Pennzoil full synthetic both are for different engines. Even so, to enhance the performance and productivity of your engine, they serve different elements. Though they come from the same brand, let’s see how they differ.


Both motor viscosity is the same oil. However, Pennzoil’s 100% synthetic molecular formula helps ensure complete protection for optimal engine performance. It’s because synthetic blend oils mean it’s semi-refined oils. That means it’s not fully refined like full synthetic oils. That’s why they contain much higher levels of contaminants.

During high-speed performance, it helps to keep oil temperatures low. At rising temperatures, it works incredibly well. Quaker State Motor Oil, on the other hand, provides smooth oil film protection from start to finish while maintaining viscosity.


Both engine oils are suitable for using gasoline engines. But for your diesel engines, you can use Pennzoil. If you have two different engine type cars, you can use Pennzoil for both vehicles as the same engine oil. It’s because it will be trouble-free.

Alternatively, you can use the Quaker State as a regular user. The reason is that it has synthetic ingredients, which can make it a highly efficient engine oil.


Adequately, both engine oils contain a synthetic formula to increase your engine capacity. Due to using them, you can get increased engine performance. Most importantly, Quaker State engine oil has mixed materials, synthetic or conventional. In contrast, without any additives, Pennzoil engine oil comes from complete and pure synthetic oils. So, without any doubt, you can get better performance from this fully synthetic oil than a mixed oil.


Pennzoil supports API SN PLUS, the latest motor oil specification designed primarily for turbocharged engines, to protect engine performance. Similarly, due to automakers’ requests, this oil comes and protects against low-speed pre-ignition.

In contrast, Quaker State engine oil falls into the ILSAC GF-6 specification, the current ILSAC standard of the (API) American Petroleum Institute. ILSAC GF-6A launched this oil in May 2020 to help prevent low-speed pre-ignition (LSPI), wear protection, enhanced high temperature, and more.

Increased Fuel Efficiency

Accordingly, Pennzoil oil maintains and cleans the engine, critical to enhancing fuel efficiency. Fuel economy can be boosted if the engine is clean and sludge-free. Additionally, Quaker oil contains fuel-saving components to reduce friction and maximize fuel efficiency.

Reduce Sludge Formation

When exposed to oxygen, the oil interacts with engine debris and other contaminants to form sludge, a viscous liquid. This sludge blocks the pipes’ oil flow, reducing the engine’s performance. To prevent sludge formation, it is made with special dispersants and detergents. Generally, because of the higher detergent concentration in engine cleaning, Pennzoil is superior to its competitors.


Gasoline is blended with Quaker State Motor Oil Fuel Economy to make it more synthetic and environmentally friendly. Hence, it significantly decreases engine wear and boosts engine durability.

In fact, Pennzoil helps reduce power loss by reducing automobile engine wear. This increases the durability of the engine compared to its previous design. As a result, the machine has a long service life.

Protection Against Early Oil Burn

Pre-ignition is one of the core determining variables of fuel efficiency. The amount of light particles in an oil affects how well it burns. Having fewer of these particles in an oil can decrease the evaporation rate, allowing it to acquire its entry at higher temperatures. In this way, it can provide fantastic safety against premature burnout. And Quaker State contains lighter particles that have lower temperature evaporates more quickly.


Pennzoil fully synthetic has viscosities of SAE 0W16, 0W20, 5W20, 5W30, and 10W30. These viscosities may vary with temperature and may be thicker or thinner. Indeed, this viscosity thickness can prevent friction between engine moving parts and makes the machine efficient. In contrast, Quaker State has SAE 0w20, 5w30, 5w20, and 10w30 viscosities that can be used under all driving conditions. These viscosities can warm and survive any extreme winter season.

Oil Change Frequency

After 10,000 to 12,000 miles, you must change your Pennzoil Full Synthetic oil. Unfortunately, your engine will drop if you don’t change the oil on time. If you use Quaker State, you should change your oil to 12,000 to 15,000.


Pennzoil Full Synthetic Five Quarts oil is $22.93, and Quaker State’s oil is $19.97 for five quarts.
