Amazing product!

This reduced noise and vibration from a neglected rear-diff. Also, reduced additional friction in the diff case as the vehicle seems to move easier with less effort being that it’s 6 speed manual

I use LiquiMoly religiously for my engine oil. Gave this a shot for my GLK front and rear differentials. After one year (roughly 12k miles), I am going to change the fluid again and send the used fluid in for an oil sample. Will update when that time comes.

Replaced my original diff fluid on my n54 e60 at around 106k miles. Thanks FCP

Perfect for my 560's Limited-Slip Diff. Don't forget to change this on any car!

Bottle has a fill tube about a foot long that extends when you open it.

Got rid of I low wine I used to hear a 70 mph I still hear it at 40 but very low

Just changed out the rear differential fluid on my '11 E350 S212 which had 92,000 miles. The car feels smoother after the fluid change. I plan on changing it out when it reaches the 40-50k mark of usage taking advantage of the awesome lifetime warranty from FCP Euro.

This is a great product for my rear diff a3! Definitely recommended. The rear diff plugs for gen 4 Haldex are right next to the Haldex plugs. Literally a 10 min replacement. The bottle is fantastic and has a built-in plastic pipe. I still used a pump to inject the new fluid - was way easier!

love that the bottle has its own tube so you don't necessarily need a separate
