Engine oil Mannol or ROWE

I use Mannol 7715 on my 3.0tdi

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

IIRC he told me that his dealership use Rowe engine oil for customer.

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

Well, I just bought some 5w-40 Rowe HighTec Synt RS oil to do an oil change on my 3.6 VR CC.
