Engine oil Mobil or OEM Audi

I’m team mobil 1, 160k and going strong.

Mobil 1 5w30 and oem Subaru filter. I change mine pretty religiously at 3750 miles. I know it might be overkill but I’d rather be safe than sorry and if my engine blows up I will for sure know it wasn’t my fault for neglecting maintenance.

I tested it myself on my 3.0T, pumped everything out with the extractor, then jacked the car up and pulled the plug, catching evening that drained out in a measuring cup. It had less than 1/4 cup of oil left in the pan.

Extractor all the way. As for The amount left behind, it is inconsequential if you are maintaining a short oil change interval. I've seen a couple YouTube videos showing maybe 3 or 4 oz left behind.

Did this every oil change on my sq5. Made it 180k miles before trading it in. Works very well. That was the easiest oil change I’ve ever done. Of the 15 minutes the job takes, about 4 of those minutes is actually doing something

Anything Dexos2, my fiancé worked at a chev dealer and I was getting their bulk 5w30 dexos2 at cost and my LSPI issues went away, mobil1 ESP went in last oil change at 250k km

Definitely prefer the extractor here! So easy/clean and gets all of the oil. At least in a Q8 and b9 A4/5 it got everything

I’ve done both and extractor takes out like 97% of oil. I still had about a half cup when I pulled the plug.

I found Mobil 1 0W-40 to allow a lot more timing chain and lifter noise, especially at startup but even after, then switched to Castrol Edge 5W-40 and the noise suddenly wasn't there. I've used it ever since.

I just go to crappy Grease Monkey and do full synthetic Mobil 1 for like $100.00. Then I drive home, and double check their work.
