Engine oil LIQUI MOLY or Shell

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 .

R60, I use liqui moly 5w-40. 0w-40 is good too. Flows better at start up. Same viscosity at operating temp.

The most notable change between the Gen1 and Gen 2 is viscosity. It is much thinner than old oil. few of my customers have already noticed higher oil consumption compared to old formulation. Liqui Moly has done the same. They have reformulated their popular Leichtlauf 5W40 to much lower viscosity. @ 100C it is almost as thin as 5W30.
