Detailed Comparison Between Pennzoil Vs. Valvoline:

Motor oils made from synthetic materials are inherently more durable and less susceptible to thermal breakdown than conventional oils.

Almost 150 years ago, Valvoline was invented, and continues to innovate on it. Valvoline has the perfect engine oil for every vehicle. Discover what’s right for you from Valvoline wide selection.

Most engine oils are made up of crude oil, but Pennzoil synthetic oil contains natural gas as a base. Thanks to Pennzoil’s patented liquid-to-gas process, synthetic oils produced by Pennzoil have a crystal clear appearance and are 99.5% free of impurities.


Pennzoil is the 1st natural gas-based synthetic engine oil. No crude oil. Gas-to-liquid technology creates Pennzoil Synthetic motor oil by converting the gas into crude oil.

Formulated specifically for recent model SUVs, small vans, light trucks, & cars with more than 75,000 miles.

Pennzoil’s high mileage condition seals minimize leaks in older engines & oil consumption. In addition to its excellent performance at extreme temperatures, Pennzoil motor oil also has a lower oil burn-off rate compared to conventional oils.

Valvoline synthetic engine oils offer excellent protection against engine wear & corrosion for all types of vehicles. The Valvoline Durablend Motor Oil is its best-selling product, designed to protect against wear, sludge, & oil breakdown. The high mileage helps improve performance by preventing engine wear resulting from extreme heat & friction.

Valvoline engine oil wins the game in this category. Besides its synthetic products, Valvoline offers older cars and trucks and a few other synthetic products. Ensure you’re using the correct motor oil, because incorrect motor oil can cause more problems than they solve.


Pennzoil oil is famous for its superior quality and high performance. Pennzoil engine oils are specially formulated to meet the high-stress, high-temperature needs of today’s engines.

One of Pennzoil’s flagship products, ultra-high mileage Pennzoil motor oil, was designed especially for cars with high mileage offers. If you drive an older car, and if you travel a lot each year, you should use Pennzoil.

Valvoline synpower provides total protection from extreme temperatures and weather. That’s because it’s designed to perform in hot or cold conditions. It’s so capable of balancing everything. During high temperatures, however, the oil might leak. Moreover, the oil cannot evaporate as it heats up. Therefore, it has both pros & cons.

Here, Valvoline engine oil is the clear winner. If you’re looking for total fuel economy and quality at an affordable price, then Valvoline is your best bet.

Oil Changes Frequently

Valvoline oil needs to be changed after a period of 3000 to 4000 miles. In comparison with its rivals, this engine oil has a lower TBN (Total Base Number), meaning it should be changed more frequently.

In general, Pennzoil oil should be changed between 5,000 to 7,500 miles. Because of this, Pennzoil oil is more efficient and has a longer lifespan. Pennzoil motor oil is produced when oxygen reacts with hydrocarbons in oil, thus requiring fewer oil changes and enhancing fuel economy.

Pennzoil oil wins in this category without a doubt. Pennzoil oil has a higher TBN value than its rival. Thus, its high base content (KOH) neutralizes the acid.

Pros And Cons Of Pennzoil:


  • Regardless of the climate, performance is guaranteed
  • Lubricates and prevents wear on the engine
  • The engine’s efficiency is improved
  • Oil flow is improved for quicker cold starting
  • This extends the lifespan of the pistons
  • Oil can be recycled and re-used


  • Caps should be handled with care
  • This oil may not be suitable for all vehicles

Pros And Cons Of Valvoline


  • Prevents the buildup of sludge & lacquer
  • Capable of working during cold and hot weather
  • Can be used with turbochargers
  • Compatible with conventional & synthetic lubricants
  • Fuel efficiency has been improved.


  • There will be shorter breaks between shifts
  • The case quality is poor

Pennzoil Vs. Valvoline: The Cost of Oil

The price of oil varies with the type and size of the container. Engine oil costs approximately $4 to $10 per liter. The cost of synthetic oil is higher than that of conventional oil. A 5-quart container of Valvoline advanced fully synthetic SAE, 5W-30 engine oil costs $22.47. Instead, Pennzoil Platinum fully synthetic 5W-30 engine oil costs $22.93.

Alternatively, in the case of Valvoline vs Pennzoil, oil changes should be performed every 3,000 to 5,000 miles to keep the engine running smooth. Typically, a 5-quart container of conventional oil costs $35.41 for Valvoline extra Protection SAE, 10W-40 conventional engine oil, and $18.98 for Pennzoil conventional 10W, -30 engine oil.

Pennzoil Vs. Valvoline: Which One Is Better?

Both oils are similar in their properties. But the question is which one is better between Pennzoil Vs Valvoline? In both cases, engine wear is reduced, although Pennzoil offers higher mileage per gallon (MPG). Therefore, if you run your vehicle a lot on interstates, your costs might be reduced over time.

However, Valvoline protects engines better than Pennzoil against sludge buildup. Therefore, Valvoline might be a better choice for people living in colder climates or driving mainly on highways and high-speed routes.

The decision between these 2 synthetic oils mostly depends on your driving habits and your location. Fortunately, Pennzoil and Valvolineboth offer unique advantages.


How do Pennzoil and Valvoline differ?

Valvoline engine oil offers excellent protection against wear & fits all types of vehicles, SUVs, and trucks. Pennzoil synthetic oils provide excellent performance in gas engines & work with nearly any vehicle, such as turbocharged engines.
Using “enhanced” additives, Valvoline provides better protection against friction, sludge, and wear. The Pennzoil Platinum product lasts longer up to oil changes and performs better under low temperatures than Valvoline.

Is Valvoline car oil the best?

Valvoline leads the way in conventional engine oil. Because of its low price, it is very popular. Due to their higher product range and better quality, competitors like Pennzoil & Mobil 1 raise the stakes in the synthetic oil market. The Maxlife motor oil from Valvoline is considered one of the top motor oils for higher mileage.

Does Pennzoil Synthetic provide the best performance?

Reviews from customers, as well as analysis, confirm the effectiveness of Pennzoil products. Pennzoil engine oils are technology-driven with advanced formulations and composition. These variants make old engines last even longer. Variants of Platinum, such as natural gas, are lower in impurities & have superior performance.

Is it possible to mix Valvoline & Pennzoil?

The clear answer is NO. Regardless of the viscosity difference between the two oils, it is still not advised to mix them.

Sum Up

Pennzoil Vs Valvoline: Which should you choose? Which one provides you with better value? Valvoline and Pennzoil differ primarily in that Valvoline can prevent sludge buildup better than Pennzoil. Thus, if you reside in a cold climate or don’t drive a lot on highways, then the Valvoline brand might be a better choice. However, if a smaller fuel consumption results in lower costs, then Pennzoil might be a better choice.

The bottom line is, that choosing the right oil is important, no matter what your needs are! Check out both oils & determine which one is right for you. Our advice can be helpful, but ultimately it is your decision.
