All the time your engine is operating it's generating acids, combustion gases, water vapor and fuel byproducts; these contaminates attack the motor oil throughout your engine. Unchecked, they will eventually form deposits that can clog oil passages, gum up moving parts and ultimately can reduce engine responsiveness.
Having a clean engine can be critical to engine performance – the way it feels when you step on the gas.
That's why Pennzoil® motor oil is formulated with Active Cleansing Agents that not only help prevent engine sludge, but also clean out up to 15% of built-up sludge.*
Pennzoil Platinum® cleans 3X better than the leading conventional oil.*
The Superior Active Cleansing Agents† in Pennzoil Platinum® full synthetic motor oil not only helps prevent engine sludge, but also can clean out up to 46% of built-up sludge in the first oil change.*
In addition, Pennzoil Platinum® is formulated with Adaptive Molecules, which help resist the breakdown caused by heat, shear and pressure in your engine. Less oil breakdown means fewer deposits, helping keep the engine cleaner still.
