u/Mike-875

Hey everyone,

I have a 2021 Peugeot 508 1.6 PureTech with 130,000 km. I believe the gearbox oil has never been changed. Now, I'm trying to decide if it's a better idea to leave it as is or to go ahead and change the fluid.
Peugeot claims that the fluid is "sealed for life," but Aisin, who obviously builds the hardware, recommends servicing it.

So, do you guys change the fluid? If yes, how did you do it? A partial drain or with a mechanical flush machine?
