Crown Victoria Severe Duty Example: When the odometer has accumulated 3,000 miles (4,828 km) and the idle meter shows 61 hours, a 5,000 mile (8047 km) oil change interval will have been reached: 3,000 road miles + (61 idle hours x 33 miles/idle hour) = 5,013 miles. In metric units this calculation would be 4,828 kilometers + (61 idle hours x 53 km/idle hour) = 8,061 km. REAR AXLE Axle break-in - Police and middle eastern countries only Rear axles in vehicles destined for use by police or in middle eastern countries are equipped with a synthetic lubricant. Do not drive over 100 mph (160 km/h) for the first 1,000 miles (1,600 km) to allow axle components to wear in. Additionally, only synthetic lubricant as specified below should be used when maintenance is performed on the rear axle. Lubricant specifications Item Ford part name Ford part number XY-75W140-QL Ford specification WSL-M2C192-A Rear axle Motorcraft SAE lubricant 75W-140 High Performance Synthetic Rear Axle Lubricant ELECTRICAL Battery - police The Motorcraft௡ maintenance-free battery normally does not require additional water during its life. However, for severe service usage or in high temperature climates, the electrolyte level should be checked at least every five months or 5,000 miles (8,000 km). If the electrolyte level is below the level indicator in any cell, add enough pure water to bring the level up to the indicator. Never add electrolyte (battery acid) to the battery as this could shorten battery life. Battery - long term storage Make sure that the battery is fully charged before putting the vehicle in storage. Disconnect the negative cable if it will be stored for an extended period of time. If the battery is discharged, allow it to warm to a moderate temperature, such as 60°F (16°C), and use a battery charger rather than the vehicles charging system to bring the battery back to full charge.
