Don't use synthetic for sure...
The diff takes a hypoid bevel oil iirc... There is an equivalent available for the factory spec... It's been a while since I did mine so can't recall off the top of my head.

While on the subject...
Every pump I have bought is a pile of crap. I finally put a long tube through the boot vent hole into the rear end. With no lift and not much patience it's less on the floor and les crap in the eye balls...
But the transmission is another challenge, as there's no convenient ho and same crappy pump problems.

Tigers don't have a hole on the passenger side. There's a removable plate on the driver's side for adjustment of shift linkage. I suspect that I'll try a longer tube and a higher gravity feed.
It took a couple of pumps to get to this stage. I talked to a fellow Tiger owner and he in person motioned at how high he places the fill bottle.
And yes it can be like molasses in January , even though I have never seen or used molasses in January

I put a shiny brass key in the GL5 oil. I left it in there for over a year, and it looked like the day I put it in. Don't miss the "Oil Expert." He's busy trolling MK on another forum. But I hate to "" him but he espoused that they put additives in the GL5 to not hurt yellow metals.
"Our specialty formulation is yellow metal safe ... "

As far as I'm aware no brass in the rear end...
I know that there is in the trans.. same in the trans on the Tiger.. so have to be careful what oils you put in..

I went through my series V rear axle. (The pinion seal leaked, and I was scared by some rear end's having loose ring gear bolts....) I used Amsoil Severe Gear 80W-90. I have used that lube in repairing gears (professionally) since about 1980. Anyway, new differential bearings are set up tight, the pinion turns at 20-25 inch-pounds of torque, and so new axles can get hot while breaking in. That lube, first time I used it, kept the new axle job cooler to the touch than I had ever seen.....I trust it. Here is a link with data, including ASTM D130 test for copper (alloys like brass) corrosion. https://amsoilcontent.com/ams/lit/databulletins/g2043.pdf

I like the "leave a brass key in the oil" test.....Turns out, there is a lab test for that. ASTM D130 puts a polished copper strip in the test lube for three hours at 100C (or 50C for fuels). The rating for my favorite gear lube is "1b" which means the polished test strip has a slight tarnish.
