Engine oil LIQUI MOLY or OEM Audi

Ich kauf immer Liqui Moly, deutsche Herstellung, da hab ich mehr Vertrauen.

Ich nehme nur liquid molly oder Castrol, man hört so viel, früher wäre es egal aber inzwischen sind die Motoren und der Kettenantrieb bzw die Riemen viel billiger/ empfindlicher gebaut, da würde ich kein Risiko eingehen wollen.

Mk7.5 GTI 2019, bought new and ran 0W-20 for the first couple years for warranty (approx 70k) and then switched to Liqui Moly Top Tech 4200 / 5W-30.

I'm curently at 134k and no issues, I'm switching to the leichtlauf 5w-40 on my next service for the extra protection and because I can get it a few dollars cheaper than the Top Tech 4200.

Moly is 100000% better than whatever the fuck they use at the dealer. I swear, the moment I decided to start taking my VW to an indie shop that works on exclusively German cars, and asked them to use LiquiMoly, my car has run significantly better.

I run liqui moly 4100. I run 5w40 because I want something a bit thicker than what the manual calls for.

Liqui Moly Toptec 4100 5W-40 works if you feel like you need something thicker, but these diesels don't run crazy hot like gas + turbo engines.

I use top tec 4200 5w30 but I change it every years and I’m not driving much.

New Audi do not have the oil sticks to check the oil levels, so they always under pour the engin oil in the car, my q8 is been serviced by Audi and past 2 years I have to top up oil (which is free as car is under warranty) but last month I got pissed and asked them to top it up to max and car runs much smoother and fuel consumption for 1 full tank is 130 km better.

My 2013 GTI I believe has been running off of 5w-40 since I bought it. Supplied a shop with European 5w-40 and it still ran fine. Now it's winter, 6-12F outside and I just got the oil changed at a local drive and shine to 5W30 full synthetic and the GTI is running like garbage! RPMs are staggering all over when it goes into neutral, instead of 750RPMS it likes 1k to be normal. It just overall feels wrong.
