I have a Megane RS MK4 2019 plate. The car is running the PK4 manual gearbox thats in the previous RS model (MK3) thats known for issues.
My car has 10k on the clock recently im getting clicking/knocking at 35mph. Any gear, neutral, clutch in or out. The car drives perfectly and goes into all gears perfectly. The noise is either the LSD bearings or the output shaft bearing. I wont know for sure till the gearbox specialist gets inside the gearbox and looks.
I want to put the best possible oil in the car when the gearbox is fixed to hopefully stop this happening again. The OEM oil is "Elf Tranself NFX SAE 75W". However this is the newest version of the oil it was formally known as "ELF TRANSELF NFP 75W-80"
Iv been looking online high and low for my options and i came across a guy that tests oils out using a machine and one oil caught my eye "Total Traxium Gear 8 75W80". Im going to link below what im talking about.

The difference of these two oils is clear on these videos. The stuff that's suggested for my gearbox seems to be rubbish.... The specs of both these oils match as far as i can see. However my car has an Torsen LSD and iv been reading about friction modifiers etc. I have no clue if this Gear 8 stuff would be ok to run in my gearbox because of the LSD. Also i have no clue about additives etc... There is also a company called K-Tec who are big in the Renault Sport world and they have suggest Millers 75w-90 to people instead of the OEM stuff thats w75-80. Im lost, i want to prevent myself from having thousands of pounds of bills again. Also the car has brass synchros if that makes a difference to oil options.

I know there is more to oils than just the tests iv shown in the videos... and im no expert here.... Do i just stick with OEM oil or can i go with something like the Gear 8?? Its weird how its such a common issue on there gearbox's, im hoping i can boost my protection with a better oil choice. Cheers
