Never heard of this claim, not even from liquimoly. I used to use their same oil in the picture, Toptec 5W-40 on my Skoda Superb for years in 2015
I highly recommend running Liqui-Moly. Amazing oil and I have run it in every german car I have owned with no issues.
I also use liquimoly 4200 top tech in my 2022 rs3
Oil needs to be specificly designed for VW. I use [LiquiMoly Top Tech 6200 VW 508 Spec](https://www.fcpeuro.com/products/vw-0w20-synthetic-oil-change-kit-liqui-moly-mann-538720?ads_cmpid=21759816943&ads_adid=170798399249&ads_matchtype=&ads_network=g&ads_creative=715097223081&utm_term=&ads_targetid=pla-293946777986&utm_campaign=&utm_source=adwords&utm_medium=ppc&ttv=2&gad_source=1&gad_campaignid=21759816943&gclid=CjwKCAiAt8bIBhBpEiwAzH1w6Xei8JrrLq8MziCPaWxXnDYi7k66dFtY4Tj6tiqXtBQJa-l1PzNhoBoCp0QQAvD_BwE).
An oil change to Liqui Moly 5w40 worked wonders for mine. Still zero lifter tick after about 1500 miles. Highly recommend.
Liqui Moly Top Tec 4200. I buy it from FCP and return my used oil in the same container and get 100% of my money refunded through their lifetime warranty program.
On the recommendation of my mechanic in reply to my quest to eliminate hot lifter tick in my 89K 1.6, Liqui Moly 5w40. Hot lifter tick is still nonexistent 1500 miles in.
Liqui Moly Molygen 5w40. Not cheap but I swear by it, made the engine quieter too
So if you review the virgin oil analysis database, it includes idemitsu 0w-20 and 5w-30 and for both, the TBN is rather weak in comparison to other more readily available blends, also, the viscosity at 9.5 cSt for a 30w, some 20w come close to that. Does any of that matter? Not a whole lot, but it shows that there's nothing special about the oil. Generally speaking, higher TBN is better.
It’s not any better than Walmart Castrol, just double if not triple the price. I’m 160k tuned!!!
