Keeping engine components clean is essential, as it helps keep them in good condition. If your engine components and oil passages are dirty, your oil may not be lubricating and protecting your engine as well as it should. Deposits also trap heat inside your engine like an insulating blanket. Which is why Pennzoil® doesn’t just help prevent sludge, it can clean up sludge in the first oil change. And when your engine’s running clean, you feel it.

Oil is the lifeblood of your engine. By putting Pennzoil® motor oil with Active Cleansing Agents™ in your engine, you can carry on driving with confidence and experience the feeling that comes with a clean engine.

By cleaning your engine — Pennzoil® motor oils don’t just help prevent sludge, they’re designed to clear away sludge, dirt, debris and deposits from engine components and prevent blockages of important oil ways. The oil locks up the dirt, rendering it harmless until it is removed at the next oil change. That’s why with Pennzoil® motor oils, when your engine’s running clean, you feel it. By reducing friction and minimizing wear — Pennzoil® motor oils form a protective film over your engine components and have special additives between moving surfaces, preventing contact and reducing drag. This helps your engine to operate as effectively as the designers intended.

By removing heat — Pennzoil® motor oils carry heat from hot areas, such as around the piston rings where temperatures can top 600°F, helping to protect critical parts from intense heat.

By preventing corrosion and rust — Pennzoil® motor oils protect your hardworking engine components from corrosion during the normal oil-change interval. Our field test data shows that Pennzoil®stands up to extreme conditions and protects your engine from searing desert heat and harsh cold winter driving conditions.

Today’s tighter-tolerance engines require a motor oil that keeps them as close as possible to factory clean. Because the tighter the spaces between critical engine parts, the more crucial it is that the oil keeps those surfaces clean and protected. Pennzoil Ultra™ with Hyper Cleansing Technology™ is a proprietary ultra-class full synthetic motor oil that does just that. Our standard in synthetic motor oils by Pennzoil, because nothing keeps your engine closer to factory clean* than Pennzoil Ultra.™

Pennzoil®Platinum® is an advanced full synthetic motor oil. Formulated with Superior Active Cleansing Agents,* it continuously attacks potential and stubborn deposits to help keep vital engine parts clean. In fact, Pennzoil® Platinum® cleans out up to 46% of engine sludge in the 1st oil change.** And continues to clean in the 2nd oil change.** The ability to clean up your engine helps maximize engine protection and responsiveness.

Simply put, a cleaner engine is better protected and more responsive. It’s a fact of life that all engines generate contaminants. Contaminants such as soot, carbon, and sulfuric and nitric acid are inevitable by-products 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 oil cleans the dirt and deposits your engine generates.

Part of the job of an engine oil is to suspend these contaminants within the oil until your next oil change. It’s a fairly daunting task for engine oil to suspend all the contaminants thrown at it; truth is that full synthetic Pennzoil®Platinum® does a better job of preventing deposits on engine surfaces than conventional oils and synthetic blends can do. In fact, Pennzoil® Platinum® exceeds certain cleanliness standards that conventional oils and synthetic blends just can’t meet.*

Pennzoil® High Mileage Vehicle® is a Pennzoil® conventional motor oil that has been enhanced with a unique combination of special conditioning agents and additives to help stop leaks from seals and reduce the oil consumption that is typical of older, worn engines. It’s an oil that is specifically designed for new or late model vehicles with over 75,000 miles, to help keep the engines running clean and going strong a long time, month after month and year after year.

There’s no denying that higher mileage engines need special care. They’ve fought the good fight in traffic, at highway speeds and in extreme conditions, and they’ve done it for a long time. They’re the road warriors, the engines that consistently get it done. As their internal parts and seals wear, they need added protection to keep them at their best.

Pennzoil® Conventional motor oil is a traditional mineral oil base, fortified with Active Cleansing Agents™ to continuously prevent dirt and contaminants from turning into performance-robbing deposits, helping to keep your engine clean and responsive. In fact, Pennzoil® motor oil cleans out up to 15% of sludge in the first oil change and keeps cleaning all the way to your next oil change.* *Based on a severe sludge clean-up test using SAE 5W-30

Nope. Today’s engine oils are formulated to fully protect the engine. They don’t need extra help.

Used oil can pollute the environment and should never be poured down the drain. The Pennzoil® Clean Change campaign helps DIYers protect the environment. Find your closest Walmart Tire & Lube Express where you can drop off old oil and oil filters to be recycled properly.
