2024 FORD F650/750 oil level

Your vehicle can be driven in such a waythat dilutes and increases the level of oilby short trips that do not allow the engineto get to operating temperature, extendedidling, and low speed driving for longperiods of time.
A message appears in the instrumentcluster display when it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi(800 km) of the message appearing. Makesure you reset the Intelligent Oil-LifeMonitor after each oil change. SeeInstrument Cluster (page 64).
If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5,000 mi (8,000 km) fromyour last oil change. Never exceed one yearor 10,000 mi (16,000 km) between oilchange intervals for gas engines.
Never exceed one year or 15,000 mi(24,000 km) between oil change intervalsfor diesel engines.
Your vehicle is very sophisticated and builtwith multiple, complex, performancesystems. Every manufacturer developsthese systems using differentspecifications and performance features.That is why it is important to rely upon yourdealership to properly diagnose and repairyour vehicle.
Ford Motor Company has recommendedmaintenance intervals for various partsand component systems based uponengineering testing. Ford Motor Companyrelies upon this testing to determine themost appropriate mileage for replacementof oils and fluids to protect your vehicle atthe lowest overall cost to you andrecommends against maintenanceschedules that deviate from the scheduledmaintenance information.
We strongly recommend the use of onlygenuine Ford, Motorcraft orFord-authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
This owner's manual and the FordWorkshop Manual list the recommendedadditives and chemicals for your vehicle.We do not recommend using chemicals oradditives not approved by us as part ofyour vehicle’s normal maintenance. Pleaseconsult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is anormal operating characteristic and, byitself, does not necessarily indicate aconcern or that the fluid needs to bechanged. However, a qualified expert, suchas the factory-trained technicians at yourdealership, should inspect discolored fluidsthat also show signs of overheating orforeign material contaminationimmediately.
Make sure to change your vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is aviable way to change fluid for many vehiclesub-systems during scheduledmaintenance. It is critical that systems areflushed only with new fluid that is the sameas that required to fill and operate thesystem or using a Ford-approved flushingchemical.

Rear Axle Maintenance
A rear axle fluid change or level check isnot required unless you suspect a leak orthe assembly has been submerged inwater. During long periods of trailer towingwith outside temperatures above 70°F(21°C), and at wide-open throttle for longperiods above 45 mph (72 km/h), changethe rear axle fluid every 24,000 mi(38,000 km) or three months, whichevercomes first.
California Fuel Filter Replacement
If you register your vehicle in California, theCalifornia Air Resources Board hasdetermined that the failure to perform thismaintenance item does not nullify theemission warranty or limit recall liabilitybefore the completion of your vehicle'suseful life. We, however, urge you to haveall recommended maintenance servicesperformed at the specified intervals andto record all vehicle service.
Hot Climate Oil Change Intervals
The normal oil change interval is 3,000 mi(5,000 km) for gasoline vehicles operatingin the Middle East, North Africa,Sub-Saharan Africa or locations withsimilar climates using American PetroleumInstitute (API) oils Certified for GasolineEngines and displaying the API CertificationMark. If API Certified Oils are not available,then it is acceptable to use API SM or SNoils. If API oils are not available, then theoil change interval is 1,750 mi (3,000 km).
Engine Air Filter Replacement
The life of the engine air filter is dependenton exposure to dusty and dirty conditions.Vehicles operated in these conditionsrequire frequent inspection andreplacement of the engine air filter andcabin air filter.
Diesel Particulate Filter
Over time, a slight amount of ash buildsup in the diesel particulate filter, which isnot removed during the regenerationprocess. The filter may need to be replacedwith a new or remanufactured part atapproximately 250,000 mi (400,000 km).Actual mileage varies depending on engineand vehicle operating conditions.
In this case, the engine control system setsa service light (wrench icon) to inform youto bring your vehicle to the dealer forservice. If there are any issues with theoxidation catalyst or particulate filtersystem, a service light (wrench or engineicon) sets by the engine control system toinform you to bring your vehicle into adealer for service.
