Gearbox oil - grade?

[Epic-Rob]

Just in the process of changing dual mass flywheel in a 2017 manual 6sp 4mo, (bi turbo engine) so i have inquired to VW here in NZ for transition fluid they are telling me 110quid a LITER and i need 3l thats a bit eye watering so i thought i should go elsewhere.
Can anyone tell me the actual grade of the VW gearbox oil? there is also a bit of oil in the transfer case but i am assuming its the same oil?
googling around doesn't seem to find me a definitive answer.

Thanks.

Check out OPIE oils website. They're based in the UK but may well give you a steer on what to look for in NZ.

Hi! I want to change the oil in manual 6speed on my t6 soon. Which oil type should be used, 75w80 or 75w90? I couldn't find the answer on the forum.

75w80?

I've seen this thread already, there's no clear answer about the oil type.

Personally I'd go to VW and buy the exact correct oil for the gearbox. The VW oil is very good, and there have been a few stories of people putting aftermarket oil in and regretting it, as the gear changes weren't as slick.
Seeing as this oil change is never done on virtually every gearbox, ie it's filled for life, it's a very long term investment, so worth spending the money!

75w is an oil type (as ahown in the table). Where have you seen that it should be multigrade?

It's always either 75w80 or 75w90. Both are available and shown as suitable for my van on multiple websites of car parts companies. I'm sure that there is a difference. I've seen posts where some ppl use one type and some use another one. I opened a thread here to discuss this and maybe someone knowledgeable can say something about this. Seems like both types work. But are both good for long run?

VW oil is either 75w80 or 75w90 and gl4. They don't state it on the manual for some reason. If oil meets certain norm and is certified then it's good, doesn't have to have VW badge on it. And the VW oil costs 6x the price of same oil that isn't made for VW. It's worth saving for me as that's a lot of a difference and I'm doing everything in my van - all liquids, lights, seats, suspension, brakes, paint, upgrades for performance etc. If I have to use genuine parts everytime then I would pay x times the value of the van

Unless it's 75w 521 71 spec as suggested in the link above...One example : Mobil 75w GL4
Halfords, GSF, Euro car parts all list oils with the above spec when I type in my number plate and it's been in my manual 'box for 50 000 miles so far with no issues...

Out if interest, where have you seen multigrade recommended?

The oil spec isnt in the manual as the gearboxes are "lifetime sealed" and don't require servicing. That's a load of cobblers of course...

Then parts man at rhe dealer will look it up on his magic piano for you if you ask nicely.

Online car parts, Autodoc, euro car parts, spare parts (European parts selling sites) and also ppl on European transporter groups recommended different type depending on country in the UK mostly 75w80 is recommended but there's also ppl who used 75w90 and are fine. Both 75w80 and 75w90 can be GL4... Pictures show just some examples.

And most of those sites also "recommend" 75w...
If you're desperate to use a multigrade, pick 75w80. Unless you routinely operate in higher than normal temperatures, I can't imagine the need to go for the slightly higher rated of the two.
Or just go to a dealer if you still can't decide. If they can confirm exactly what oil we should use and why, you can draw a line under this longstanding query.
