For normal climates, any 10w30 fully synth oil will after 600 miles onwards (I would use 4-stroke motorcycle oul but as the pcx has a dry clutch, normal oil will do for the engine and Final Drive!) < it does not need to be special oil for the final drive.
You don't use oil for brake fluid, just get a good Dot 4 brake fluid (sealed is best, not good to use very old and opened brake fluid).

When I had my 2017 PCX 150 I bought the Honda HP4M oil at the Honda Dealership. It's a bit more expensive but I felt it was justified.
I put the HP4M 10W-40 in the crankcase and the HP4M 10W-30 in the final drive. It's a synthetic/petroleum blend both "MB" and "SJ" rated if I remember correctly. It contains "moly".
Considering my climatic conditions (northeastern U.S.) it worked for me . . ..
I concur with Iceman otherwise and about the DOT 4 brake fluid.

You can use any good nike oil in the rating range for the engine (fully synth) and final drive - you do not need the 'moly' oil or such - it's a dry clutch not wet. Scooters are one of the most common bikes around and are pushed heavily daily - look at all those pizza deliveries and commuters - they use normal oil and in many cases car oil.
If you can easily get the special moly oul then fine, it's very good oil, but in many countries you cannot easily get it - my Honda bike dealer sells and uses Castrol 4-stroke fully synth for Honda scooters!

Recommended Honda oil.....having said that...been using Walmart Fully Synthetic 10w30 in my PCX crankcase and final drive.
At 59k miles currently.

Absolutely any 10w30 motorcycle oil (or oil for petrol car engines) is the correct oil for both the engine and the final drive.
"HP4M" is the brand name of a Honda oil product, you can ignore "HP4M".

Do you have the owners manual? The final drive is at the rear axle with a small reservoir with oil for the gears.
There is a fill/check bolt on top and a drain bolt at the bottom. Surely a search on this forum should help.

Correction.....the fill bolt is on the side, above the drain bolt. There are two bolts right next to each other. The left one is the fill.
[Right one secures the parts together.......no need to tamper with that one]

As usual, Homie's videos are super, see the later part where he identifies the final drive fill, drain, etc plugs.

by you you
I popped a little paint on the fill and drain holes so I don’t need to double check which two bolts out of the three bolts in that area I need to remove.
