Engine oil LIQUI MOLY or Shell

I use liquimoly leichtlauf 5w-40. Bit of advice: these are VERY easy to overfill if you're not careful, so refill slowly. Put in less than you think you need, once it registers on the oil level sensor, then start the car for a minute. After that, leave if for a few hours to drain before continuing to fill.

amazon.ca has Liqui moly TOP TEC 6200 SAE0W-20, VW508 00/509 00. Been using this since day 1 on my 2021 Tiguan with no issue.

I live in a dusty climate I change my oil at least annually and I use Mobil one in my Volvo, Kirkland synthetic in the kids cars, and rotella in my air cooled vw.

I buy Liqui Moly 6200 from germanparts.ca for about $70/5L. Our Tiguan consumes a lot of oil sadly, so I buy a lot of it. My mechanic recently recommended using Liquid Moly 2331 (Leichtlauf) 5W40 to see if it helps with oil consumption, and have had that in for the last month or so.

I use Rotella T6 5W40 on my stock motor STI.

Liqui Moly 0W-20 LR for my F-Type-R. Doesn't use much oil, so cost is somewhat irrelevant.

Had an E63 that I recently traded with almost 200K miles, a few months ago I scoped my 1 and 5 cylinders and they had what I would consider normal to no wear. So as a DIY'r, here are my observations, This is a bigger issue in the States than it is in Europe. ... Keeping the engine clean is key. Frequent oil changes no more than 5k mi, using quality oil and fleece filters, formerly a Mobil 1 guy, now using LiquiMoly.

now im using shell long ride currently at 1500km and i havent feel any vibration yet and its cheaper than amsoil.

Whatever weight the owner's manual says it takes, I'd use that. You'll definitely want to go with a high quality oil though. I personally use Liqui-moly... I have 192,000 on my 2012 A6, and she's still purring right along, a lot of which in my opinion has to do with the higher end oil.

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*.
