Better than Stock
Installed after changing my valve cover gasket which leaked 6K miles later due to warped valve covers. 10K since installing it no leaks. Doing great.

A+ Does what it claims to do and does it WELL in reducing gear noise and making smoother operation
I have used this on 2 older cars with manual transmissions and now on my older motorcycle. They ALL had noisy gears with the typical WHINE while under load which was very loud! This did exactly what it said is would do and within about 150 miles all the transmissions got a LOT quieter! i have continued to drive adding thousands of additional miles and they are STILL staying quiet. On the motorcycle, since the oil is for BOTH the transmission and the ENGINE? The engine stopped burning oil and ALSO got quieter and smoother!

Quiter without affecting shifting
I've been using it for about 4 years, and change the gear oil every 2 years.

even better than the friktiontek
even better than the friktiontek. This bottle is more than enough for my 5 speed, was instantly smoother and more accurate. I am anxious to see a mileage increase.

Big LIE & unsupportive seller
Don’t waste your money hoping this fluid will somehow fix your transmission. It would elicit the same affect as when you spit inside your transmission. The seller would suggest to buy more of their spit when the initial product doesn’t work.

OUTSTANDING OIL ADDITIVE
After installing and driving my 05' Pathfinder & 05' Chevy for nearly 1000 miles, my vehicles are performing like I had a new tune-up. XADO is the top secret of the automotive industry.. Its much better than Z-MAX

即効性あります

Es wirkt wie erwartet
Verpackt kam das Produkt genau so, wie es auf den Bildern zu sehen war. Da bei dem Benz meiner Ma das Getriebe sehr hakelig zu schalten war und ein Getriebe-Öl-Service sowieso anstand, entschied ich mich dem Additiv eine Chance zu geben. Das Getriebe ist ein 5-Gang-Handschalter. Dies wurde gespült und mit frischem Öl samt dem Additiv versehen. Die ersten 200-400km merkte man nur einen sehr diffusen Unterschied. Diffus deswegen, weil sich die Geräuschkulisse nur wenig änderte, aber das schalten selbst nach und nach leichter wurde. Nach nun guten 2000km kann ich sagen, dass es sich gelohnt hat. Die Schaltvorgänge laufen wieder schön geschmeidig ab, keine Zahn-auf-Zahn-Problematik mehr und auditiv kaum mehr irgendwelche Geräusche wahrnehmbar. Dies ist auch meiner Mutter aufgefallen, welche normalerweise für solche Themen kaum ein Gefühl, geschweige denn Ohr, hat. Kleiner Hinweis am Rande! Sollten Teile des Getriebes zu stark verschlissen sein bzw einen Ausfall nahe, kann dieses Additiv auch nur wenig daran verändern!

Ideale per le trasmissioni manuali
Ho una Yaris D4D del 2010 con cambio manuale 6 marce, dopo aver usato un olio appropriato (75w GL4) e questo prodotto della XADO, sembra di guidare un'altra auto, cambio sensibilmente più morbido e dolce negli inserimenti, migliore perfino di quando era nuova....questo prodotto è l'ideale per le trasmissioni manuali.

No pudo hacer nada, pero lo echaré de nuevo.
Lo eché en un Seat Altea, junto con valvulina nueva, porque sonaba la caja de cambios, después de 300 km la caja murió por culpa del rodamiento doble, como podéis apreciar en la foto. Cuando monte el cambio con un nuevo kit de rodamientos le echaré la misma valvulina que saque, pues está totalmente limpia, sin ningún rastro metálico. Espero que vaya bien. Haré una nueva reseña. Después de haber puesto los nuevos rodamientos y retenes del kit de reparación en la caja de cambios, le eché la misma valvulina que había sacado. Y va perfecta. No suena nada porque los rodamientos son nuevos, pero va muy suave y pasan las velocidades muy suaves y eso creo sea debido a la valvulina y el aditivo. No puedo decir más.
