Magic not Snake Oil
Ordered 2 tubes for my car gearbox. She has noisy input bearing, I know it didn't fixed the bearing, I just bought some time and noisy is 80% down, worked like a charm for me so far, finger's crossed. P.S. smoother gear shifting too Love it.

Watch it run...
Have been aware of the properties of MoS2 as a slip/wear additive for some time. Bought with the high performance gear oil, after a rinse out with neat oil was able to just pour this in, literally, followed by fresh oil, easy. Performed an oil change on an older strimmer powered cultivator, couldn't have been easier, sounds so much better, and runs freely too. Gears look clean, and holding a nice film.

Will Need Multiple
You'll need to buy more than one unless your gearbox only holds 1 litre of oil. But it seems to do the trick.

It works
My old land rover series 2 could get a bit awkward to select first when gearbox was hot so I thought I’d give this additive a go , I’ve left it a few weeks before I left a review to see how product preformed, it has made a big difference to the gearbox much better gear change in all gears so very pleased , as any owner of a old series landy knows the gearbox’s can be a bit tricky!!!! So to sum up for me it worked so very pleased.

Kind of worked... for a while
The gearbox on my car has occasionally been a little difficult to change from 2nd to 3rd specifically but overall the changes are "notchy". I changed the gearbox oil around 18 months ago which helped a little then added the recommended amount of Liqui Moly as directed on the instructions. It helped a little for around 2 to 3 weeks then reverted to how it was before. I changed the gearbox oil again at the weekend and had some spare which I used to flush out the old stuff before re-filling with fresh new oil. The state of the old oil, with the Liqui Moly, was awful; black, sludgy, had creamy white tinge (like water had been present)....... not nice. I then added the fresh new oil and it's slightly better. Overall, product wasn't really worth it.

Un producto magnífico que disminuye ruidos de la caja de cambios, suaviza el cambio de marchas y mejora el rendimiento.

Das Additiv ist der absolute Knaller. Ich habe zwei kleine Tuben in das Getriebe des Fiat 500 zugegeben und es lässt sich butterweich schalten. Ich kannte diese Additiv bereits von früher, da wurde es dem Getriebe des Golf 1 zugegeben, da es sich aufgrund von Temperaturerhöhungen nicht mehr schalten ließ. Nach der Zugabe, man kann es kaum glauben, war das Problem dauerhaft verschwunden.

Pour lubrifier la boite je pense necessaire après vidange pour maintenir une qualité d'huile neutre. Aucun soucis rencontrés niveau efficacité cela a arrangé les vitesses qui accrochaient un petit peu mais je n'avais pas de gros soucis. Toujours bien à utiliser. Bon Produit de bonne marque à bon prix.
