you might want to have a paint roller tray to hand, plenty of paper towel, some allen keys to get the nut undone, and short sleeve t shirt. thin rubber gloves, you will get a bit messy.
as pepte says, dont take the nut off till you have fully warmed it, and primed through the gears. otherwise, it will be all in the sump, thus it will gush out.
-all down your arm, and on the floor etc.
one tip, place an old flannel on the exhaust next to your work area. to save getting burns.
its quite possible to do the job, with car on a flat drive, in offroad mode, crawling underneath, however, on a ramp, of course, its much better.

Cheers for that, looks like I'm gunna get messy when oil turns up. Lol

And there is little room to get a bottle above it to drain into it so it's squeeze it like mad or use a pump garden sprayer or similar.... Pete
I now have permission from the boss to use Y.O.L.O. Enjoy life

The pump garden sprayer works a treat , I cut off the spray nozzle and cable tied a short length of garden hose to the pipe and that fits neatly into the filler.
As mentioned already , trying to fill from the bottle is very difficult as you can't raise the bottle up high enough to get the fluid out. The first time we tried an oil syringe but the oil leaked back past the plunger and we were drowning in oil to the extent I thought greenpeace would show up.

Lol. Holiday chicken.
