Why Is It Important to Use a Motor Oil made with Natural Gas?

All engines generate contaminants such as soot, carbon, and sulfuric and nitric acid. These contaminants are inevitable byproducts of the combustion process, and all of them end up in your motor oil, to varying degrees. So, the question isn’t whether you need an oil that cleans, but how well your motor oil cleans the dirt and deposits your engine generates.

To put it simply, a cleaner engine is better protected, has a higher quality performance, and works more efficiently than a dirty one.

This is why it’s important to use a motor oil like Pennzoil Platinum® Full Synthetic motor oil made with natural gas, that helps keep engines cleaner than any leading synthetic motor oil.

The Proof is in the Pennzoil.

Many people wonder about the benefits that come from using synthetic motor oil made with natural gas, especially since they notice the price tag is slightly higher than conventional motor oil. It all comes down to science and innovation.

Base oil makes up nearly 80% of a motor oil formulation and additives make up the remaining nearly 20%. The chemically engineered molecules in synthetic base oil have more uniform properties while the molecules found in conventional base oil differ in shape and levels of impurity. This shift to a cleaner, higher quality product is becoming the norm in the automotive world with 70% of new cars using synthetic motor oil to help maintain performance.

Pennzoil Synthetic motor oil, takes things to the next level of performance because they use base oil made with natural gas, which is purer than base oil made from crude oil. With the help of this revolutionary gas-to-liquid technology, your vehicle can experience complete engine protection including cleaner pistons1better fuel economy2horsepower protection3, unsurpassed wear protection4, and extreme temperature performance.
