General Questions About Motor Oil

How does oil protect my engine?

  1. 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.
  2. 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.
  3. 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.
  4. 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.

Why is motor oil’s ability to clean important?

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.

Why do I need protection for my high mileage vehicle?

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.

Changing my Motor Oil

Why does my automobile use oil and how often should I check the oil level?

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 manufacturers recommend checking the engine oil every time you fill your fuel tank.

When should I change my oil?

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.

How should I dispose of my old oil?

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.

What motor oil should I use?

Why is it important to use synthetic oil that cleans?

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.

Why choose a full synthetic oil?

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*. * Based on GM4718M and Honda HTO-06 tests using SAE 5W/30.

Car Care Maintenance

How do I maintain my tire pressure?

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.
