Ford Motorcraft Full Synthetic Manual Transmission Fluid XT-M5-QS VOA

[Rollins]

Seems like
-Ford's Full Synthetic Manual Transmission Fluid XT-M5-QS ( WSD-M2C200-C )
-European Ford 75w-90 BO (1790199)
-Castrol Syntrans Mulitivehicle 75w-90
-Volvo 1161723
is the same Castrol made fluid (the renamed Castrol BOT 130m )

API GL-4
Ford WSD-M2C200-C
MB-Approval 235.72

The PAO based formulation has not changed much (these are two UOA I could find on BITOG for comparison). Looks like the oil shears down to low SAE 85 viscosity very fast .

Ford has contracts with BP Castrol and GM has contracts with PetroCanada to blend fluids for various applications.

Then you you have the Botique blenders such as Amsoil and Redline who make equivalent fluids such as

Amsoil 75W90 GL-4 MTF

Redline 75W90 GL-4 MTF

and of course there are similar products as well such as:

ACDelco 10-4059 GL-4 75W-90 Manual Transmission Fluid
RAVENOL TSG SAE 75W-90
LiquiMoly 75W-90 GL4
