LIQUI MOLY Motor 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.

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 a pretty decent leak im thinking coming from the head gasket (ignition coil gasket) or oil housing in my 2012 mercedes c250. This def slowed the leak to buy me time to make the necessary repairs. The can let's you know it makes old o rings, seals "maluable" so they stop leaks. If those seals are really bad though this could possibly deteriorate them quicker. Just my opinion. It's a bandaid for an oil leak most definitely.

I used this to help seal a small leak on a 2011 BMW 328 E90. the leak was for a oil pan gasket. so far after 5,000 miles it stopped the leak! very impressed.

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.

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!

Works as described, saved my engine from leaking oils
