Engine oil Mannol or Motorex

Use an oil designed for a wet clutch, like this [motorex 15w50]

I use Mannol 7715 on my 3.0tdi

I use the mannol 5w30, it might be cheap but it's still just as slippy

Well I decided to try Motorex on my F800 GS, bought the 4T Top Speed full synthetic, in 15W50, boy I cant help it but recommend this oil, the gearbox is so smooth and silky.

Genuinely speaking, it's actually not bad oil at all. Apparently manufactured in Germany, meets or exceeds the OEM spec for my cars. In my 350Z which likes to drink oil, I change it using Fuchs Titan Race Pro S 5W-40 but I keep a bottle of this (also 5W-40) in the boot for top ups.

I run Mannol 5w30 for Japanese brands on my 202k km d16

Works fine but I might change to a slightly thicker one

I use motorex 30W in the air (or coil) side. The motorex is great stuff

Motorex 60:1 piston and rings go 180 hours with out issue, could go longer but i change it every winter, powervalve has yet to need to be seriously cleaned in 3 pistons.

I went with the motorex recommended oil. Worked great.
