Switching to synthetic oil can boost performance

Motor oil is one of the most important fluids in your vehicle, and changing it regularly is an essential part of vehicle maintenance.

Clean motor oil picks up dirt, deposits, metal particles and various other impurities from throughout your vehicle's engine.

Regular oil changes (every three months or 3,000 to 5,000 miles) are necessary to ensure the proper performance of a car's engine.

An oil change, which involves installing a new oil filter, draining old engine oil and replacing it with fresh, clean oil, offers a multitude of benefits including lower emissions, better fuel mileage and better engine performance.

Next time your vehicle is up for an oil change, consider switching to a fully synthetic motor oil which will provide a variety of benefits to help keep your engine running at optimal performance.

In general, using synthetics offers the following added advantages over conventional motor oil:

• Increased engine life
• Increased durability
• Longer oil change intervals
• Remains functional under extreme cold or hot driving conditions

Synthetics work well in today's modern engines that have tighter tolerances and smaller oil passages that need a functional lubricant.

In general, synthetic motor oils are more durable. By using them, motorists can extend oil change intervals and engine longevity.

To meet the demanding requirements of today's specifications, companies like the official motor oil of NASCAR -- Mobil 1 -- use high-performance fluids along with a proprietary system of additives. Each viscosity grade uses a unique combination of synthetic fluids and selected additives to tailor the viscosity grade to its specific application.

Touting the value of fully synthetic motor oil in today's car care, Mobil 1 and O'Reilly Auto Parts are giving four NASCAR fans the trip of a lifetime to join the year's top drivers in Las Vegas for 2010 Champion's Week. Enter now through Sept. 30 by visiting www.mobil1.com/championsweek.
