Unreal. It works it has actually helped the heads and evrything else rear main all of that, yes hey leak but don’t pour a quart in 2k anymore that’s for sure, unbelievable the can has such a distasteful name like your a butthead trying to add snake oil to fix leaks, this stuff should be called engine seal rejuvenate, you can add too Much which would cause swelling and failures but a can a year big difference, unreal difference car is not puking anything it even cold starts happier(full bolt on crank 600 e55) it’s like a new lease on life, maybe from the power levels it’s capping just a few leaky stems but it’s a big difference non the less it works(600miles on new 7.5quart Castrol, mso2 and seal rejuvenator) car rips.

This stuff is amazing. If you own an older Porsche like I do, leaking oil is a fact of life. I was about to change the oil return tubes on my 39 yr old 911 due to continuous (slow) dripping of oil. I have always heeded manufacturers recommendations about not using fuel or oil additives, but I ignored myself and figured I would give this a try, since the leaks seemed to be coming from the tube seals, and not the tube itself. I used 2 cans since the 911 takes 13 quarts of oil. Ran it for a few hundred miles. The leaks diminished, but did not disappear. I then changed the oil and used 2 new cans of the Motor Oil Saver and again ran for a few hundred miles. I currently have NO OIL LEAKING from the return tubes. This product worked as advertised, and I would highly recommend it.

I was having a terrible leak from the N52 valve cover gasket and the seal in the oil filter housing gasket. I used the motor oil saver to specifically address these two issues until the seals were replaced but the leaks continued. I don't think this product is meant to seal such leaks.

I bought a 2011 N63 x5 50i to use for my Youtube channel and it was in shambles, after 150 miles driving from the dealership it lost enough oil to show up on the oil level screen. When I got home 1300 miles later, I flushed the engine 4x over the course of 1 week. Then finally settled on last oil change and added one and a half bottles of this, and one and a half of ceratec and it's been 6K miles and ZERO oil consumption, ZERO smoke. So yeah... I would say this works. Most problems and legends about engine flaws are due to owners who don't do jack squat in terms of maintenance... ie: they believe BMW service interval recommendations...which is a crock of poo. Change your oil every 4k miles and you won't need to worry about all these crispy seals leaking oil and consumption. I have changed the oil and not added this stuff after the initial 6k and there is still ZERO consumption.

Not sure how well this stuff works but it gives me good peace of mind

Great!

Didn't completely eliminate what I consider to be higher than normal oil consumption in my 2011 LCI E70 X5 N63 4.4L, but the blue smoke was significantly reduced after only a few hundred km. Have re-ordered the product for continued use in my next oil change.

fixed a lot of the oil consumption on my m54b30

Fall of 2019 I purchased my brother's 2011 MB C300 4Matic Sport. It had covered only 48,000 miles in its 9 years. When I got the car, they had not driven it more than 200 miles in the prior 10 months. The first six of those months they weren't even in the state. Anyway, not long after I got the car, I noticed the occassional quick puff ofoil smoke at start-up. This car is not only my '2nd car', but at times it only saw only moving in and out of the garage for days at a time. Start-up smoke indicates valve seals. I did some checking and saw others praising Motor Oil Saver, so I gave it a try. It has been in the car for 45 days, about 600 miles. The third day after adding I did see a puff. I haven't seen anything since. NOTHING. Not when driven off-and-on normal distances. Not when it only sees in and out of the garage for a few days. I am beyond thrilled and beyhond impressed. This coming weeked I'll likely do an oil change, and will be adding Liqui Moly's 'CERATEC' additive. I will probably look at swapping to Liqui Moly products anywhere possible. Thank you! no
