Frequently Asked Questions

By cleaning your engine. Pennzoil motor oils don’t just help prevent sludge, they’re designed to clear away dirt, debris and deposits from engine components and prevent blockage of oil passage ways. The oil locks up the dirt, rendering it harmless until it’s removed at the next oil change.  

By reducing friction and minimizing wear. Pennzoil motor oil forms a protective film over your engine components, and has special additives between engine surfaces preventing contact and reducing drag. This helps your engine operate as quietly and effectively as the engineers intended.

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

By preventing corrosion and rust. Pennzoil motor oils protect your hardworking engine components from corrosion over 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.

Keeping engine components clean is essential, as it keeps them in good condition. If your engine components and passages are dirty, your oil may not be lubricating and protecting as it should. Deposits also trap heat inside your engine like an insulating blanket. That is why Pennzoil just doesn’t prevent sludge, it cleans up sludge in the first oil change. When your engine is running clean, you feel it.

There no denying that higher mileage engines need special care. They have fought the good fight in traffic, at highway speeds and in extreme conditions, and they have 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.

Vehicle engines require motor oil to lubricate and protect internal parts from wear. When the piston moves down its cylinder wall, a thin film of oil is left on the cylinder wall. Part of this film is consumed in the combustion process. As a result, varying rates of oil consumption is considered normal in all engines. Leaks from gaskets and seals also contribute to loss of engine oil.

NOTE: Most vehicle manufactures recommend checking the engine oil every time you fill your fuel tank.

You should change your oil and filter, at or before the oil change intervals provided by your vehicles manufacturer. These intervals are based on mileage or time. By doing this, you can keep your engine in good condition and providing the best protection for all your components.

Used oil can pollute the environment and should never be poured down the drain. The Pennzoil “Clean Change Campaign” helps Do-it-yourselfers protect the environment. At Pennzoil 10 Min. Oil Change we will recycle your used oil, just bring it in up to 5 gallons per visit.

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 new, proprietary ultra-class full synthetic motor oil that does just that. Our new standards of new synthetic oils by Pennzoil, that nothing keeps your engine close the factory clean, than new Pennzoil Ultra.

Pennzoil Platinum is advanced 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 the engine sludge on the first oil change. And continues to clean on the 2nd oil change**. The ability to clean up your engine helps maximize engine protection and responsiveness.

* Superior versus our conventional and synthetic blend oils.

Pennzoil High Mileage Vehicle is a conventional motor oil that has been enhanced with a unique combination of conditioning agents and additives to help stop leaks from seals and reduce the oil consumption that is typical of older, worn engines. It is 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 for a long time, month after month, year after year.

Pennzoil Conventional Motor Oil is a traditional mineral oil base, fortified with Active Cleaning 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 40% of sludge in the first oil change and keeps on cleaning into the second oil change*.

Simply put, a cleaner engine is better protected and responsive. It’s a fact of life that all engines produce contaminants. Contaminants such as soot, carbon, nitric and sulfuric acids are inevitable by products of the combustion process. All of them end up in the motor oil in varying degrees. So the question isn’t whether you need  oil that cleans, but how well your oil cleans the dirt and deposits that your engine generates.

Part of the job of 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 Pennzoil Platinum does a better job of preventing deposits on engine surfaces than conventional oil and synthetic blends can do. In fact, Pennzoil Platinum exceeds certain cleanliness standards that conventional and synthetic blends oils can’t meet*.

Inflating and maintaining proper tire pressure ensures safer, more comfortable driving and better fuel efficiency. You can improve your gas mileage by keeping your tires inflated to the proper pressure.  Particularly in times of high gas prices; in inclement driving conditions such as heavy rain, snow, or ice; and in vehicles of all sizes, tire pressure can make a major difference in driving, wherever you are.

Given the importance of the task, you might think it is complicated, but checking and maintaining your tire pressure is simple, provided you have a good tire air pressure gauge and source of air.

The proper tire pressure for your vehicle is usually found on a sticker in the driver's side door jamb or the glove box and in your owner's manual. Do not use the maximum pressure printed on the tire's sidewall.

Wiper blades are one of the most neglected components on vehicles today. Many blades are cracked, split, torn, brittle, worn or otherwise in obvious need of replacement.

Ninety percent of all driving decisions are based on a clear unobstructed view of the road, which means good visibility is absolutely essential -- especially during wet weather when vision may be obscured by water, road splash, sleet or snow on the windshield. But good visibility requires wipers that are in good condition. If the wipers are chattering, streaking or otherwise failing to wipe cleanly and consistently, you need new blades -- NOW!

Most experts say wiper blades should be replaced every six to twelve months for optimum performance and driving visibility. That's because wiper blades don't last forever. Natural rubber deteriorates over time. Eventually all blade materials fall victim to environmental factors. Exposure to sunlight and ozone causes the rubber to age, even if the wipers aren't used much.

The cabin filter in your vehicle is responsible for filtering the air before it enters the vehicle’s cabin. The cabin air filter catches pollen, dust, dirt and other impurities from the air, keeping the air purified for the vehicle and its passengers. It’s important to keep the cabin air filter clean so when the heater or air conditioner is running, the air being emitted is quality air. The cabin air filter should be replaced every 15,000 to 30,000 miles or as needed.
