Engine oil Mobil or OEM Audi

I use Mobil 1 because it's the only oil that prevents VVt noise in my NB Miata

I've only used Mobil 1 5w-30 Full synthetic. I think it's the only oil I would ever use. This Mobil 1 oil has simply been the one that I used from the get go, mainly due to recommendations, and it does what it needs to do. I feel confident using the product.

The Toyota mechanic who has a YouTube channel (Car Care Nut) has previously said that Toyota OEM oil is Mobil 1 (with a few exceptions for collaboration cars).

Mobil1 15w-50 (red label) was always good to me, and readily available at wally world. Never had lifter tick in my S50US, on track or otherwise, and it went to 298k before the head gasket gave up. Absolutely could have resealed the engine and ran it another 100k+ (swapped an S54 instead).

I use M1 Extended HM with an stp premium filter. Go about 10-13k between changes.

I mostly use the 0W-40 full synthetic Mobil 1 "European" or w/e they call it. I change my oil every 5K miles, including filter (Mann).

I personally use full synthetic Mobile 1 usually.

mobile 1 is a good brand. id go with it

Why not just buy the Mobil 1 and take it to the dealer?

My 1.8T has just over 103k miles. I got it at 78k, and until about the 95k mile mark, I've been using M1 0W-40, then switched to M1 5w-40 Truck and Turbo-diesel, since I wanted peace of mind with its extra additives and protection. I figured since this oil is meant for high operating temps and high load in turbo-diesel engines, it would be just as good in my daily-driven and weekend-tracked 1.8T. I change my oil a few days before going to beat on it over the weekend, otherwise I'll change it every 3k to 5k miles. Also, I have had some valve noise (tapping of some sort), the whole time I've had the car. I'm guessing it's lifter noise. I'm not sure, but I was told to try a heavier weight to counteract it, hence the switch to the only decent 5W-40 sold on base. Still no difference in noise.
