Maintenance intervals

[robvas]

I bought the Expensive service warranty So when my Dark Horse say's go change oil. I just go to the dealer and they change it with synthetic oil. I only drive it in nice weather so it only has 4,200 kilometer on the car. It is now telling me to go in again for a change. Not sure if it's based on time intervals or Kilometers driven?

Time + driving data

It will tell you to change the oil in 1 year even if you only put 150 miles on the car

Not sure if it's based on time intervals or Kilometers driven?

The OLM watches a variety of variables to determine how quickly to countdown. Time, RPMs, how long driven each drive, temperatures, mileage, etc.

At one end of the spectrum, if you change the oil today, reset the monitor, park it and not drive it, the counter will reach 0% in one year. -1.923% a week. At the other extreme, for those that track often, the counter will tick down much faster.

Attached is an technical explanation, by Ford.

GWM - Gateway Module. A switch, linking the different networks, internal to the car.
HS-CAN - High-Speed Controller Area Network. The Mustang has four, linked by the GWM.
IPC - Instrument Panel Cluster.
PCM - Powertrain Control Module. Monitors and controls the engine, transmission and accessories.

I take what Ford recommends and reduce it 50% sometimes even more. Have an excel spreadsheet for all my maintenance on all my cars.
