Pennzoil Platinum® Exceeds New Oil Spec For 2011 GM Vehicles
HOUSTON, July 2010—General Motors is introducing dexos1™, a new global engine oil specification for gasoline and E85-fueled vehicles, in all 2011 model year Chevrolet, Buick, GMC and Cadillac vehicles. Basically, the company requires that every owner of these vehicles use an oil that is dexos1™ approved at every oil change. It also encourages owners of pre-2011 GM vehicles (except diesels) to use a dexos1™-approved oil as well, as the new specification offers several advantages over previously available motor oils, including improved levels of:
• Engine cleanliness
• Corrosion protection
• Sludge control
• Wear protection
• Aeration control
• Fuel economy
GM says these will result in improved engine life and performance.
Therefore, every owner of the GM vehicles mentioned — new and old — should be pleased to learn that new, next-generation Pennzoil Platinum® full synthetic motor oil is fully dexos1™-approved in the popular SAE 5W-30 viscosity grade.
And they should be even more pleased to learn that new, next-generation Pennzoil Platinum® actually exceeds dexos1™ standards, particularly in the area of engine cleansing. Pennzoil Platinum® keeps pistons up to 40% cleaner than the
toughest industry standard*. So try new dexos1™-approved Pennzoil Platinum® and Feel The Clean.
