2003 FORD F250 engine oil

1Your vehicle’s rear axle(s) may be filled with a synthetic lubricant that
may require a lubricant change. Refer to the scheduled maintenance
guide. Axle lubricant quantities should not need to be checked unless a
leak is suspected, service is required or the axle assembly has been
submerged in water. The axle lubricant should be changed any time the
rear axle has been submerged in water.
2Add 236 ml (8 oz.) of Additive Friction Modifier XL-3or equivalent
meeting Ford Specification EST-M2C118-A for complete refill of
Traction-Lok axles.
3Add the coolant type originally equipped in your vehicle.
4Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the end of the dipstick. Check the
container to verify the fluid being added is of the correct type. Refer to
your scheduled maintenance guide to determine the correct service
interval.
Some transmission fluids may be labeled as dual usage, such as
MERCONand MERCONV. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCONtype
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONV type fluid.
MERCON, MERCONV and MERCONSP are not
interchangeable. DO NOT mix MERCON, MERCONV and
MERCONSP. Use of dual usage fluids in an automatic
transmission application requiring MERCONSP may cause
transmission damage. Use of a transmission fluid other than the
recommended fluid may cause transmission damage.
5Service refill capacity is determined by filling the transmission to the
bottom of the filler hole with the vehicle on a level surface. The 6–speed
manual transmission is equipped with an in-tank cooler. Verify the fluid
level after operating vehicle to assure correct fluid level.
6Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick’s normal operating range.
7Use of synthetic or synthetic blend motor oil is not mandatory. Engine
oil need only meet the requirements of Ford specification
WSS-M2C153–H and the API Certification mark.
