Anyone using Liquid Moly's new green oil?
I'm about to do an oil and filter change, as well as most of the 120k mile B service and was collecting the parts...saw Liquid Moly's has a green oil that they tout as "new generation" and describe it as a Molecular Friction Control. Has anyone used this? Is it even authorized by MB? I know they can be strict with stuff like that. Any thoughts will be appreciated!
I’d personally still stick with Liqui Moly Leichtlauf High Tech and Ceratec. Molygen has been around for years, but I tend to prefer the more proven Euro-spec formulations for these engines rather than the “MFC/new generation” marketing angle.

Read my posts with pictures on how ceratec will destroy this engine. This is terrible advice. TERRIBLE. As a NEWB, welcome, but, you might want to hold back on commenting until you know the proper specs to advise. (original GDI oil spec is outdated and dangerous and DIRTY)
LM is a marketing gimmick. Use ONLY SP rated oils and NO additives. Ceratec will clog rings, increase blow-by and deposits on valves in this gdi engine.
OP, this oil is not SP rated...PASS
Find a 5/40 or 5/50 such as Motul, Amsoil, Castrol, Pennzoil, or Mobil1. Make sure to buy new stock and make sure the API seal on the bottle you receive says SP.

Interesting because I’ve run Ceratec in multiple vehicles over the years including my Defender, GLS, G63, R8 and GS400 with zero of the issues you’re describing. What I have noticed is smoother and quieter engine operation.Not saying everyone has to use it, but I haven’t personally seen the “engine destruction” claims play out in the real world. There are plenty of high-mileage Euro cars running it without issue.
I think the oil world is over analyzed. Run a high quality, more or less correct viscosity quality name brand full synthetic oil and change every 3-5k miles, and you are fine.
All modern full synth oils have more or less the right additive packages to last short oil change intervals and offer the same level of protection. I think most of the discussion is applicable for people who do 10k, 15k or even 20k change intervals.

whats the advantage of synthetic oil if you change it at the same interval as standard oil? Why pay the premium? That's the marketing ploy by the automotive industry IMO.

is the Liqui Moly that says "Leichtlauf" a ceratec oil? I can't find that term on the bottle nor the product description. I see that both the blue and green bottles of LM are MB 229.5 approved.

Both Liqui Moly options I'm looking at are MB 229.5 approved. So I'm confused as to why you say to avoid them. As a newb myself, I'm not familiar with "SP", "API", and "GDI"...I'll be looking that up soon with Gemini 😁
I use Mobil 1 0W-40 because it meets the MB spec for my engine and I can pick it up locally fairly cheap.
The Molygen New generation SAE 5W-40 pictured above appears to meet the MB 229.5 spec so I see no reason not to use it if thats what your engine uses. Try it out and see if you notice any difference.
For all fluids I look at the MB Bevo for the approval #'s. Then I will look around for the lowest price product I can easily get. I see no reason to spend more money on something that meets the same spec.
Follow the manufacturers recommendations for oil change intervals. The literature for Mobil 1 0W-40 FS European says Guaranteed to protect for 15,000 miles or 1 year, whichever comes first. But also says to follow the vehicle manufacturers recommendations in the Operators manual, which for my specific car says every 10,000 miles/1yr whichever comes first.
My Operators manual specifically mentions not using conventional oil. I dont even think you can find one with the MB approval on the bottle anyways.
The Liquid Moly website lets you choose which MB spec you are looking for and it shows which products they offer.
