Why clean matters.

Engines work best when they’re clean. The problem is, they don’t stay clean for long. Every time you turn your engine on, it continuously generates acids, combustion gases, water vapor and fuel by-products that end up in your oil – your engine’s bloodstream. Unchecked, these contaminants may eventually form deposits that can clog oil passages, gum up moving parts and, ultimately, reduce engine responsiveness. Which is why Pennzoil^® doesn’t just help prevent sludge, it cleans up sludge in the first oil change.

From the moment Pennzoil^® motor oil with active cleansing agents enters your engine it starts to clean away and remove sludge that builds up on components when oil goes through its natural process of oxidation and breakdown. Engineers know that if this grime is left in place it can block key oil ducts and passages and cause premature engine damage. At the same time, Pennzoil^® motor oil delivers a long-lasting anti-wear, friction reducing coating that helps maximize protection to all engines, even during critical cold-start and short-trip driving conditions.

Based on severe sludge clean-up tests, Pennzoil^® Conventional motor oil cleans out up to 15% of engine sludge in the first oil change. Pennzoil^® Platinum^TM Full Synthetic motor oil cleans out up to 46% of engine sludge in the first oil change*.

And when your engine’s running clean, you feel it.

In addition to laboratory testing, field trials with taxi fleets in New York and Las Vegas have demonstrated the cleaning power of Pennzoil^® Conventional motor oil and Pennzoil Platinum^® Full Synthetic motor oil in harsh, real-world driving conditions.
