Gearbox oil was created by g4vcn
I have changed the oil seal on my gearbox and today i am filling the box but i cant find the correct gear oil in my local car spares. They have 75 w90 but i they only have api gl 5. The manual says i need gl 4. This has been the case for about 4 different places. Will the gl 5 be ok in my box?

Try 80w90 GL4, will make the gearchange a little notchier.

DO NOT use the Comma SX75w90 GL4 synthetic, I have and it is coming out again ASAP.


GL5 contains some deadly additives that can destroy the sychromesh cones this is more of a problem with old gearboxes, but notice Suzuki specify GL5 for the axles and GL4 for the gearbox, there must be a reason...
If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)

I've not used it but noticed difflock sell an oil they say suits both gearbox, transfer box and diffs. Might be worth a try.
