I have a 2011 diesel Mondeo with 260000 km on it now and have been using penrite dct fluid. It's still changing gears smooth and it is very easy to do yourself. All I do is undo the two drain plugs to the transmission drain the oil then put the plugs back in change the filter and take the air cleaner box off and fill oil from the top of the transmission. I change the oil every 60000 km and the transmission has been faultless highly recommend the penrite dct fluid Ford Mondeo dual clutch transmission.

Transformed my 2011 mondeo diesel dct shifting from rough to buttery smooth. Paired with genuine ford transmission filter. More than happy with result.

Seemed the last mechanic had skipped the filter change so guessing he likely used sub optimal fluid too.

The Penrite DCT is well worth the expense but make sure you or your mechanic knows the very fussy filling procedure required for the mondeo transmission.

Required just over 6 litres including wastage from filling procedure. Bought 2 x 4 litre tubs at $70 each from Autobarn plus filter $42 from Ford.

Cooked the Mondys Trans fluid after only 38K from new as I fitted Fly Wire to my Radiator to stop the Bugs, Cut a long story short the box was stuffed advised by my Ford Dealer and was going to cost 9K to replace it !! Having picked myself off the floor decided to attack the issue myself ! The trans oil was Black as when drained causing the issue, Did 3 Flushes through with the Penrite DCT and replaced with Ford Gen oil filter For trans box ! Its FIXED!! Awsome and no 9K to replace Transmition, its a bit tricky to drain and change but info on UTUBE Fantastic Product has been expensive exercise but a fantastic Result

I replaced the dual clutch transmission oil with Penrite DCT fluid, in my 2011 Ford Mondeo diesel. The fluid was changed in November 2016 at 113,000 kms.

The transmission was always very rough, the gear changes very uncomfortable and a noticeable delay between touching the accelerator and the vehicle actually moving. The new oil has fixed all these problems and the transmission runs perfectly. The previous problems could be due to the age of the old fluid and the fact it was not filled to the correct level.
Update June 2017 123,000 kms. Still runs flawlessly.
Update November 2018 135,000 kms. Still runs flawlessly.
Update May 2022 140,000 kms. Still runs flawlessly.

I will update this review periodically.
