Take Control of Your Fuel Efficiency

Fast Lube Leader Helps Consumers with Fuel Efficiency Tips and $10 Prepaid Gas Cards

HOUSTON - As costs to operate a vehicle continue to rise, drivers want to take more control of improving their fuel efficiency. That's why Jiffy Lube International is putting customers back in the driver's seat with a fuel efficiency review to help get the most out of their gas mileage this summer. Beginning June 18, customers who purchase a Jiffy Lube Signature Service® Oil Change at participating service centers will receive a Fuel Efficiency Review detailing tips that can save them up to fifty-five cents per gallon.* Customers will also receive a ten dollar valued American Express® prepaid fuel card to use towards their next fill-up as part of The Perfect 10 promotion**.

"Finding ways to maximize fuel efficiency is without question a top priority for drivers," said Lisa Carlson, global director of marketing at Jiffy Lube International. "Jiffy Lube can be a part of the solution for our customers. In addition to providing a Fuel Efficiency Review to help drivers improve gas mileage, The Perfect 10 promotion rewards our customers with tangible savings on gas."

Fuel Efficiency Review – Improve Gas Mileage

During each Jiffy Lube Signature Service® Oil Change, a Jiffy Lube technician visually inspects the engine air filter. Replacing a clogged engine air filter can improve gas mileage by as much as thirty-seven cents per gallon.* In addition, Jiffy Lube technicians will replace the vehicle's motor oil with a fresh supply based on the vehicle manufacturer's recommended grade, which can improve gas mileage as much as seven cents per gallon.* The review also includes a check of the vehicle's tire pressure against the vehicle manufacturer's recommendations. Keeping a vehicle's tires inflated to the proper pressure can improve gas mileage up to eleven cents per gallon.*

Free Gas – The Perfect 10

This summer Jiffy Lube is adding more value by offering a ten dollar valued American Express® prepaid fuel card**. Customers who purchase a Jiffy Lube Signature Service® Oil Change will receive a simple form to complete and mail-in along with the invoice to receive their American Express® prepaid fuel card**. The Perfect 10 promotion is a convenient way to help drivers keep a little extra money in their wallets that they can spend enjoying their favorite pastime this summer.

Easy Tips for Ongoing Gas Savings

Jiffy Lube offers these everyday tips that drivers can follow to improve gas mileage even more:

• Use cruise control and overdrive gears to maintain a consistent speed
• Observe the speed limit
• Avoid aggressive driving including speeding and rapid acceleration and braking
• Lighten a vehicle's load by removing non-critical items
• Determine if you're a "severe" driver and adjust your regularly scheduled service intervals accordingly, consult your owner's manual for more details on severe driving habits.
