Is Using Liqui Moly Ceratec Safe?

I would stick with the Leichtlauf as it's on the 229.5/229.3 list whereas the new Molygen stuff hasn't made it onto the list (even though it specifies that it's 229.5 compatible on the bottle). Oil changes aren't as easy as on regular W204 since you need to also drain the oil cooler up front. The oil cooler and lines will have about a 500ml capacity out of the 8.5L fill spec. I found the vacuum out the dipstick method did NOT work with the M156, it'll only collect about 6L

Motul 8100 5w-40 with LiquiMoly MoS2. If you're in a very very cold climate and need a 0w...some have said the 0W isn't as good as the 5W as far as composition for Motul 8100. I'm no expert, but 5W works for my climate.

Im about to try the Ceratec... 2 bottles for a fresh oil change correct? I will probably revert back to MoS2 for subsequent oil changes.

Those "what oil and whatnots to use on my M156" never cease to teach me something else. I'm that "go for the owner's manual" kind of guy. I live in a tropical country, with climate varying between 20°C (68°F) to 35°C (95°F). I'm still using the Mobil 1 0w40 as it's recommended by the manual. I've heard and read several other opinions regarding going to a 5w40 or a 10w40 (mostly from Motul, we don't have Liqui Moly in Brazil). Is it still safe to stick to OEM? Do we have any other better options considering the Mobil 1 0w40 is already a recommendation from 7yr ago? How much Ceratec you suggest in that case?

So didn't see this answered, sorry if I missed it: But is it a prerequisite to run Ceratec FIRST before switching to MOS2 at the next oil change or can I run MOS2 right out of the gate? The analogy I'm thinking of is it's like maintenance for ceramic paint coatings: You have to get the correction (engine flush) and then the ceramic coating (Ceratec) FIRST, and then do your maintenance/recharge (MOS2) once a year for it to work... Or is it more like creatine, where you can pre-load (Ceratec) if you want, but it's not really needed and you'll eventually hit your stores eventually with the normal dosage (MOS2) after a while?
Just did service B and my indy shop used M1 0W40 so I bought some MOS2 based on other threads I read where it seemed like folks were recommended either Ceratec or MOS2, but I see here it looks like Ceratec first THEN MOS2... No?
TIA

they can be run through the engine in any order as long as not at the same time. in the perfect world...Ceratec first if a brand new car/engine, but per LiquiMoly, after MoS2 should not be a concern.

Cool, thanks man.
So I assume my shop left the oil level in the middle when they changed it (I will confirm the exact level), so can I just add (2) 300ml bottles of Ceratec and still be under the FULL mark? And if I'm at the full mark, with an extra 1/2qt be bad?

generally speaking you don't want to go over the full line. if you're at the half mark adding 2 bottles i believe you should be fine. i have a w211 with updated dip stick part number and i'm always over the full line now at 9.2-9.5 quarts.
if you did a few full throttle runs you'll burn some oil which could bring your oil level down if needed.

See this thread. BK44K is supposed to clean like magic.

about 1500 KM in after my first ceratec dose. No ticking and car running like a beast. Highly recommended.

Bit of background first;
I've noticed in hotter weather here in Australia when ever its above 35c (96f) I get the dreaded lifter tick. It can even be heard from within the car especially on acceleration.
It got to the point where it got so frustrating, I took it to my local indy. We tried both 0W40 or 5W40 with no real noticeable difference, especially when its that hot outside. Where I live it can get to 46 - 48c (120f). So a week later, my mechanic put 2x bottles of Liqui Moly Ceratec in the motor with fresh Liqui Moly 5W40 oil. Over night the lifter tick has basically disappeared! Ive had this stuff in the car for about ~4weeks now, and the only time I hear the lifter noise is in the morning if I haven't started the car for a few days. Even then, its only for 30secs before it just goes away.
So my question as per the subject... Is Using Liqui Moly Ceratec Safe in our cars?

There are 2 possible reasons you hear the ticking.
1. There is dirt in the valve, that prevent the valve from closing.
2. There is dirt in the inlet that prevents the oil from getting into the valve.
In both cases the dirt need to be removed, and that is best done by the following product, also from Liqui Moly.
Product # 1009
This product do dissolve impurities all over the inside of the engine, including oil feed to the Hydro lifters. It has a proven record, and is safe to use.
This can be run together with Ceratec, witch is totally safe to use. I have done more than 100K miles on my E320 with that stuff in the oil.

Flat tappet engines are notoriously noisy and perform best with a high moly oil. That’s all there is to it.

Just did an oil change( I use 8100 and molygen) and just put 8100 back in.
The car is noisier and the rattle is more noticeable now and I swear the oil temps are about 5c higher on average.

Sorry, not many video's in English, about the Liqui Moly hydro valve lifter treatment.
Found this.
It can't repair bad valve lifters but it can help reduce tapping noises.

Just add MoS2, man... was hard to see that thick grey stuff being poured into the motor. Crazy its safe, looks like it's going to clog the filter.

The Hydro lifters, do get charged by oil pressure. There is a valve in the top of them, that should prevent the oil from disapering, once oilpressure is gone. ( engine off ).
