Ceratec or MoS2
Hi all,
I did +- 5.000km ago an oil service with an engine flush first and then Liqui moly 5w40 + 2 bottles Ceratec. Good combination, engine runs fine and smooth. For the next oil service I should only add 2 bottles MoS2, no more ceratec right? Or is it better to stay at ceratec also for the next change?
I found also this: Ceretec bonds to parts and is good for 30k miles/50k kms so you run it, then change the oil and don't put it back in for the next 3 or 4 oil changes, most people run MOS2 in those oil changes instead.
What do you recommend guys, just need some advice, because I will change my oil over a few weeks.

The additives bond to parts that you want them to bond to, but also to parts that you don't want them to bond to.
They bond to the oil rings and in time much reduce the oil scraping function, causing puffs of oil smoke and in time oil smell in the exhaust.
They bond to valve seals and that can go both ways.
They bond to calibrated bores and holes, reducing passage size.
They bond to filtration elements inside the filter, reducing oil filter life, you have to account for this.
I don't even want to think about what they do inside an oil cooler.
So stop being so over enthusiastic about adding more and more additives.
Remember how the manual specifically says not to add any additives ?
Yes, the engine will sound smoother and friction areas get additional protection. But the process is not without downsides.

Ceratec is used 1 time a year to treat your engine or 30k miles or 50k kilometers. MoS2 should not be used during the same oil change interval. Your next oil change after Ceratec treatment would then be of only MoS2...once you reach 30k miles or 50k kilometers, you'll want to cycle Ceratec again if that is the intent.

Anyone any experience? I did already the oil change 5000km ago with ceratec + liqui moly. Now I want to do again the oil service, but still dont know to add just the liqui moly oil or also Mos2?

Molygen is the one premixed...The oil is bright green...and is recommended to be used in conjunction with ceratec or mos2 as mentioned it already has the anti friction additives in the oil.

- Ceratec treatment @ 33.5K miles with Liqui Moly 5W40 Leichtlauf
- Going to run a moderately longer and one-time 6.5K mile OCI to give the product a bit more room to work in.
- 5K mile OCIs after that with Liqui Moly 5W40 Leichtlauf and MoS2 (probably at every oil change).

Step 2 Kit - https://www.fcpeuro.com/products/8-c...i-moly-lmk0006
The only part I skipped was the engine flush. Picked up the car with <32K miles and a detailed service history so I wasn't worried about needing to "flush" anything.

I've been using Pro-Ma MBL8 for over a decade in all of my cars. I started using it when I had that ticking lifter noise in the past (in one of my old cars) and no other product comes close to it.
Curious to know why you use this product in your c63? Have you got a bit of a noisy motor?

Found this from FCP Euro on Liquy Moly additives
https://blog.fcpeuro.com/liqui-moly-..._hsmi=85132180
He talks about using Ceratec and MoS2 @ 5.50 minutes.

As a follow-up, I did the Ceratec with Leichtlauf @ 33.5K miles but did not run it that long. After further research, I landed on 3K mile OCIs for the M156.
Currently running Motul Xcess Gen2 5W-40 without any additives. Will assess a UOA or two and then take it from there.

Here's my strategy for the SL:

You asked for more opinions.
No, ceratec and others wonīt stack up and restrict oilpassages.
But, i have an another opinion also about those additives, they arenīt designed for making camshafts life prolongued.(akillesheal of m156)
Zinc and Phosphorous is, in short ZDDP.
Half a bottle Red line break in additive is a good start.
And no,, it will not destroy your cats if someone says so.
If running two bottles in our engines(as recommended blend when running in our engines) you might hurt them, but it takes a lot of miles to do so still.
