Today's vehicles are very different from those manufactured just 10 years ago. The drive toward fuel economy and emission control has made fuel injection commonplace, along with four valves per cylinder. New catalysts have improved emission control even more. Today's diesel engines are much more powerful than their predecessors. And the minivans, light trucks, and sport utility vehicles that are so popular today often operate in areas and with loads that would have been unheard of for the old family car.

Likewise, the Pennzoil motor oil that protects your engine is very different today.

1. Pennzoil consistently leads the way in meeting important new motor oil performance requirements. Pennzoil was first to market products meeting the new automakers' performance standards, ILSAC GF-1 just as we were first with ILSAC GF-2.*

2. Pennzoil provided these GF-2 performance improvements a full five years before they were required for the industry as a whole.
   • Extra protection against thermal breakdown. Fuel injection and multiple valves per cylinder means more efficient use of fuel and hotter overall engine temperatures. Modern engine oils must protect your engine under these harsh conditions.

   • Improved engine oil volatility. As engines run hotter, it becomes more important to ensure that critical lubricating oil is not lost through evaporation.

   • Catalytic converter protection. More stringent air quality standards require better catalyst protection.

3. Pennzoil is not only committed to being first to meet ILSAC standards, we will, by virtue of our leadership position, help develop critical performance improvements in future ILSAC standards.

4. Pennzoil is the only major marketer of motor oil to produce base stocks by the severe hydrotreating (HT) and wax isomerization process, the most revolutionary base oil production process to be developed this century. At an investment of 250 million dollars, this is a significant measure of Pennzoil's commitment to product quality.

Today's technically advanced oils offer other benefits as well: Additives form protective coatings that stay in place, even when the oil is squeezed out by tight engine clearances. And better refining techniques help new oils resist evaporation at high temperatures.

At Pennzoil, we're proud to lead the industry in developing technologically advanced motor oils that exceed the highest standards for U.S. and Japanese cars.

But the real proof is in the field, and we're proud of the many motorists who have taken the time to contact us regarding the hundreds of thousands of miles they've obtained from their engines using Pennzoil.

We're also committed to giving today's drivers the information they need to operate their vehicles more efficiently. So read on-and learn how to get the most from your motor oil.

*The International Lubricant Standardization and Approval Committee (ILSAC) is a consortium of domestic and Japanese auto manufacturers that jointly develops and approves oil performance standards, referred to as gasoline fueled (GF) standards for warranty service. The most recent standard is called ILSAC GF-2 which replaces ILSAC GF-1.
