FAQ:

Why is a motor oil's ability to clean important?

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^® motor oil doesn't just help prevent sludge, it cleans up sludge in the first oil change. And when your engine's running clean, you feel it.

Why is the right motor oil brand so important?

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.

How does oil protect my 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 quietly and 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 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.

Myth: Once you switch to synthetic oil you can never switch back.

This is one of the most persistent myths about synthetic oil – and completely untrue. You can switch back and forth at any time. It is advisable that you use the same oil for top-ups if needed, thereby giving you the best protection from the oil that you have chosen.

Myth: You shouldn’t use synthetic oil in an older vehicle.

The myth is rooted in the idea that synthetic oil is “slipperier,” lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Synthetic oils will enhance the engine protection in older vehicles just as they do for new engines.

Myth: You should break in your engine with conventional oil before you start using synthetic.

Again, there’s no manufacturer we’re aware of that makes this recommendation. Mercedes, Porsche, Corvette, some Cadillac, Volkswagen, Hyundai and several other manufacturers’ cars come from the factory with synthetic oil.
