Pennzoil Platinum(R) full synthetic cleans out sludge in first and second oil change

HOUSTON, May 4 /PRNewswire/ -- As recession-weary Americans prepare to escape to the roadways this summer, they can leave some of their worries behind simply by using Pennzoil motor oil. By maintaining their vehicles using Pennzoil conventional or Pennzoil Platinum(R) full synthetic motor oil, motorists can help clean sludge out of their engines in just one oil change. Now, Pennzoil Platinum full synthetic motor oil has demonstrated the ability to continue to clean engines even further in the next oil change.

In 2008, Pennzoil, America's top-selling motor oil, introduced its "Feel the Clean" campaign to communicate that Pennzoil conventional motor oil can clean out up to 15 percent of engine sludge, and Pennzoil Platinum full-synthetic motor oil can clean out up to 46 percent of engine sludge -- all in the first oil change. Pennzoil Platinum motor oil's ability to clean out sludge in the second oil change is an extension of the brand's focus on helping keep engines clean, and a clean engine's connection to the driver.

"Pennzoil's ability to continuously clean an engine highlights our advanced technology," said Troy Chapman, marketing team leader for Pennzoil. "Pennzoil actively cleans up sludge that may already exist in your engine, giving drivers what they really want - a clean-running engine that can maintain responsiveness and invigorate the driving experience."

The active cleansing agents in Pennzoil conventional and superior active cleansing agents* in Pennzoil Platinum full synthetic motor oil not only help prevent sludge formation -- these oils can actually remove sludge from a dirty engine(1). The oils also deliver more sludge protection than minimum specification oils and can assist engines that are prone to sludge formation.

"The importance of a clean-running engine should not be underestimated," said Robert Sutherland, principal scientist, Pennzoil Passenger Car Engine Lubricants. "If sludge build-up becomes excessive, your engine can suffer from a number of problems, including higher engine temperatures, loss of performance and fuel economy, excessive oil consumption and in extreme cases, even engine failure."

Sludge can be caused in newer and older engines by several factors, including low-quality fuel, poor-quality engine oil, poor engine oil maintenance and mechanical issues related to engine design. Taking the engine apart and cleaning it manually to completely remove sludge is difficult and costly.

"Pennzoil motor oil was developed to help avoid these problems. Vehicle owners should use quality fuel and change their oil according to vehicle manufacturers' recommendations using a high-quality Pennzoil motor oil," recommends Sutherland.

When it comes to Pennzoil Platinum motor oil's ability to protect the engine, real-world results tell the story. Grueling testing with a fleet of New York City taxis show that Pennzoil Platinum(R) full-synthetic motor oil cleans and protects engines in harsh driving conditions. After more than 100,000 miles of driving and regular oil changes with Pennzoil Platinum, photos of the taxis' engines show almost completely clean engine parts.

Pennzoil Platinum(R) and Pennzoil(R) Conventional motor oils are available in a variety of viscosity grades. Visit www.pennzoil.com for more information.
