Ford have made maintaining your Mustang Service history pretty easy with their Intelligent Oil-life Monitor. 

The long and short of it is, based on the type of driving that you are using your Mustang for, the cars on-board computer systems determine when you need to have the car serviced. It lets you know services are due with a simple display message that literally tells you that the oil needs changing. Which is handy. 

When to expect the message to prompt you to change your oil 
Interval  Vehicle use and example 
7000-10000 mi   (12,000–16,000 km)  Normal 
Normal commuting with motorway driving.  No, or moderate, load or towing.  Flat to moderately hilly roads.  No extended idling. 
5000–7000 mi (8,000–11,999 km)  Severe 
Moderate to heavy load or towing.  Mountainous or off-road conditions.  Extended idling.  Extended hot or cold operation.  High engine speeds and loads, engine braking and hard cornering. 
3000–5000 mi (4,800–7,999 km)  Extreme 
Maximum load or towing.  Extreme hot or cold operation. 

 

NOTE: The oil life monitor is still only a guide. Ford continue to recommend that you carry out an annual service on your Mustang regardless of Mileage. The Oil-Life monitor is to ensure that you do not exceed the engine oil lifespan between your annual services.

 At every oil change interval as indicated by the information display  
 Change engine oil and filter.  
 Rotate tires, inspect tire wear and measure tread depth. 
 Perform a multi-point inspection.
 Inspect the automatic transmission fluid level. 
 Inspect the brake pads, rotors, hoses and parking brake. 
 Inspect the engine cooling system strength and hoses. 
 Inspect the exhaust system and heat shields. 
 Inspect rear axle and U-joints. Lubricate if equipped with grease fittings. 
 Inspect the half-shaft boots. 
 Inspect the steering linkage, ball joints, suspension, tie-rod ends, driveshaft and U-joints. Lubricate any areas with grease fittings. 
 Inspect the wheels and related components for abnormal noise, wear,  looseness or drag. 

 

Fords 'Other maintenance items' Schedule 
Every 20000 mi (32,000 km)  Replace cabin air filter. 
Every 30000 mi (48,000 km)  Replace engine air filter. 
At 100000 mi (160,000 km)  Change engine coolant.  
Every 100000 mi (160,000 km)  Replace spark plugs. 
Inspect accessory drive belt(s).  
Every 150000 mi (240,000 km)  Change automatic transmission fluid and filter. 
Change manual transmission fluid. 
Replace accessory drive belt(s). 
Change rear axle fluid. 

 

Now, all this is good for oil changes and health checks. But!!! 100,000 mile spark plug intervals? 30,000 Mile air filter intervals? 150,000 mile diff oil changes? Holy crap! That might work for a car that spends it's days running up and down the freeway. Or maybe it would be fine to keep a car going. If you are more interested in keeping your car in ship shape and performing its best however, we are going to need to sharpen that up somewhat. I mean do you think Ford have ever seen a 30,000 mile old air filter out of a UK car before? I'd expect to find an entire ecosystem in the airbox!

With that in mind we have put together a MAP service schedule for the Performance and forced induction cars. Hopefully everyone who actually likes their car will opt to run with this service plan because to us guys, proper servicing is vitally important!

MAP NA Service Schedule 
 Every 12,000 miles  Replace or clean the engine intake Air filter
 Every 36,000 miles  Replace Spark plugs
 At 50,000 miles  Replace engine coolant with EVANS waterless coolant
 At 75,000 miles   Replace accessory drive belts

 Replace Gearbox and Differential oil

 Stuff to look out for in-between  Service the throttle body
 Clean and flow test injectors after 80,000 miles
 Windscreen wipers
 Clean and grease caliper sliders and boots to prevent them seizing up - UK roads will do that!

 

For the cars running Forced Induction ... well we don't need to tell you that they are going to need a different level of care.

We will right from the get go be suggesting replacing all of the engine fluids with performance alternatives from world leading manufactures, you will be running different engine oil grade, different spark plug heat range and waterless coolant. The engine oil will need to be replaced much more often and the spark plugs will need changing annually.

Over and above that we would recommend replacing your ignition coils every 50,000 miles and put the car on the dyno for a health check along with every service! Failing to catch a fault before it causes big problems can be helishley expensive, so it's always worth been extra careful when you are doubling the factory power output of your car!
