I tend to use Castrol, other than the gear box where I use Land Rover MTF 94. I have tried 75w 90 but in the winter I find it effects the gear change. Living up North this is an issue. Have a look at the Castrol site, I have found them to be very responsive https://applications.castrol.com/oilselector/sv_sv/c/search

You do not own your Land Rover, you just maintain it for future generations.
