Pennzoil Platinum^® Now Engineered With Adaptive Molecules

HOUSTON, August 2006 – Pennzoil^® has reengineered Pennzoil Platinum^® full synthetic motor oil, introducing adaptive molecules that are designed to survive the searing heat, intense pressures and shearing forces of today&requo;s precision-made engine parts.

‘The unique adaptive molecules in Pennzoil Platinum^® are engineered to manage the constant mechanical stresses inside an engine,” said Robert Sutherland, Team Leader, Pennzoil^® Passenger Car Engine Lubricants. “They constantly change shape and separate as needed to help preserve the proper viscosity under intense heat, high-shear stress and extreme pressures.”

Pennzoil Platinum^® is not just another full synthetic motor oil — its adaptive molecules have been developed to protect against specific engine stresses:

• Heat: When Pennzoil Platinum^® senses severe heat, the adaptive molecules are designed to split apart to resist searing heat that can lead to viscosity breakdown, while still providing excellent protection. When the intense heat is gone, the molecules reform.
  
  
• Shear: Mechanical shearing in the engine can tear oil molecules apart, causing permanent viscosity loss. The tight clearances found in the valve trains and piston ring assemblies can stress oil molecules to the breaking point. The adaptive molecules in Pennzoil Platinum^® are engineered to split into smaller pieces to slip through high-shear areas like these to minimize permanent viscosity loss.
  
  
• Pressure: Extreme pressures in the engine can breakdown the protective layer of oil between moving parts. Engine parts such as cam lobes and bearings push against each other with enough pressure to crush motor oil that gets caught between them. When Pennzoil Platinum^® is exposed to these extreme pressures, its adaptive molecules cluster together, creating a cushion or barrier to absorb the impact, like microscopic shock absorbers.

In addition to its adaptive molecules, Pennzoil Platinum^® contains a unique additive formulation. This formulation provides superior protection against engine wear and deposit formation compared to conventional and synthetic blend motor oil, helping to reduce piston ring-sticking and metal-on-metal contact in the engine.

“Pennzoil Platinum^® is the most advanced product ever developed by Pennzoil, and our new formulation with adaptive molecules demonstrates our commitment to expanding the market for full synthetic motor oil,” said Jeffrey Lack, Director of Marketing, Pennzoil. “Pennzoil is always looking for ways to improve our products, and we have created a full synthetic motor oil that will provide our consumers our ultimate level of protection for their engines.”

Pennzoil Platinum^® with adaptive molecules is available at installer and retail locations in a variety of viscosity grades: 5W-20, 5W-30, 5W-30 Euro and 10W-30.
