I've just run through my first litre of FTC over roughly 12,000 kilometres in a TDV6
Commenced using it at about 175,000k and now up to 188,000+ k.
Recently the torque has increased quite noticeably - engine power seems much the same - it'll still blow a diesel cloud under hard acceleration but under calm conditions there's little sign.
Vehicle is running at lower revs, shifting down gears sooner, and holding longer before kicking down on inclines at road speed.
Fuel consumption has improved by about 10%
After discussion with a diesel mechanic I'm attributing this to the turbo running cleaner - it seems to be the 'variable vane' type so decarbonisation may have cleaned up the turbo leading to better turbo response - hence increase in torque with lower revs.
Engine is definitely running sweetly, with excellent response, and seemingly 100 to 200rpm lower across the speed range but really noticeable at highway speeds and up hills.
