Gearbox oil recommendations.

I’m going to change the gearbox oil in my 90 clipper five speed manual.

Having ordered the 17mm hex socket I  need to order 2 ltrs of oil but which type would be
better suited to a vehicle that’s done  104,000 miles ?

Thanks

The driver's driveshaft flange seal started leaking a few months ago on my 1983 Cab Gti 180k miles.

Changed the gear oil after doing the seal using Morris Lodexol Gearbox Oil 80/90w from heritage, about 1000 miles done since, all good.

Thanks for the recommendation which one of these did you use?

I got the 5L one:

VW recommend GL4. GL5 can apparently be corrosive to synchromesh systems, due to the high level of additives

Thanks guys I’ve ordered 5 ltrs of GL4.👍

Really appreciate your replies.

5L. it only takes 2L to refil a manual.

Yes I was going to buy 3L so I had some spare just in case of spillage / top up but it worked out cheaper to buy 5L with postage included £37.30 Just drained the gearbox and removed 2.3 Ltrs of old oil so whenever it was last done it was overfilled guessing probably when I had the clutch changed Now I’m going to make something to use as a filling pipe/tube thingy

If you can "Easily" remove your Speedo cable, you ca top fill with but a long spouted funnel.

On the gear oil that I used there was a spout on the top, to that I affixed a vinyl  tube once,

On a side note if you place your oil in a pot of HOT water for a few minutes, it will be easier to pour.

Notice I said "IF you can Easily remove your speedo cable" as it can be a PITA to remove so take care.

Some like me never had an issue removing the Speedo cables on  my 81 diesel Golf's 4 or 5spd transmission for 20 years, and my 90 Cabriolet.  I did tend to Jack both wheels up, place in 1st gear and spin the wheels forwards and back wards a bit to release any gear bind just in case, or I was blessed with nice cables.  

On my 92, and 93 cabbies they were Auto's and that is a horse of a different color.

Thanks for the tip Briano1234 re warming the oil prior to filling 😎
Hopefully I've made a funnel extension
 (don't laugh too loud )😂😂😂



Fingers crossed it works 😳
