Hi Nick,

I have been using Penrite Mild EP Gear Oil. Has been working well, for the past three years.

Nothing to worry about . Just ordinary 90 grade gearbox oil .. you can get it anywhere . There were issues with modern hypoid oil eating bronze washers in older vintage car diffs..but our Rovers have no issues there .

The brakefliud is ordinary off the shelf stuff . dot 3 is OK .

You will have problems bleeding the brakes, its a Land Rover thing . Awfully difficult .

Hi Nicholas

I have seen electrolysis damage done to the phosphorus bronze bush and I did use EP 90 oil in that gearbox.

Try a straight 90 grade mineral oil without the aluminium oxide additive (EP), in the gearbox, EP 90 should ok everywhere else.

x2, Dot 3 is good.

Reverse bleeding the brakes, works well on Land Rover's, including the Series one's.

Cheers Arthur

You may struggle to source EP 90, EP 80W90 is more readily available and equally suitable.
You can get this from Autobarn, Supercheap etc. most manufacturers have it in their range (Shell, Mobil etc.). About $40 for 5 litres.
The Dot number of the brake fluid relates to it's boiling point, as cars get get faster & heavier the temperature the brake fluid has to resist increases. Dot 2, 3, 4 or 4plus will be OK (the higher the number the higher the boiling point) but be careful with Dot 5 (silicon) as this doesn't mix with the others.
Dot 3 & 4 are readily available at most autoparts shops.
