Check tyre inflation. Under-inflated tyres can result in a loss of fuel efficiency. This is the least expensive form of preventive and safety maintenance. Tyres should be checked once a month.
Keep your engine tuned. A fouled spark plug dirty air filter/restricted fuel injector can reduce fuel efficiency by as much as 30 percent.
Have the chassis lubricated frequently. This step extends the life of the moving components of the vehicle’s suspension system.
Check battery cables and posts for corrosion and clean them as needed. The battery fluid also should be checked and filled if it is low, unless it is a maintenance-free battery.
Have the lighting system checked frequently, including headlights, turn signals, and brake and taillights.
Check windshield washer blades for cracks, tears and windshield contact. Replace them at least once a year, or sooner if streaking begins.
