Well I’m surprised that can’t find MTF94 spec oil in Hungary i’ve seen it in various countries I’ve visited.
The “Genuine Rover/Land Rover stuff that u can purchase in their parts department is just rebranding of the Texaco item which is a basic 75w 80 HD mineral transmission oil that’s been around for years, since multi-grade started to be a commonplace oil.
So MTF95 is something that other oil producers have, I use it in the gearbox of a Ford car that I’ve owned for the last 43 years without any issues in gear selection or leaks.
If you wish to pay the inflated prices of oil and other consumables from a Main Vehicle Dealer or a supplier of them, so be it.
Of course there’s synthetic MTF94
