ExxonMobil Launches First Synthetic Blend Motor Oils for High-Mileage Engines

New Mobil Drive Clean Plus is Designed to Clean and Protect Engines Better than Conventional Oils

FAIRFAX, Virginia (April 1, 2003) -- Owners of both higher-mileage and newer vehicles can drive with renewed confidence thanks to a new line of ExxonMobil synthetic-blend motor oils, formulated to help clean and restore performance of high-mileage engines and help prevent engine sludge build-up in new vehicles.

Mobil Drive Clean Plus 5W-30 Newer Vehicle Formula and Mobil Drive Clean Plus 10W-30 and 10W-40 High Mileage Formulas contain 23 percent more performance additives than Mobil conventional oils. In addition, the Mobil Drive Clean Plus high-mileage formulas are the first synthetic-blend motor oils designed to help clean and protect worn parts, increase performance, and reduce oil consumption in high-mileage vehicle engines.

"ExxonMobil's new Mobil Drive Clean Plus line of motor oils represents a significant milestone for car owners who want to slow the ravages of time and miles on their older cars' engines or keep their newer cars' engines performing like new longer," said Tom Olszewski, automotive lubricants advisor, ExxonMobil Lubricants & Specialties. "By using Mobil Drive Clean Plus motor oil, car owners will be taking a positive step toward improving the cleanliness and performance of their vehicles' engines."

Mobil Drive Clean Plus isn't just for high-mileage vehicles. With its 5W-30 viscosity grade, the newer vehicle formula is the right viscosity for a majority of newer car models and can help maintain the cleanliness of newer car engines.

Drive Clean Plus synthetic-blend motor oils and their performance enhancing additives offer drivers a common-sense approach for cleaning up their car engines and achieving long-term performance results," said Pat Goss, car care expert, columnist and host of Goss's Garage on PBS television.

"With Mobil Drive Clean Plus, car owners don't run the risk of clogging oil passages and causing engine damage like they could with an aggressive, more expensive one-time oil flush," says Goss.

Mobil Drive Clean Plus synthetic-blend motor oils meet the latest industry standards for gas and light-duty diesel engines as set by the American Petroleum Institute (API). The newer car formula exceeds the standards of the International Standardization and Approval Committee (ILSAC), which requires demanding fuel-economy performance, and is rated an energy-conserving oil.

Mobil Drive Clean Plus synthetic-blend motor oil formulations offer the following help:

High Mileage Formula: Clean Up and Performance Restoration

o Cleans away deposits and sludge build-up - In head to head field, engine and lab deposit tests against Mobil Drive Clean conventional oil, the Mobil Drive Clean Plus High-Mileage formulation decreased the level of deposits in both the lab bench and engine test. In severe duty field-testing, it reduced the precursors that form deposits.
o Conditions seals to prevent leaks - In a laboratory seals test, the Drive Clean Plus High-Mileage Formula helped control seal shrinkage, which occurs over time and can cause seal leakage.
o Restores engine performance - A combination of three separate studies demonstrated that the Drive Clean Plus High Mileage Formula helped to: 1) Control deposits and improve piston ring sealing, 2) Provide both improved high and low temperature deposit control, which leads to better oil flow, improved engine cooling, and improved operation of engine rings, valves, and other critical engine parts, thereby restoring engine performance.
o Reduces oil consumption - During a chassis dynamometer roll test of an engine with high amounts of sludge, high oil consumption was measured. Using Mobil Drive Clean Plus High-Mileage, oil consumption was reduced from approximately three quarts of oil every 1,000 miles at the start of the test, to one quart every 1,000 miles, after running the engine 22,500 test miles with normal oil changes of Drive Clean Plus High Mileage Formula.
o Protects worn engine parts - The same chassis dynamometer roll test also showed that low levels of wear were maintained during the test as indicated by used oil analysis. This demonstrates that the Mobil Drive Clean Plus High Mileage Formula continued to provide excellent wear protection during the test.

Newer Vehicle Formula: Cleans, Maintains and Protects

o Keeps engines cleaner longer - In a taxicab field trial evaluating the Mobil Drive Clean Plus Newer Vehicle Formula against six conventional oils, the Drive Clean Plus formula showed less tendency to form deposits in the engine than any of the conventional oils.
o Prevents deposit formation to keep engine cleaner longer - During two separate studies, the Mobil Drive Clean Plus Newer Vehicle Formula demonstrated -- against the baseline GF-3 oil, less deposit precursors over an extended oil drain interval (10,000 miles), resulting in longer lasting deposit control and less piston deposit formation, well below the maximum allowable limit.
o Provides longer lasting protection - When a lubricant is exposed to high temperatures and severe driving conditions it thickens. In a thicker, oxidized state the oil can not lubricate or flow as effectively to protect your engine. In the industry standard test that measures oxidation and high temperature stability, Mobil Drive Clean Plus Newer Vehicle Formula provided exceptional protection against oil thickening.

The new Mobil Drive Clean Plus family of synthetic blend oils will be available beginning April 15 through a wide range of retail and mass merchandisers, auto parts stores, Mobil service stations and some Exxon service stations. Many quick lube shops and independent auto repair centers also will carry Mobil Drive Clean Plus oils and can install it for consumers.
