Engine oil Mobil or OEM Audi

Mobil 1 Turbo Diesel Truck 5W-40 in an ALH since new. 10K OCI, engine with 280K running like new.

Mobil 1 ESP 5W40

Mobil1 is great oil and what I personally use.

One of my cars has 240,000 miles and burns 1/2 a quart in 10,000 miles using Mobile 1 5W-20

10W-40 full synthetic Mobil 1 fixed that on my 05 Rio with the B6 Mazda engine. The sound goes away shortly after an oil change and it stays away for about 2 or 3,000 mi until the oil breaks down and it starts to make the noise again.

Mobil 1 ESp is excellent , just changed mine few days ago

Mobil Super 3000 XE 5W30, hat die Dexos2 und kostet online regelmäßig unter 30€ für 5l. Lief bei mir mit dem gleichen Motor jahrelang im Astra.

I've been having my Hybrid oil changes done around 12k ODO miles (~6k ICE miles). Mobil 1 Hybrid full synthetic oil. Blackstone says very little oil contamination at all and additives all still in great shape. In comments, they say I can go longer.

New Audi do not have the oil sticks to check the oil levels, so they always under pour the engin oil in the car, my q8 is been serviced by Audi and past 2 years I have to top up oil (which is free as car is under warranty) but last month I got pissed and asked them to top it up to max and car runs much smoother and fuel consumption for 1 full tank is 130 km better.

I only really noticed issues with oil consumption when I use mobil1, so I try to avoid that.
