Hi all.
Need to top up my gearbox oil and having done a search, it appears i need 75w90 gl4 gearbox oil. Been to a few local motor factors and there oils say they are gl4 and gl5.
Can't find gl4 alone. Is the other stuff no good? If not where have people purchased it from
Thanks
Steve

Halfords sell both Comma and Halfords branded GL4 oil.


With the exception of GL5 oils Rwd gearboxes generally can happily use most oils including 5w/40 or 10w/40 engine oil and automatic transmission fluid.

comma sell 75w90 gl4 on amazon for under £6 a litre delivered.

and BGH recommend the Comma stuff for there boxes (even the top spec ones) - so its more than good enough

Thanks.
Hadn't even thought of amazon.
Now ordered

Used comma in mine. All good

Don't use GL5, contains additives that damages bushes and synchs iirc.

I had this reply from Quaife when I asked,..

GL5 will be perfectly fine in a Type 9.

If I can be of any assistance in the future please don't hesitate to contact me.

Kind regards

I do hope that he is right

that might just mean a quaife type 9 gearsets - they replace all the bits that are affected afterall


GL5 will kill a standard type 9 synchro's after a while
and the ones that claim to cover both GL4 and GL5 are just as bad...

its to do with the material the bushes and synchro's are made from - anything with GL5 spec. will damage 'yellow metals' like brass etc. due to the much higher levels of sulfur/phosphorous additives in the GL5



just use this stuff - its the perfect spec for the type 9 and its cheap too
