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.

Sooo.... You’re saying that the throttle isn’t a binary switch?

who knew...

I assuming you're tracking your car? Oil life goes down fast when you are doing hot laps. Same with the rear diff.

Otherwise, that is a really aggressive and arguably wasteful maintenance schedule.

Never would consider taking my car to the track, the only thing aggressive is my maintenance.

Mostly it's how you drive in a giving distance: spirited drive will reduce the lifespan by A LOT. If it was for the "computer" I would have to change the oil every 5.000Km or such (VS the 15.000Km given by the manual). However Ford (in my case) never cared about it, neither they raised any question (I reset it via menu), they say it's just a "suggestion" and won't affect the warranty, so I officially do the full oil change every 15.000Km (or at least that's what i did with my S550). For my current DH I changed it earlier because it was the first oil change, and I did it at 8.000Km (I already had to reset the computer thousands kms before), the oil was clean and in great conditions. Will do the next one at 15.000Km and 30.000Km .. and such along with the normal warranty maintenance.

I am my oil life monitor.

I change it at six months or 5000 miles, whichever comes first and then more often if there are extenuating circumstances (hard running, lots of city driving, etc.). Common sense keeps my engines running a long time, historically. Year old oil is worn out, used much or not. Ford wants to sell cars and is only concerned about the warranty period. Don't forget that.

I changed the oil for the first time in February at 9,482 km. After the oil change, the OLM showed 100% life remaining and the next oil change in 10,000 km (shouldn’t it be set to 15,000 km? ).

Now, two months later, I have 15,503 km on the odometer and the OLM shows 20% life remaining and 1,550 km until the next oil change. No track days, just normal spirited driving.

It seems unreasonable to change the oil this often. So if I reset the OLM myself, will it void the warranty?

With my driving style (as of you rarely track, just spirited drive 90% of the time) my OIL change alert show up at least 3 times during the normal cycle (as said, every 5000Km or so, instead of 15000), that's because the "computer" measure how you drive... so I have to reset it myself every time... it was the same with S550.
And no, it will NOT void the warranty, I've already asked my dealer, it's just a recommendation, for the warranty it only count the maintenance intervals.

Thanks, so I’ll just reset it and go for the next oil change at around 23,000 km. For context, the way I drive — I’ve never seen the oil temperature go above 104 °C (219 °F).

 

[npole]

For a matter of caution, time to time, check your oil level (dipstick) to be sure.

 

[mp390]

I check the oil roughly every 1,000 km (I had to top up a little shortly after break‑in, about 250 ml). Now, after 6,000 km, it’s color is still amber, so I believe it’s still fresh.

 

[npole]

Yeah.. mine was pristine at the oil change (and the level never changed).
