Maintenance and Specifications Poor wiper quality can be improved by cleaning the wiper blades and the windshield. Refer to Windows and wiper blades in the Cleaning chapter. To prolong the life of the wiper blades, it is highly recommended to scrape off the ice on the windshield before turning on the wipers. The layer of ice has many sharp edges and can damage the micro edge of the wiper rubber element. ENGINE OIL Checking the engine oil Refer to the scheduled maintenance information for the appropriate intervals for checking the engine oil. 1. Make sure the vehicle is on level ground. 2. Turn the engine off and wait 15 minutes for the oil to drain into the oil pan. 3. Set the parking brake and ensure the gearshift is securely latched in P (Park). 4. Open the hood. Protect yourself from engine heat. 5. Locate and carefully remove the engine oil dipstick. • 6.2L/6.8L gasoline engines only; for diesel engine information, refer to the diesel supplement. 6. Wipe the dipstick clean. Insert the dipstick fully, then remove it again. • If the oil level is between the two holes, the oil level is acceptable. DO NOT ADD OIL. • If the oil level is at or below the lower hole, add enough oil to raise the level to within the two holes. 375 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
