I very rarely leave a review but when something works it's worth letting others know. I added this to the gearbox of my Renault Laguna 2.0 dci GT... I added it when I changed the oil in the box.... I recently bought the car and with the mileage being 74k the likelihood is that the oil in the box had never been changed... gear change was ok slightly notchy but not at all bad....I drained the old oil and added this in two bottles and mixed it up... without doubt the new oil helped but this stuff made the gear change smoother still... I now only use Liqui moly products... I have recently used their diesel and injector cleaner and also their throttle body cleaner... all of which worked brilliantly... especially the diesel injector cleaner... I had a rough idle problem and it completely cured it... Liqui moly is slightly more expensive than some of the other more well known brands but it's German liquid engineering that actually works... I would just like to add that I do not work for or receive any financial reward from Liqui moly for my reviews... but if they want to then please feel free!.. lolRead full review

Before using this product Gearbox was noisy on overrun and notchy gearchange. After a few miles noise has reduced and changing gear really smooth. Product cheaper than the Molyslip but works just as well. Will purchase again when required

It has turned a stiff hard work gear change into smooth effortless one

I am usually very sceptical about things like Gear oil and Engine oil additives because generally they don't work. But this one actually does work. The gear change is noticeably smoother on my classic Ford Escort after adding a 50ml tube of Liqui Moly to the gearbox oil.

Always use when changing a oil in gearbox every 5years or 40.000miles the gearbox is quieter. The gears are easier to change
