Hi can someone confirm the correct oil for gearbox. I am going to change it when I get chance. It’s a 508sw 2012 2.0 Manual diesel. I have ordered some but just need to check it’s correct.
I’ve got some total gear8 oil. 75/80 specifically mentions suitable for PSA gearboxes.
I’ve ordered 2 litres. Is this enough ?
I assume it’s fairly simple.
Jack up. Check can remove the filler.
remove the drain plug. Leave it for a while. Replace plug and fill till level with fill hole ?
many thanks if anyone has any advice.
thanks.

You may not have a filler plug it was deleted on later models (save a couple of pence per car as filled for life lol). So you have to drain and fill with measured amount of oil via breather.

If it's the six speed box it needs 2.2ltrs according to service box info as I have just ordered the oil to change mine when I replace the clutch in my ds

thanks. Yep had to fill via breather. 2 litres came out maybe a touch less I put 2 litres back in. I guess there will still be some of the old oil in there.

what kind of oil use 5 speed boxes on puretech 82....?
psa norm? viscosity? gl4/5 ?
anything specific?
i´d like to use motul, do you know which ?
-thanks-
The current "spec" for all manual boxes made by PSA is: PSA B71 2330.

The oils PSA specify (Total Transmission BV, Mobil Gear Oil FE, HBVFE2) are generally 75W80 GL-4+

thanks people
i read this means beyond gl4 but not fully gl5 level. (full gl5, should chew the syncros:()


comparing these two badboys, motul being a hair more viscous.
anybody feels 3rd, 1st gear sometimes being little harder to push in ? (26kkm on clock)

I have found almost all other grades or makes of oil result in stiff gear changes when gearbox oil is cold especially in the winter

interesting. some specialist on bitog oil forum said, the gl4/5 will have a hair higher viscosity in same W grade, compared to gl4.
he says this can increase effort to shift when cold. otherwise all good.
the gl4/5 has more antiwear additives, compared to virgin gl4.

I changed mine because gear changes were getting abit stiff especially when cold and the car has done 160k miles so thought for the price of the oil I’d give that a go.

regarding autotranny is better to visit service. they can pick correct oil according to vin.

when you change only 30% of content...the old 70% of old oil remains. (better than do nothing...though)
if google-fu is correct: aisin AWF8F35 8° norm JWS 3324
