Still on a bit of a learning curve, so forgive a possible repeat offender question.......

My Haynes manual calls for SAE 90EP oil for pretty much everything except engine, clutch and brakes.

Sooooo........which one of the pentrite gear oils fits the bill, as I don't want o have to use 2 different oils, on the basis of 'keep it simple stupid'

You HAVE to use 2 different oils (technically 3 including the dot4 for the clutch and brakes )...unless you want to cook the diffs and boxes...... That's why manufacturers give us the specs :doh:

SAE90 is a standard hypoid gear oil for diffs and gearboxes - a simple search in the website will point you towards an 80w-90 hypoid oil for the diffs and gearboxes.

Make sure it's a GL4 oil, many are now GL5 which may corrode the phosphor bronze components of the gearbox. GL5 should be OK for diffs, swivels, steering relay and steering box.

Not sure where you're coming from Dirtyrhino. First you say use both types then you suggest just one? Whaddya mean?

As I mentioned before, the Haynes manual suggests SAE 90EP for the diffs and the gearbox, but the Penrite website gives one oil type for each.

(So the manufacturer (well, Haynes in this case) has suggested one oil for both the diffs and gearbox, whereas Penrite is offering 1 different oil for each).

So with this in mind (and Oxides' comment about GL 5 grades), I reckon the 'manual gear oil 80' is the go.

Any suggestions????

That's probably the one. The website selector leads you to their "Mild EP gear oil" which looks a bit thick to me and I bet it's more expensive.
