Tried using this with my B7 RS4. Didn't seem to help at all. Actually lost more oil in the first 1000 miles than normal...

I did seem to notice the engine running a little smoother and less oil consumption from what I recall, it has been a while since I used it.

Great product. I had my 2014 750 since 68k miles, and by 113k miles, oil consumption had gone up from a quart every 2500 mi, to every 1000 mi. Added 2 bottles (600mL) of Motor oil Saver. Drove 800 miles, then changed iil. It’s now been 2300 mi since that oil change, and engine oil level still reads full (100%). I’m extremely happy, and frankly surprised. Btw, I am using the same oil now as before, Mobil1 0W-40.

Every day will see new engine oil stains on my garage ground. It is a bad sign. Check out my 2001 E53 X5 3.0i BMW with 240k miles and found 2 most possible oil leak places. Rear main seal or oil pan gasket. Both of them will cost a lot. Be honest with you, I don't have that budget for it. However, I did have one bottle this Germany made Liqui Moly Oil Saver and gave a try on my oil BMW X5. Amazing , next day I found no new oil stain on garage ground. Looks like this 300ml liquid did the magic fix. This Germany made oil saver fluid costs like $12. Try it first if your BMW has similar engine oil leak issue. I truly believe it will not fix big major engine oil leak. But, why not try it ? what if it works ? Oh, yes, poor people like me still have right to own a BMW.

I put two bottles of the oil saver in place of the same volume of oil in my N51 powered 328 with 93k miles in hopes of resolving a small oil leak. While I couldn't tell if it reduced the leak I did notice that it somehow and unexpectedly was running with more power. I thought "placebo effect?" What I didn't know is that it is designed for INTERNAL leaks as well and it apparently took care of valve seal leaks I didn't know I had.

Had oil leaking out of my valve cover gasket right onto the exhaust. Figure I would give this a shot. Shocked, leak is resolved and my engine sounds more full now, suspect is assisted in valve stem seals as well. Awesome product.

I use the motor oil saver for my 91 MR2 Turbo. Quality product!

LiquiMoly products have never done me wrong so it couldn't hurt to use this additive every other oil service if your seals are old and want some extra piece of mind.

I had a few oil leaks and don't see them any more

I made the mistake only once to use the Audi recommended Castrol oil. Result: Castrol oil burned 4 quarts on 10,000 miles. Went back to Liqui Moly! Result: less than 1 quart per 10,000 miles! I did add this product and it's awesome!
