Pennzoil Vs. Valvoline: Which Brand Is Superior?

When you buy an automobile, your manufacturer recommends using a specific type of oil. It’s because only the correct type of oil can protect your engine. However, you may find many oil brands on the market. Among them, Pennzoil and Valvoline are the most common oil brands.

You may need clarification on Pennzoil vs. Valvoline. And you also try to guess which is best for quality and value for money. Fortunately, you have come to the right place because here we will give a solution to this problem.

About Of Valvoline

In 1866 Dr. John Ellis founded Valvoline to discover the lubrication of crude oil properties. This discovery is most important for the steam engine development and internal combustion engines. This is the reason that makes Valvoline the first motor oil manufacturer.

Only Valvoline offers the first all-climate motor oil, meaning hot and cold ratings. In other words, this is the first engine oil suitable for winter and summer. Also, Valvoline manufactures its own base oil as well as additives.

Specifically, you can only find good reviews of these Valvoline brands. So it’s more impressive, and most repair shops use this Valvoline.

About Of Pennzoil

Pennzoil is an ancient name because it was established and originated in Pennsylvania in 1889. Nevertheless, for the first twenty years as a part of Standard Oil, Pennzoil worked until 1911. After that, Pennzoil became independent and started branding its own products under its name.

Later Pennzoil founded the Pennzoil Company and merged with Zapata Petroleum and Statco Petroleum. Till 1998, manufacturers and users liked Pennzoil because it met all the expectations. Nonetheless, in 1998, it became independent and achieved Quaker State Oil.

Pennzoil Vs. Valvoline Full Synthetic Oil Comparison

Valvoline and Pennzoil both oils can decrease friction in internal engine elements. They differ in weight, manufacturer, anti-wear performance, price, etc. So, let’s discuss some comparison factors between them.


Though Pennzoil and Valvoline both oils come from the USA, different manufacturers make them. The owner of Pennzoil is a Shell oil company, and Valvoline is a product of Valvoline Inc.


Valvoline oil comes with a weighing 29.9 pounds bottle, while Pennzoil oil comes with a weighing 11.9 pounds.

Temperature Protection:

Pennzoil motor oil provides better temperature protection than Valvoline oil. It’s because it holds different viscosity at extreme temperatures. Pennzoil has a higher viscosity index than Valvoline, thus keeping its density better at high temperatures. Even Pennzoil has a lower power point so it can hold viscosity better at low temperatures.


Pennzoil oil is less expensive than Valvoline oil. A 5-quart of Pennzoil oil costs $23.97, while the same amount of Valvoline oil costs $34.99.


The dynamic viscosity of Valvoline oil is lower than its competitor at both 40° and 100 °C. It indicates the lower performance at both these respective temperatures.

The Valvoline oil viscosity index is lower than its competitor. Its pour point is also higher than the other, indicating its lower performance even in cold conditions. On the other hand, Pennzoil’s viscosity index is higher than Valvoline oil.

That means its viscosity is relatively less affected by temperature increase. It also performs very well in cold environments because of its relatively low pour point temperature.

Oil Change Frequency:

Accordingly, changing Valvoline oil after every 3000-4000 mile period is best. The engine oil has a lower TBN (Total Base Number) value than its competitors. It means you should change this engine oil more frequently.

In contrast, if you use Pennzoil oil, you should change it after an average mileage of 5k to 7.5k miles. If you want to know Valvoline vs. Pennzoil high mileage: which has the best high mileage efficiency, it’s Pennzoil. The reason is that Pennzoil provides higher efficiency and higher mileage than Valvoline.

Catalytic Converter Performance:

Zinc and phosphorus are present in motor oil as anti-wear additives. As the engine oil burns, these compounds become ash, blocking the catalytic converter and inhibiting its performance.

Valvoline contains higher amounts of zinc and phosphorus for better anti-wear performance than its counterparts. Thus, its performance in terms of the catalytic converter is lower than Pennzoil.
