Pennzoil Ultra™ keeps pistons up to 25% cleaner than Mobil 1.*
In a recent head-to-head test*, no leading synthetic motor oil—not even Mobil 1—kept pistons as clean as Pennzoil Ultra™. In fact, full synthetic Pennzoil Ultra™ motor oil beat Mobil 1 hands down. So if you are thinking about trading up to a full synthetic motor oil, choose the one that keeps pistons cleaner than any other leading synthetic—Pennzoil Ultra™.**
*Based on ASTM Sequence IIIG piston deposit test using SAE 5W-30. Pistons from standard V6 engine in Sequence IIIG test. Does not apply to Pennzoil Ultra™ Euro motor oil.
**Pennzoil Ultra™ keeps pistons up to 25% cleaner than Mobil 1, up to 35% cleaner than Valvoline Synpower and up to 40% cleaner than Castrol Edge with Synthetic.
NOTHING KEEPS YOUR ENGINE CLOSER TO FACTORY CLEAN.1
The Goal: Design an oil that far exceeds the toughest standards for engine cleanliness—engineered to keep a car’s engine in pristine condition, as it was the day it left the factory
It took one of those stake-in-the-ground moments for us to realize, with engine tolerances becoming so uncompromising and the role of the motor oil so important, we should 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 TechnologyTM . An oil so remarkable that PENNZOIL ULTRA™ is the only motor oil in North America recommended by Ferrari.2 And then we said, why not create an entire family of motor oils dedicated to that same philosophy? It’s one more reason more people trust Pennzoil® than any other oil.3
Unsurpassed Wear Protection:
While all motor oils are designed to offer wear protection, wear protection is just one part of protecting an engine. And one that new Pennzoil Ultra™ does extremely well. It’s a fact that no leading full synthetic motor oil provides better wear protection than Pennzoil Ultra™.4
Unsurpassed Performance Overall:
Far exceeds the most stringent car manufacturer requirements for cleansing and protection.5

Tested Clean Synthetic Oil
Both of these front engine covers were subjected to the same industry test designed to simulate moderate temperature taxicab service, or the typical driving cycles of an urban and suburban delivery service. The test evaluates the oil’s ability to prevent sludge and varnish formation.
The engine cover on the left reflects a passing grade. The engine cover on the right shows the same test conducted with Pennzoil Ultra™. Amazing, isn’t it?
Pennzoil Ultra™ full synthetic oil prevents sludge and damaging deposits from forming by seeking out, dissolving and neutralizing contaminants safely into the oil and cleans up sludge by gently lifting deposits off engine surfaces and dissolving them into the oil.
