Engine oil LIQUI MOLY or VALVOLINE

Been using Liqui-Moly 4200 5w30 and I don't lose/burn any oil (yet).

I too have a 2013 passat with the CKRA, I’m currently at 175k miles. I do my oil change every 7500 miles. I only use liqui-moly top tech 4200 5w-30. I usually never have to add oil between changes unless a lot of hard driving in the summer.

I have have had very good experience over the decades with Liqui Moly 5-40 and Total Quartz 9000 5-40 Both are excellent motor oils

I use 10W/60 Liqui-Moly with all my engines. I am old school and to a point, thicker is better.

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

Ughh. How did I miss that! I thought I was just saving $5 a liter for the same thing. I am so annoyed with myself. :banghead: I just pulled up the specs for both and indeed the Synthoil has a viscosity index of 171 vs 180 for the Leichtlauf. Also the NOACK for Synthoil is 12.9% vs 10.0% for Leichtlauf. From what I can tell the 12.9% NOACK of Synthoil is what doesn't allow it to have the VW 502 00 approval.
