⚙️ Upgrade your gearbox game—silence the noise, feel the smooth!
LIQUI MOLY Gear-Oil Additive is a high-performance lubricant enhancer containing MoS2 that forms a durable film on sliding surfaces, reducing wear and noise in gearboxes, driveshafts, and differentials. Designed to withstand high thermal loads, this 20g additive treats up to 1 litre of gearbox oil, improving gear shifting smoothness and extending component life. Ideal for professionals seeking reliable, long-lasting gearbox protection (not for wet clutch motorcycles).

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.

Seems to work well
Recently added this to front/rear diff, gearbox and transfer case after changing the oils and it seems to help with noise reduction not sure long term effects yet but it does turn the oil a metallic silver when draining it as my rear diff had some in it already that I put in when I got the vehicle so if you use it and take it somewhere to have the oil drained and changed be aware they may bring that up

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.

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.

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.

Muy efectivo
Tenía un poco de ruido en 5 y 6 marcha. Luego de unos 40km de uso ha disminuido en un 80%. Realmente funciona. Recomiendo

Bien
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.

Absolute Spitze vor allem wenn das Getriebe stark hakelt.
Ich hab mir das Additive gekauft wegen der guten Rezensionen. Und ich muss sagen ich bin echt beeindruckt. Bei meinem A4 1.6 hatte das Getriebe immer gehakt obwohl erst vor 30000km das Öl und die Kupplung gewechselt wurden. (Zumindest laut Quittung vom Vorbesitzer) Ich habe jetzt das Getriebeöl getauscht und gemerkt das etwa 1l Öl zu wenig drinnen waren. Hab jetzt 2,3l Liqui Moly 75W-90 und 80g von dem Additive eingefüllt. Und siehe da nach ca. 500km hauptsächlich Autobahn lässt sich das Getriebe Butterweich schalten und ist wesentlich leiser geworden. Ebenfalls hab ich die Bremsflüssigkeit an der das Kupplungssystem mit dran hängt auch getauscht.(War schon 4Jahre drin) Fakt ist das er sich viel besser fahren lässt. Kann ich nur weiter empfehlen. Kaufe ich wieder.

Butter smooth gear shifts
Very good product. 2nd purchase in the last 5 years. Has definitely made gear shifts totally smooth.... So smooth that I can actually shift gears with just one finger. Using it in my Suzuki Ignis with manual transmission. Definitely recommend.
