Liqui MolyMotor Oil Saver | 300 ml | Oil additive | SKU: 2020

I used this on my Subaru Forester with 95,000 miles. It wasn’t burning a ton of oil before, but there was a small leak and some gradual loss over time. After using this product, everything stopped — no more drips, no noticeable oil loss between changes.Honestly, I couldn't be happier with the results. It’s a quick, affordable fix that actually works. I’m planning to use it on my other high-mileage cars as well. Definitely worth trying before going down the repair route.

Works as described, saved my engine from leaking oils

Stopped my oil pan leak! I used this for my 2007 BMW 328xi E90 N52. My oil pan had been leaking and so was my oil filter housing. After using 2 bottles, my leaks stopped and still hasn’t leaked after I used the Liqui Moly Engine Flush. I combined this with the Mos2 Antifriction engine additive. My car is running great!

Excellent Product.

I have an Audi A4 b8.5 that was leaking a lot of oil needing an oil change after just 1500 miles. It was subtle at first to where you wouldn't notice, but over time it started leaking puddles of oil 7-8 inches in diameter. So when I checked underneath the car, I noticed that it was leaking where the oil pan gasket is. Then I remembered my mechanic friend telling me about this Liqui Moly stuff and how he uses it on oil changes for cars that have high mileage with worn out seals. I took his advice bought some and used it when I did my oil change. I did 4.6 QTS of 05-30w Valvoline HM oil with a mixture of LM Oil Saver. Drove it around for about 30 miles, and overnight I noticed the puddle was now smaller around 3-4 inches instead of the 7-8 inches in diameter it usually is. The oil leak remained that way for a couple of weeks, it lessened but didn't stop it completely, it was still consistently leaking oil 3-4 inches in diameter. However once I hit the 700 mile mark, boy I was surprised, the leaks have lessened significantly to the point where my garage was mostly dry now. To this day it is holding oil quite nicely.I definitely recommend this to someone looking for a temporary fix, but just know it takes 500 miles or even more according to my mechanic friend for the seal to take full effect.

I have a 2004 BMW 325xi with about 130,000 miles, purchased a few years ago with 106,000 miles. It had a bad oil leak from the time I bought the car, losing about 1 quart every 500 miles or so. I believe the leak was primarily the front engine seal, but the oil pan gasket may have also been contributing. Hard to tell because even after cleaning the underside of the engine, after driving a bit the oil would blow around and cover the oil pan. Last oil change I used one container of the Motor Oil Saver, and I've used almost no oil in over 3000 miles. I believe most of the little bit I did lose (about 1/4 of a quart) was lost as the product was still reconditioning the seals and gaskets. After the last trips totaling 500 miles, there has been no oil loss whatsoever. I was skeptical of this product's claims, but I'm happy to have been proven wrong!

First I'll preface this by saying that I'm starting the rating of this at 3 stars not because I don't like it, but because I feel it's a good baseline. I am going to update this review over the course of the next few weeks until I do or don't see what I think is the end result after operating my Jeep for the suggested amount of time by Liqui Moly's instructions. I've used a couple other Liqui Moly products in the past like their gas additives and valve cleaners all with decent results. So trying this Engine Oil Saver to possibly save me a hefty repair bill in the short term seems like a no brainer. I have a 2013 Jeep Grand Cherokee 3.6L with around 140k on it. It is a very well cared for jeep and always garaged. In the last week or so I've been smelling some burning oil and a little smoke coming off the exhaust manifold into the cabin which of course stinks. It has not allowed me to run my heater and fans so time for a fix. Took it to my mechanic and he's pretty sure the valve cover gasket is leaking on to it causing the smoke. There is also a possible oil cooler leak inside (common Jeep GC problem) which brings up the repairs cost significantly. I also have had a very slow leak around the front engine seal next to the alternator for a while now. I'm not concerned about that one but hoping this stuff might just bandaid that too. Both of my known leaks seem very slow and do not make it to the garage floor, yet. While no mechanic is going to recommend an additive like Liqui Moly for obvious reasons, I told him I may try it as a temporary solution until I got some money together for a proper repair. I went ahead and asked if it would damage anything. He quickly said, no, and admitted to using similar products on his vehicles in the past between repairs. So that brings me to yesterday. I had just recently changed my oil so aside from having to drain out a little to use this Liqui Moly Engine Oil Saver, it's as easy as just pouring it in. I topped off my oil afterwords to right in the middle of the "safe" zone on the dipstick and immediately went for a drive for roughly 1 hour. That's all the time I had and did not expect miraculous early results but checked under the hood right when I got back. Still smoking but no surprise there. Liqui Moly recommends at least a couple hundred miles to see results. For my leak being the valve cover gasket which is right at the top of where oil circulates, I expect it will take time to get up there and work itself into the gasket if its going to work at all. This review will be updated about every 100 miles of driving which for me is about once per. Bottom line is, if you plan on keeping your leaky vehicle and can afford a proper repair, just get it done asap. I feel regardless of the results with this Engine Oil Saver it is never intended as a permanent solution. When money is tight, and when isn't it, these products are potentially a good stop gap. Guess I'll find out!

2013 BMW 328i xDrive. Recently had my engine replaced with a 65k N20 replacement from a 2016 X3. Started leaking oil pretty bad after a few thousand miles of use. I used one can of oil saver and it decreased after 700 miles or so. Second can of oil saver completely stopped leaks. (Undercarriage is dry now at about 8000 miles) and engine runs smoother with Lq Mly Ceratec.
