Is Penzoil a Shell Product?

[VanKaden]

Penzoil is indeed a Shell product, being Shell's passenger car engine lubricant brand in the United States. Established in 1889, it is one of the largest lubricant suppliers in the U.S. Engine Oil Selection: Naturally aspirated engines have relatively moderate requirements for oil quality and can use mineral oil or semi-synthetic oil. If the car owner has a higher budget, fully synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, demanding higher oil performance. They require oil with better fluidity, preferably fully synthetic oil. Brand Selection: When choosing a lubricant brand, if long oil life is a priority, Mobil lubricants can be selected. If engine cleaning capability is important, Shell oil is recommended. For lubricants requiring strong oil film toughness, Castrol can be chosen. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell oil with strong cleaning capabilities can be selected.
