FUEL ECONOMY AND MAINTENANCE

A vehicle that is not properly tuned and maintained cannot be expected to perform at its maximum efficiency and can have an adverse effect on fuel economy. The following recommendations will ensure that the vehicle is performing at its maximum efficiency:

• Use the recommended motor oil grade. Using the manufacturer's recommended grade of Mopar® motor oil can improve fuel mileage by 1-2%. Mopar® motor oil labeled "Energy Conserving" contains friction-reducing additives.
• Check and replace air filters. Replacing a clogged air filter with a new Mopar® air filter can improve fuel mileage by as much as 10%.
• Keep the engine tuned. Repairing a vehicle that is noticeably out of tune can improve fuel mileage by an average of 4%. Maintaining a vehicle and repairing problems, such as a faulty oxygen sensor, can improve mileage by as much as 40%.
• Keep tires properly inflated. Underinflated tires can lower fuel mileage by 0.4% for every 1 psi drop in pressure of all four tires.
