Gearbox Oil 80w90 Can I use it?

[kiwiNCFC]

I was rooting around in my garage the other day and I found an unopened 5l bottle of valvoline 80w90 gearbox oil. I think my mate might have given it to me when he sold his corsa.

I had a search on here for what type of oil you use in a 182 and the general consensus is to use 75w90.

Is there much difference between 75w90 and 80w90? Would it be OK to use?

Cheers!

You should be okay with that assuming it meets GL4+

Ok thanks. What is GL4+? I had a google to no avail.

Its the specification standard and will be on the back on the bottle somewhere

I've used it in boxes that have started to crunch, usually delays the inevitable box change for a while

Cheers guys!!

Also, 80w is not as fluid at cold temps as 75w, so in the cold winter months you may find the gearshift baulky untill the box warms up.
