engine wear by getting between moving parts to prevent friction. No other leading motor oil provides better wear protection than Pennzoil motor oil (based on Sequence IVA wear test using SAE 5W-30). Pennzoil SAE 5W-30 is a synthetic blend oil, formulated to provide protection against the harmful effects of stop-and-go driving, and low-speed pre-ignition (LSPI) in modern turbocharged engines.
