Engine oil LIQUI MOLY or Castrol

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

Liqui Moly all day. Now that i’m over 200k in my Touareg i’ve been getting the light green containers which makes any oil leaks detectable with a black light. Not that i’ve had any but i think it makes it easier for my tech if ever the situation arose. As for filters Mahle, Mann, and Hengst are the go-to’s.

I'm doing mine a little more frequently now at 280,000km. I do every 7,500km with liquimoly molygen.

5w40 is fine for the summer.. I would go with liqui moly next time if the prices are similar.

(2013 VW GTI) Used to use this exact oil and noticed LiquiMoly 5W-40 (they even have a UV dye version if you have any sneaky oil leaks) performed better for my car specifically. I do frequent changes 3000-4000 miles and the oil doesn’t seem so burnt, I experienced less oil consumption, and the engine oil temp seems to sit slightly lower as well.

For those who aren't certain about which oil to use, I've read that the "fully synthetic" oil in the USA really isn't fully synthetic and the Liquid Moly stuff from ECS tuning might be a notch or two better than the Mobile 1 from WalMart*.
