Engine oil Castrol or OEM Audi

Using Castrol EDGE Euro 5W-40 after watching a EN owner on YouTube suggested it. Car runs great in this 110 plus days in Texas

I did 100k on Castrol gtx in an f4i plus tens of thousands on other bikes using the same oil. I buy it in bulk and it goes in the whole fleet.

In the rare occasions I get it from there, I use Castrol or Mobil One 5W-30 or 40.

Walmart carries jugs of Castrol Edge SPT 0w40 A3/B4 for much less than quarts at AutoZone

Run it in my R, wife's GTI, and even ran it in a WRX I used to have. It's good oil, the analyses I've sent in over the years don't lie!

Castrol Edge 5W-30 for me. I live in Vegas where it barely gets under 30 degrees in winter even so it's a better oil for the hot climate in live in

Fa20 DIT..Castrol edge Euro..0w 40 winter, 5w40 the rest..111k miles, stock block, E85, 400ish whp, drive like I stole it..I change it every 3k, 4k a few times in a pinch...I also run an IAG street AOS

5w-30 Castrol LongLife in mine in Europe. But often interchangeable, but always depending on what the manual says. Top thing though I’ve found after 120k miles in on a TSI is: keep it near top of dipstick to bypass chain and turbo issues (turbo especially relies on good oil supply). Listen for rattling chain and listen to turbo note, can often hear changes and usually due to lower oil level.

I had a 2009 VW Rabbit, and I'd often buy Castrol Syntec (full synthetic). I haven't seen this 'Euro Car' formula, but it says it's full synthetic, so I think it would be fine.

Regardless, I haven't heard of Aral, but I wouldn't knock it without proof that's worse than Castrol.

Mine eats Castrol Syntec 5w40 like it's going out of style as well.
