Looking back at a service checklist for my +4 from a well known dealer, it says
Gearbox oil: replace only if older model or if requested by customer
Axle oil: Change at 100,000 miles or every 4 years.
Axle takes 1.7 litres of 80W/140 Semi synthetic Syntrax (now appears to be replaced by “Transmax 75 w 140”)
Gearbox: 1.7 litres or maybe a bit more of Morris Lodexol FS 75W90
