My 166 has the tray as well which I made the mistake of taking of before changing the oil.
I think you can get away with leaving the back two bolts on and put your used oil tray/basin on the actual tray.
The 166 has an 8mm allen key sump nut.
Cherb at least 15mm is an odd number (as opposed to even not strange).
My wife has a 97 Primera which has 12mm bolts which drive me mad - trying to remember if there were other awkward sizes...
Generally find 8, 10, 13, 15 (less common), 17 and 19mm are the most common sizes...
Re type of oil: I've been using Castrol Magnatec which Gerry in TI also likes...
Say no more...
