Engine oil Mobil or OEM BMW

My oil report on 0w30 mobil1 esp looked good. I'll keep using it. Mix of track and daily duty.

Seeing good results, lower heating, smoother functioning with Mobil Super Moto 15W-50 Synthetic Technology Engine Oil.

I was riding in the Himalayas where low-gear, high-acceleration could not be avoided and decided to try this. Noticed better performance, lower heating and decisively moved away from RE's semi-synthetic.

I wouldn't limit yourself to VW brand oil only if another "approved" oil is cheaper. VW has a document listing which oils meet their spec. I use the MOBIL 1 Esp x2 (it's on the list) since the 5 quart bottles are usually cheap from Walmart.com.

I’ve ran mobil1 5w30 for a few years now with oem filter on my 1990

I use 10w40 also from Mobil 1 high mileage. A lot of our engines will have a tick on start up or once hot, if so with your Motul, switch brands to another top tier on next oil change and see if your engine likes that brand more.

I changed oil with 80% Mobil 1 high mileage and 20% Lucas high mileage oil stabilizer in it, did better than just Mobil 1 high mileage 5w20 alone in summer, (very hot temperature).

M1 ESP is arguably the best oil out there. It does not shear fast, doesnt degrade with 5% fuel dilution.

I run Mobil in all my cars. The regular 0W-40 is cheap and easy to get, as is the 5W-30 ESP for the RS3. Right from Walmart.

I've been running Mobil ESP 0w20 (VW508) since my 1st oil change at 3k miles (5 months into ownership), then another oil change at 7600 miles 10 months later. I've ran a few Auto-X events, a light educational track day (not pushing the car too much), and certainly am otherwise not shy with the throttle at all. I have also had 1k miles on my stage 1 tune since July.

You should stop using Mobil 1 oil period. Their oil is dog shit when it comes to wear protection, cold flow, burn point, and more.
