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

Sehr empfehlenswert
Das Zeug ist der Wahnsinn, habe es in mein Getriebe gegeben weil es im 5. Gang sehr laut im mittleren drehzalbereich war und jetzt schon nach 500km ist es deutlich leiser geworden ich habe natürlich vorher das alte Öl abgelassen und neues Öl eingefüllt mit der richtigen Menge und dann diesen Zusatz hinzugefügt, würde es sicher wieder kaufen wenn ich wieder einmal Probleme mit dem Getriebe habe

よく分からん (追)素晴らしい
多少良くなったかな、とは思いますが、 なんせ暖かくなれば普通にギヤの入りは良くなるわけで。 今度冬が来た時にどうなっているか、ですね。 それまでは評価の仕様がありません。 追)4月購入で今12月です。 効果ありました。 5速にれる時にゆっくり入れないとギヤ鳴りしていたのがだんだん改善されていき、ついにギヤ鳴りしなくなりました。 他のギヤへの入りもどんどん改善されていきます。 寒くなってきて冷間時の1,2速への入りがややスムーズじゃなくなってきていますが、これは仕方ないかもです。 これを添加した車は普段あまり乗らない車なのでまだ1000㎞走行ほどですが、 1300㎞走行後には満足いく操作感のミッションが完成するのではないかと思えます。 心配なのはオイル交換した後にどうなるのかですね。
