Engine oil Mannol or Motorex

As long as the oil meets the BMW longlife-04 specification it will be fine.

I use Mannol 5w30 premium which has BMW LL-04 on the back of the bottle.

I use Motorex semi-synthetic 4t in all of my KTM's over the years in a 15w50 weight. It has never been an issue. I have used Motul 5100 and 7100 in other bikes before, and I prefer the 7100 over the 5100. It feels like the bikes perform better when the temps rise and I'm really riding them hard.

Any oil that meets the manufacturer's specification for your car will be fine. Mannoil 5W30 fully synthetic meets VW 502.00 and ebay sell 5L for about £17 - why pay more?

Definitely better well known brands out there for cheaper prices. Look at Mannol oil. Mannol served me well.

I use Mannol. 5l of the stuff in 5w-35 retails at about £20 on eBay which is a damn good price.

I've always had good luck with manol oils.

Oi analysis came back and no extra signs of wear... Mannol is great oil just change at 5k and add in oil additive such as ceratec every other change

I've used for the last 20k miles and no problems! Just change at 5k.

Honestly Motorex is a good oil, but it is extremely expensive for what you get. I specialize in performing Used Oil Analysis (Worked for Reliability departments for mining outfits) and it’s just a Ho Hum oil.

Mannol is cheap for a reason as you never know what you will get in a bottle.
