I'm curious to know how many of you actually use this stuff, and what is your impressions of it. My X5M is going in for an oil change on Wednesday, and I'm changing my current oil from Mobil 1 0W-40 to Liqui Moly 5W-40, to see if that helps mitigate the oil consumption issue.
I also bought a can of Liqui Moly MOS2 Additive, that I wanted to try first. I've heard a lot about LM Ceratec, but wanted to get some opinions. I've seen videos on Youtube testing this stuff, and their findings are neither positive or negative, so is this stuff just snake oil.
And if things go well, I will also introduce my AMG to it. So, before I pay $60+ for 2 cans, I wanted to hear your stories first.

What nobody has used this stuff?

I'd also be curious as I always see this suggested when I'm buying parts from FCP Euro etc.

Although I can say switching to the 5w should help a lot. I hate 0w oil, the only reason manufacturers use it is because of fuel mileage. A cold engine as it sits has the highest tolerances between the pistons and block, the largest gap to allow for heat up expansion. And you have an oil that is the consistency of water when it's cold. Of course some of it gets through and burns off.

I used to work at a Subaru shop and when they switched to 0w20 and longer oil change intervals (solely for mileage and a reported lower maintenance cost) they were replacing engine blocks at 30-50k miles because people were unknowingly running them out of oil...

Too thin an oil isn't good for a engine either. As oil serves three purposes; Cleaning, Cooling and Lubrication.
I just wanted to hear, someone's perspective on LM Ceratec. The good and the bad. I am dropping in a can of their MOS2 additive, that has some of the same ingredients as Ceratec.
I figured 10oz of the stuff won't kill me, mixed with 9.5 quarts of oil.

I use it {5-40} to race and on the street all the time but use the Bizol 0-40 on the street now to keep the pump quiet.
I can tell you my engine looks perfect inside, perfect bores, perfect bearings after some very hard driving /
racing. Well......I did just break a piston but not oil related. LOL

I used ceratec in my Cayenne turbo and recently I’ve started to used it in the wife’s GL550. The first week the engine felt so smooth, but then you get used to it and don’t feel special anymore. It definitely working. And you’ll only need two bottles for every 60k miles. The Porsche crowd believed the ceratec help eleminate the bore scoring problems. I like it and I used it in my vehicles.

I’m on my second oil change using Ceratec, I’ll be honest I don’t notice much. I use Amsoil 0-40w signature series/ceratec I find my oil pump is louder then usual. My car howls down the street until it warms up and quiets down (still is there just much less noticeable). I wouldn’t say it’s worth the $60 premium to run it, but on most other platforms it performs well from what I have read (and that’s why I continue to use it). It’s just warming up in my area so I’m interested to see what spring/summer fuel economy looks like, I would guess probably unchanged or within margin of error. In the end I’ll probably just start using the Mo2, since it’s much cheaper and probably is 80% as good as the ceratec

Interested as well to hear what others have to say. I bought into the FCP lifetime warranty and bought myself a 5w-40 kit with MoS2. Going to be trying this stuff out next oil change.

hachiroku

I've used it...I do feel a difference but the difference felt is much smaller than MoS2. They are different products so I cycle through Ceratec once a year or once every 2-3 oil changes. The issue with BMW's besides they're build to fall apart is that they purposely build their motors to fail after the warranty period ends. This also is why they tend to change up their oil specification for their M cars once they've had more than a handful fail before the warranty period ends. For the older M cars they've recommended 10w-60 as these engines were failing within their warranty periods causing BMW Corporate to cover the cost of the engine replacement.

If you are in fact burning oil, I would look into a heavier weight if it is safe which it most likely is if you life in a warm enough climate.

Yuille36

A thicker weight oil isn't the way to go either, as it's harder to pass thru the tight tolerances of the engine, and the rod bearings.
Besides the oil pump has to work harder to push the oil thru. And the thick oil is like molasses when it's cold out.

This was Liqui Moly response to my email.

Dear William,

thank you very much for contacting us and your interest in our LIQUI MOLY products.

According to our database BMW requires a motor oil with BMW LL-01 FE performance in either SAE 0W-30 or SAE 5W-30 viscosity for use in yor S63T engine. The use of a non- LL-01FE approved motor oil in another viscosity is not recommended.

For your X5 M our Special Tec B FE SAE 5W-30 is our recommended oil, it has the necessary LL-01 FE factory approval and is ideally suited for the use in your S63T engine.
To avoid excessive wear even under heavy use and to further improve the performance of your X5 we also recommend you the following products:

Use our Pro-Line Engine Flush at the next oil change. It will remove dirt, sludge, carbon etc. from the inside of the engine which will help the new oil to perform as best as possible from the beginning on. Further it will also remove carbon build up at the piston ring groves which will allow the rings to float freely and raise compression. A very effective way to extend the life of any engine, to optimize the oil consumption and to improve performance. For preventive maintenance we recommend using Pro-Line Engine Flush at every 2nd - 3rd oil change.
Add Cera Tec to the fresh motor oil to further increase wear protection and reduce friction. Cera Tec is a combination of a chemical surface protection and a solid lubricant. It is our latest high-tech additive formulation for less friction and wear in the engine. It has proven itself worldwide even under extreme conditions in races and will protect your engine even under tough operating conditions. The ideal dosage of Cera Tec is at around 6-7% of the total motor oil volume.


To maintain the sensitive fuel system of your engine we recommend you to use our DIJectron as preventive fuel treatment regulary every around 2400 miles. DIJectron is a unique combination of state-of-the-art LIQUI MOLY additives, developed in order to keep clean and protect the fuel system of modern, direct fuel injected (GDI) engines. Using DIJectron will significantly reduce the risk of having an LSPI event caused by deposits at the injectors and inside the combustion chamber.

I tried both Ceratec & MOS 2 several times in my ML63.
Ceratec didn't do much, same noise level, vibration, and consumption.
However, with MOS 2 I felt the engine operating smoother. MOS 2 coated everything when removing the valve covers, even the oil cap had MOS2.
Moreover, the oil temperature sensor is reporting cooler oil temps by up to 7-8 c on average, which might be due to the MOS sticking/ covering the oil temperature sensor and giving false readings.

However all of these findings are subjective and the correct way to go is to conduct an oil analysis and check for wear material.

Yuille36

This is exactly, what a wanted to hear from previous user of this product. Thank you.

DrugDealr

Us Mustang guys develop a tick after the first oil change, ceratec seems to make it go away. That’s my experience with it.

feeshta

I took that plunge a few weeks back and did the package deal from FCP that includes the 5-40, Ceratec, Oil saver(I have a slight leak from the rear main seal), and cleanout. Ran the cleanout formula through the engine for 15 minutes before the oil change as called for, then did the oil change and added Ceratec and oil saver and set the fill level precisely with the hidden menu.

I can't tell you to what percentage the oil itself (I previously ran Mobil 1 0-40), the cleanout, or the Ceratec made the difference, but the engine is definitely more happy after doing so. Particularly when it comes to smoothness at high revs and willingness to rev, there is a quite noticeable difference. Enough so that I ordered a second kit for my 2007 Cayman S which I just got notice is at the post office for pickup this afternoon.

Yuille36

I just put in a can of Liqui Moly Jetron Fuel additive to clean my injectors, and a can of their MOS2 Oil additive.
I drove the car 50 miles this morning and haven't noticed anything different.
I'm just not convinced on Ceratec just yet. But hearing everyone's stories is swaying me a bit.

hachiroku

as far as Ceratec...i maybe felt 1-5% smoothness increase...MoS2...15-25% each time. they serve different purposes as Ceratec supposedly fills pores within the metal surface to aid with increasing the height of the boundary layer of oil film.

if you were looking for a miracle additive, Ceratec is not that.

Yuille36

Not looking for any miracles here. Just trying to mitigate oil consumption on my X5M.

hachiroku

oil weight has a direct relation to oil consumption. when vehicle owners state x brand of x weight and x brand with same weight does not burn is not the same as each brand's oil has a different actual viscosity. if i run 0w-40 mobil on my E63 my engine consumes oil. when i run 5w-40 mobil my engine does not consume oil. let us know how the switch to 5w-40 liquimoly works out for you long term as for me switching to the thicker weight oil solved my consumption issues with my M156.

Yuille36

My E63 doesn’t consume oil, but my X5M does. And that is the issue that I’m trying to find a solution for. I’m hoping that switching from Mobil 1 0W-40 to Liqui Moly 5W-40 with MOS2 will help mitigate my oil consumption issue.

Saurabh914

Really? Mine still consumes oil even after switching to 0w-40. Weird

Yuille36

My E63 will prompt me for a quart of oil, when I'm very near to my next oil service. Only then has it ever needed a quart of oil.
Now my X5M on the other hand, was asking for oil every three to four months. I think that it has more to do with the turbos consuming oil, and possibly leaking valve seals and maybe some blow by at high revs.
I do get on it from time to time. I went up to NJ for my Mom's Birthday a few months ago, and I had my foot in it the whole way up and back. Then about a week later, add a quart of oil.

hachiroku

my buddy's tire shop neighbor bought a X5M for his wife a few years back. loved the car...but the oil consumption was a constant battle with the dealership. the dealership before has replaced the turbo sets 2 times due to oil seal failures etc, and then agreed to rebuild the motor of the X5M due to extensive oil consumption. they did this 3 months prior to his warranty ending....he was happy...then the motor blew up 2 months after that warranty ended...out of warranty. with a fight with BMW of America and the dealership on selling of a lemon which in actuality is "by design" and a couple of lawyers, BMW of America offered to sell him a new X5M for a huge discount. his wife is now driving a new X5M. i haven't checked in with them to determine how the new one is, but he swears to NEVER EVER buy a BMW ever again. BMW's are disposable and built to fail around warranty time. there is a reason why their lease's are so affordable, because they want to keep owners leasing new vehicles while sticking it to the owners who attempt to own their vehicles past warranties. the plastics they use fail and fail hard. as much as AMG's also use plastic within the engine bay, I've yet to have a failure of plastics at 160k. maybe the previous owner has, but I haven't in my 80k of ownership.

moving to a 5w-40 for the X5M should help. let us know in a month how the oil is doing.

Yuille36

Will do, and my X5M is past it warranty period. The only money, I've spent thus far has been on preventative maintenance and services.
I hate hearing horror stories, with AMG's or M's. But the X5M is an phenomenal vehicle, and I just love it along with my E63.

I use Ceratec in combination with Liqui Moly 0w-40.
Really makes the Engine idle much smoother. No Oil consumption or heat issues
