I would have to believe that the levels of MoS2 already in oil would be minimal. Additional benefit would come from the use of dosing the engine with a can.
That's pretty much it; you're coating most of the metal inside the engine with Moly (especially after the second application) instead of just having a little to provide a little less friction.

All overpriced snake oil bullshit.
Change your oil regularly, keep it topped up, and your engine will out last your car.
No need for additive supplements ever

Yea, hmm I'm not sure I'm going to be drawing conclusions on MoS2 based on a guy who ran it in his single cylinder push lawn mower for 15 minutes versus in my 3 liter BMW engine for 5000 miles. Interesting YouTube channel though, thanks.

Not I.
I'll just keep wasting my money on my R1150 RT, f10 535Xi, M Coupe, E39 530i and my Toyota Tundra.....

Charging out here with a broad-sweeping generalization and your "smoking gun" is a Project Farm video?

You have a lot to learn on the subject.

Maybe you have stuck piston rings? Keep
us posted on the long term results.
After the CCV didn't make much of a difference, my guess was piston rings too. It's been two weeks and the oil level has not dropped. Normally, I would have added a quart by now. I definitely will update this post based upon my results.

If the Liqui Moly Leichtlauf oil works, I'll be doing the same to my daughter's VW Passat. It seems to drink oil as well, and I suspect it suffers from the same piston ring issues as the M54.

I read this thread https://forum.e46fanatics.com/showthread.php?t=1271909 a few months ago and decided to follow Don Fields' (MrMCar) recommendation to use Liqui Moly Leichtlauf 5W-40. I had been using AMSOIL European 5W-40 with their engine flush at each oil change for many years.

My 2002 330i has over 245,000 miles on her, and she was using a quart of oil every 500 miles. I replaced the entire CCV system, OFH gasket, all vacuum lines, and everything in the vicinity with all BMW parts a year ago at 235,000 miles. The oil consumption didn't change.

For the Leichtlauf oil change last weekend, I used 1 1/2 cans of the Liqui Moly Pro-Line Engine Flush prior as instructed. So far, I am happy to report my oil consumption is way down - like 75% less than before.

I also changed the transmission (5-speed manual) and differential oils using Red Line MTL and Royal Purple Max Gear 75W-90 along with the Liqui Moly Anti-Friction Additive for Manual Transmissions & Differentials in both the transmission and differential. I have to say, the diff is much quieter now - no more whine.

We'll see what the long-term verdict is on Liqui Moly products, but so far, it appears to work well.

I ordered the engine flush, I got 2 bottles. I'm doing my oil pan gasket in a week or so and I plan on using the flush and then filling with LM 5w30 and Cera-Tec. I live in Vermont so 40 weight is not really an option. The oil pan gasket is leaking moderately but not profusely. Oil consumption is not that extreme actually but I do know that prior to my last oil change about 5000 miles ago, the car went at least 15k miles without an oil change. I did a vanos rebuild and valve cover gasket 3 months ago and there was a decent amount of lacquer inside the vanos and its pistons. There is also some ticking noise which I'm actually starting to suspect might be from my AC compressor but can't say for sure. When I drain my oil before the oil pan job I think I will drain a little, take a picture, then add the engine flush, run the engine for the specified 15 minutes and drain the rest of the oil and compare. I'll post it on here, as long as I remember to do it lol.

I should say it's not recommended. Winter is 6 months long and it's cold.
You'd be fine if you did. I don't remember Vermont getting THAT cold, although 6 months of it would wear on my mood I'm sure!

Oil Consumption Update

Two weeks and 1,364 miles after using 1.5 cans of Liqui Moly Pro-Line Engine Flush and switching to Liqui Moly Leichtlauf 5W40 oil, I have not added any oil or other products to the engine. The oil mark on the dipstick is down maybe 1/8 inch from the center of the "full" marker.

This is amazing as I would have added 1 to 1.5 quarts of AMSOIL to top of the engine by now. (I had been using AMSOIL European 5W40 for many years.) The Liqui Moly engine flush and Leichtlauf oil really seem to work wonders with the stuck piston rings.

I'll post another update when I reach 3,000 miles on the Liqui Moly oil.

I think your results will remain favorable. I’ve had consistent success with that engine flush on 3 engines. BMW’s N55 and M54 and Mercedes’ M272. I stayed with my M1 0w-40 however, my favorite oil.
