Engine oil LIQUI MOLY or Mannol

Only vw507 that I can get in my area is motul or liquimoly. I get whichever is on sale.

I’ve been using top tech 4200 for years in my CKRA passat and swear by it. No issues at all currently at 175k miles

Used to go with Mobil 1 ESP for my Passat, but after discovering idParts.com, I now only run Liqui Moly as it was cheaper for me to buy an oil change kit on their website than it was to run to my auto parts store

Liqui Moly is good.

I only use liqui moly toptec 4200 in my 12 Jetta tdi

The 5w30 or 0w30 is perfectly fine. Since I live in the US Midwest I’m going to start just running 0w30 liqui moly year round

I use liqui moly Toptec 4100 because in India, spec for 2.0 TDI is 5W40 and we do not have DPF so VW505 oil is recommended which Toptec 4100 conforms to .

Decided it would be a good idea to change oil to Liqui Moly since the car is trying to be kept going for another 10 or more years . Main dealer was their standard 0W-30 , but i am going to 5W-30 top tech 4200 . Cars manual said its fine spec and originally had 5W-30 day one .

I use it in my wife’s Fiat 500 and my mk7 Golf GTD(service every 5k miles). no issues at all.

LiquiMoly is a line of many products, some are API/ILSAC oils for American and Japanese cars, some are ACEA/Euro oil spec oils. In general they are decent products if you are buying the top end of their line.
