5 speed Gearbox oil

[Manta 666]

Hello all. I’m sure this topic has been covered to death in the past so I’ll apologise now. I want to change the oil in my manta but get conflicting information when googled! Want to make sure it’s got the right oil in. It’s a 2.0l get exclusive 5 speed. Thank you in advance

Thank you for your replies. Very helpful. Going to get the right oil ordered tomorrow

I believe Classic Oils should be able to help with the correct oil for all your bits and bobs.

Good number mate, ty for that.

the exact specification of the GM is SAE 75W-85 / API GL4, so any good oil that meets or exceeds this specification would be good. 

I think at the time of the Getrag240 release, multi grade oil in a gearbox was pretty rare, so hence why it used to be recommended that only the Genuine was used. But oil technology has come a massive leap forward since the 80’s. As an example, Synthetic can sustain far higher loads at the same film thickness so that the oil is always present between moving parts.

I was looking through a BMW forum a few years/decades ago on the same gearbox fitted to some of there cars and a few members recommended Redline MTL manual oil (Amazon link) for the gearboxes.

Interesting - have you used it?

My gearbox can be a bit tricky in 1st & 2nd in the winter but is fine after a few mins of driving. In the recent warm weather there is no issue. I've wondered if a modern oil would help.

It’s specification is correct, but obviously improved synthetic. Redline does have a good reputation for lubricant in the custom engine scene in US

No I haven't used it, as it was in my list once I got my car back on the road. I have got some GM oil to put in soon, as my gearbox is a little noisy and I hope it will help.

The redline was a back up plan if I couldn't get the genuine GM Oil, as I did spend days checking specs and contents of the oil.

I wish I kept my NATO fuels, oils and lubricant book, as that had all the derivatives of all the oil manufactures and there NATO use, if NATO oil supplies were not available.

Ah yes, hindsight is 20/20 but if we kept everything we’d all need large industrial units, the shed is full enough!

I haven’t gone back through the threads but I think there was a discussion some years back about the GM formula changing too. The old stuff was like it was made from cherries or something but later was different. Anyway I’ll need to search. 
 

Cheers 👍

It’s in a link on my post above for specification of oil.
