Engines work best when they’re clean. And when your engine’s running clean... you feel it.

EVERY PENNZOIL® MOTOR OIL HAS BEEN FORMULATED TO CLEAN EVEN BETTER.

 

The Technology of Clean

Why is clean so important in today’s engines? Engines are born clean at the factory. In fact, if you were to visit the engine-assembly facilities of state-of-the-art engine builders like Ferrari, you’d find that they more closely resemble semiconductor clean rooms. That’s because the tolerances in today’s engines are tighter than ever, and today’s engine builders know that clean is crucial.

 

Dirt happens

The problem is, even pristine engines don’t stay pristine 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 Ñ 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. Tighter tolerances = less tolerance for dirt and deposits.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

A measurable percentage of these by-products end up in the crankcase oil, potentially contaminating the oil. When dispersed properly in oil, the filter can trap the larger particles. Contaminants too small to be filtered are removed with the engine oil change.

 

 

 

 

 

 

 

 

 

 

 

 

Enter Pennzoil Ultra™

 

 

 

 

 

 

 

 

 

So recently we had one of those stake-in-the-ground moments and said to ourselves, with engine tolerances becoming so uncompromising and the role of the motor oil so important, what if we could create a new kind of motor oil that keeps engines as close as possible to factory clean? And then we went about achieving it. The end result of that exploration is new Pennzoil Ultra™ with Hyper Cleansing Technology™. An oil so remarkable that it is the only motor oil in North America that is recommended by Ferrari. And then we said, why not create an entire family of motor oils dedicated to that same philosophy? That's next-generation Pennzoil®. An entire family of motor oils that clean so well, they turn your engine into a self-cleaning engine.

 

 

 

 

 

 

 

 

 

 

 

 

Why is clean so much more important now than before?
