2008 FORD F150 engine oil

•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
authorized dealer if the window sticker is not supplied with your vehicle.

1Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the requirements of Ford
specification WSS-M2C930-A and the API Certification mark.2Add the coolant type originally equipped in your vehicle.3Service refill capacity is determined by filling the axle to 1/4-9/16 inch (6-14 mm) below the bottom of the filler hole with
the vehicle on a level surface.
Add 4 oz. (118 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford specification EST-M2C118-A, for complete
fill of 8.8 inch and 9.75 inch Traction-Lok axles.4Service refill capacity is determined by filling the axle to the bottom of the filler hole with the vehicle on a level surface.
For 10.25 inch Traction-Lok axles, use 6.5 pints (3.1L) of Motorcraft SAE 75W-140 Synthetic Rear Axle Lubricant and 8 oz.
(236 ml) of Additive Friction Modifier XL–3 or equivalent meeting Ford Specification EST-M2C118-A.5Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated for life. These lubricants
do not need to be checked or changed 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.6Service refill capacity is determined by filling the transfer case to the bottom of the filler hole with the vehicle on a level
surface.7Approximate dry fill capacity including transmission fluid cooling system, actual refill capacities will vary based on vehicle
application and transmission fluid cooling system (i.e. coolers size, cooling lines, auxiliary cooler capacities). The amount of
transmission fluid and fluid level should be set by the indication on the dipstick’s normal operating range.8Automatic transmissions that require MERCONV should only use MERCONV fluid or fluid that is specified dual usage
MERCON/MERCONV. Refer toscheduled maintenance informationto determine the correct service interval. Use of
any fluid other than the recommended fluid may cause transmission damage.
