Just a few notes which might help someone with DIY oil changes
on the Mondeo 2007-2014 diesel.

The oil filter is upside-down, which can lead to spills.
It's also cramped, unlike my old EF when I used to sit in the engine bay.

Don't remove the filter housing too soon after
the engine has been running. Result: oil in hard to reach places.
Wait half an hour at least before unscrewing the filter housing,
which allows the oil to drain out of the filter.

Another problem is actually getting the housing off. I use a 27mm ring spanner
(el cheapo) with one end cut off to leave 250mm total. This works fine for me, but
there is a Ford tool like a 27mm ring spanner bent into a C shape with a half-inch drive at the other end.

Otherwise it's going to be very difficult.

Because the filter mounting points up, I blow the area out with compressed air before
removing the housing, in case sand etc falls in.

Lubricate the rubber catches for the engine cover with dilute soap or thin smear
of castor oil/rubber lubricant if it's hard to release, else the cover could break.
Mine was broken when I bought it.

Unclip the filler neck and move it aside to get access to the filter.

Drain plug is 21mm. Undertray 10mm.
I fill with 5.5 litres Nulon full synthetic diesel oil. That brings it to the mid-point
on the dipstick scale, where I like to keep it. I check the level only in the morning
after it's been standing all night, otherwise it tends to be smeared out.

While I'm under the car I relax and shine a very bright torch into all the nooks
and crannies, wondering what I'm looking at. :-). Level ground and safety stands of course.
