Just changed mine yesterday on my 8v, dont know if thats the same as yours?.
But it is pretty easy.
Undo drainage plug, put a bowl under it. wasnt too messy in my case. the hole is near the bottum?.
undo filler cap.
tighten up drainage plug, it has a tapered thread on it, so dont tigthen it insanely hard, else you will damage the thread(torque wrench would be good.. but the wishbone is in the way, so cant fit any big tool.. atleast i couldnt).
Fill in 2liters (workshop manual states until it reaches the lower edge of reverse light switch hole, but filler and reverse light switch are about the same hight.. so.. but just fill in 2 liters).
screw in filler cap.. job done
And about getting the oil in, my oil bottles had a built in funnel thing, made it easy.. but yeah, guess you can join a hose and small funnel, if yours dont have that.
hope i helped.
