Default Oil Change for Si6 Engine

I did a first oil change on my gas engine. Here's some info that might help you.
This is for a change using the drain plug.
I removed the under panel/skid plate using a 15mm socket. Two bolts in the back have keyhole slots and can just be loosened. They support the rear of the skid plate without having to hold it up. Especially useful when reinstalling but the skid plate is pretty light anyway (not has heavy as an LR3's).
The oil drain plug takes a 13mm socket.
The standard aftermarket oil filter cap wrench (I think it was 90mm) is too loose. I fixed it by rapping each flute of the wrench with a hammer and it now fits snugly.
The oil filter swap is very easy. Just pull out the old filter from the cap and press the new one in place, be sure to line up the two tabs so it fully inserts into the cap, then swap the large o-ring that comes with the filter.
I only drained 7.0 quarts. Since this was my first time I figured the dealer under filled last time (though the dash said it was full) or I'd used 1.5 quarts.
There was no sludge or crud in my oil pan.
My Discovery was never privately owned so it was always serviced by the dealer, possibly only one oil change before I owned it.
It wasn't a demo, it was loaned to a hotel.
I filled it with 8.5 quarts of the proper spec oil, drove a few miles and checked the level. It showed and said Overfilled.
I sucked out 1 quart and it showed full and said OK.
So I am happy that it wasn't under filled before and that I hadn't used 1.5 quarts. It appears I may have used up to 1/2 quart (in 8000 miles).
I had drained it until it stopped dripping so that means a drain and fill is only 7.5 quarts and there must be 1 quart that remains undrained.
If you drain your D5 only fill it with the amount you drain then check the gauge.
Next time I'll try the suction method and see how much comes out.
