Forgive my ignorance here, but I can't seem to find a good maintenance schedule for the Mach 1. The best I can find online is a list of mileage milestones and what should be done/inspected at that time, but I WFH and put few miles on my car, so it would be great to see a breakdown of when Ford recommends getting each wearable item or changeable fuel replaced (after X miles or N years). Can anyone point me to anything like that?

Thanks in advance!

I've always used 1 year = 10K miles for low mileage vehicle maintenance. Some parts of the manual calls out similar schedule e.g., 60K miles or 6 years. So, if you only have 5K miles but its 6 years old perform maintenance for 60K miles or 6 years.

Incidentally the thing that motivated me to post this thread is that I've had my car for three years and haven't changed brake fluid, which I'm looking to do. Out of curiosity, I checked Ford's official maintenance schedule, and, as far as I can tell, there is ZERO mention of recommended brake fluid change intervals... Then I realized there doesn't seem to be any mention of other fluids like coolant change intervals either.

Is there a separate place for fluids or something? Or are they just suggesting that everything should be on an as-needed basis, and they don't want to suggest anything since people might be running different brands?

Worth reading the Mustang Owner's Manual. In the pdf version, there's Scheduled Maintenance section from page 441. Brake fluid is to be changed every three years, it's high boiling point fluid so it suffices rather than the usual 2 year interval.

I'd definitely change the automatic transmission fluid in the typical most recommended 30-40k miles interval.

Mine is coming up on 3 years, definitely got the brake fluid on my radar this spring. Already bought the fluid and have the Motive power bleeder..

And this is the fluid I used in my 22 GT and plan on using in my Mach 1 as well...

note #4, "requires special equipment available at your authorized dealer"

What equipment are they referring to? I assume any competent independent service shop will have what is needed, not just Ford?

I could be wrong but I believe it's something to do with the ABS module needing a computer to go into bleed mode
I think this only applies if fluid level gets low enough to introduce air into the module though

Curious to know the official answer myself

I believe that references either a pressure or vacuum bleeder for solo bleeding Of course you could always do it with a friend pumping the brakes, old school style.

I believe that as well (the first sentence). The ABS system "reflooding" will only come to play if you completely flush the system. But the regular brake fluid change does not need that.

I am not sure that doing it "old school style" is a right way. There seems to be some intricacies about the fluid change, like the right wheel order, pumping with ebrake, etc. that implies the system is a bit sensitive about how it is supposed to be done. Besides I had two brake fluid changes done in a shop and they screwed up each one, finally had to do it myself.

So I would suggest, before doing it old school style, give yourself an advantage by reading the correct procedure.

#4, helps flush fluid in the ABS system, really not needed IMO. I n theory maybe but on a flush you only get most of the fluid anyway. Don t overthink it. I ve done it old school ways with the help of a bleeder. I ve use both the push and suction types. Furthest wheel then worked my way to the nearest . Never had an issue. Until the hose burst on my power bleeder once, LOL. That s another story. Me personally , and I don t track my cars, I d stick with the OEM Ford performance fluid. You can go up to dot 5 or whatever fancy stuff is out there but those fluid collect moisture even more than most DOT 3-4 fluids do (just so you know).
Porsche also had a "need special equipment" on the brake fluid but I think that also pushed some fluid out of the clutch slave and ABS too, again it s not much to make a difference IMO. Even if your fluid is only 3 years old, you ll notice a harder pedal right away.
EDIT/. there should be an inner and outer bleed nipple on most performance calipers.

If I remember correctly I used just under 4 of these, emptying and refilling most of container and then taking a small bleeder catch cup from each caliper. Removed a little more in the rears and less in fronts to make up for distance.
