2012 Mini Cooper Manual MTF-LT-4

[thezfunk]

I would like to revive or pursue this discussion further: https://bobistheoilguy.com/forums/threads/specs-on-bmw-mtf-lt-4.309550/

I have a 2012 Mini Cooper that fell into my lap and buying some Amsoil to replace all the fluids. However, I get to the manual transmission oil and Amsoil says they don't have it.

(1) To determine the correct gear box oil, check the sticker on the transmission. Manual gear box oil MTF-LT-3 is marked with a blue sticker. Manual gear box oil MTF-LT-4 is marked with a yellow sticker. Do not mix MTF-LT-3 with MTF-LT-4. (1) To determine the correct gear box oil, check the sticker on the transmission.

Based on what was discussed in the linked thread, it seems like Red Line MT-90 might be a good option. I am fine with that. Also curious if either of these Amsoil options are also a good choice.

I’ve used both and both are fine.

Spec is 75w90 GL4 classic ZDDP, so RL MT-90 is best match. Amsoil 75w90 too but different additive.
Classic Motorcraft/Ford 75w90 XT-M5-QS (Castrol Multivehicle 75w90) are good GL4 ZDDP too.

This thread may be useful (has the VOA of LT-4 too) :

Update: Since Castrol Syntrans V-FE and Syntrans Multivehicle are difficult to obtain and/or more expensive than a couple of months before I placed my order on OE BMW MTF LT-4. Should be here in a few days. Hope it'll resolve the shifting issues.

And this is the VOA of Ford XT-M5-QS 75w-90 GL-4 mentioned above (aka Castrol Syntrans Mulitivehicle 75w-90 / Volvo 1161723 / European Ford 75w-90 BO (1790199) / Castrol BOT 130m ) :
