Who is running what for gear oil?
GL-4 vs. GL-5? does it really matter that much over the life of the transmission?
I just switched to synthetic but even with new gaskets and plenty of Hylomar it seems to have sprung leaks from everywhere!!
...yes i know it's a Land Rover, but at least with the 'crude' it would only leave little drops to mark its territory, now it looks like it pissed its pants if I drive it more than 10 miles!

any suggestions?

Yes, clean oil tends to get through smaller holes.....

Whatever is on sale in a 5 gallon bucket at Pep Boys, the best gear oil is the one you change most often.

In the gearbox(s) I use GL4 from NAPA. There is a longstanding opinion that for old UK cars GL5 will damage bronze parts - I think I cause more damage by poor driving but haven't wanted to take the risk of using GL5. I think that you can use GL5 in the diffs/steering box/relay/swivels.

What Peter said. Although, it was near impossible to find any GL4 locally (Frenchtown), even with the NAPA p/n. I did find a Penzoil distributor, and picked-up 15 gallons (3 buckets). I haven't quite worked my way through on of them yet...

I'll post the Penzoil order code shortly.
