Engine oil LIQUI MOLY or MOTUL

That said, I use Motul 0W20 in the winter and 5W30 in the summer.

Random guy who works on these cars here, change it at 5-6k regularly. Ignore the casuals here who don’t work on these cars, and especially Ignore the factory recommended interval. Your engine will last much longer, you’ll reduce wear on the timing chain, turbo, as well as other components. You’ll also reduce the chance of your piston rings getting glued together with carbon creating excessive oil consumption. Just change it. I recommend liquimoly oil.

5k or less with Liquimoly. Just had oil pan and upper timing cover replaced at 123k miles (plastic parts leak/ fail bc of heat cycles) and my timing chain looked like new, and not one spec of metal or debris on the bottom end. Unitronic stage 1+ since 75k miles.

I send an oil sample to Blackstone Labs every single time I change the oil or the dealer changes the oil. As part of that analysis, I pay the few extra bucks for a TBN calculation. On my SQ5 and S3, after running a fill for 10k to 12k, those TBN values always come back greater than 1.0 indicating that there’s still enough remaining additives to continue running that fill for even more miles still.

My local shop in Canada does it for $125 plus tax and uses liqui moly oil.

I just run Motul. 7100/7200 or the 300v.

Years ago I went down the oil rabbit hole and now I recommend motul 7100 4T

Liqui moly is the best stuff in the market! I have been running it in my ST for years. It runs better and has lower oil temps than motorcraft.

Now if you were to get Motul 300V, there would be a real difference there. Higher end “boutique” oils have additives, such as esters that will build up a film on moving parts over time, adding a layer of protection if for some reason you were to lose oiling to that part.

Motul 8100 x-clean 5W40 seems to be the sweet spot, all of my friends drive it in EA113/EA888 engines.
