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

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!

About 80K on my 2011 BMW 328i convertible. I was getting the typical valve cover oil leak: smoking from the engine compartment and burning oil smell (from dripping onto exhaust) upon starting in the morning, and intermittently while driving. Added the Liqui Moly Oil Saver and drove normally. After about 3 weeks and over 500 miles it did not seem to be doing much for the oil leakage, but the car ran more smoothly and I noticed the oil temperature (by the dashboard gauge) was running lower than before. Then after a subsequent 250 mile round trip the leakage stopped completely. No more seepage, oil fumes, or burning smell. I was really surprised, as I was expecting to have to replace the valve cover gasket and possibly the entire valve cover which is an expensive job. My advice is to be patient with this; it does work, but you need to give it time. As stated it took about 800 miles to work for me. I would recommend taking a fairly long highway trip if possible after a bit because that seemed to make the difference in my car.

Great product, engine works smooth and less noisy on w221 Mercedes Benz.

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.

Good product

Unlike most people with old turbo Subarus with over 200K, my original engine has perfect leakdown, meaning that there's no cracks in the piston rings or anything along those lines causing oil consumption. Given 15 years and 210K miles, it's no surprise my valve seals aren't "like new" anymore. I was going through a quart of oil every 1K miles or so, even more when idling a lot or starting the car many times per day.Had my oil changed about a week ago. I've driven, as of writing this, about 180 miles. I went to check my oil level yesterday (I typically had to put just a little oil in every week, or about 1 QT every 1K miles) and the oil level, even with thinner 5W-30 oil (I top off with Shell Rotella 5W-40), the car had not lost any oil. I do know my oil pan was leaking a decent amount - probably not enough to make a substantial difference on the dipstick, but it was nonetheless - and I haven't gotten time to put the car up on a lift and see if it solved the oil pan leak. I do know that my car doesn't smoke when I stomp on the throttle and there isn't any smoke at startup anymore. Liqui Moly suggests that it'll take around 300 miles to get the full effect of the stuff, but I've gotten the full effect already!Definitely recommend for the cheap price.
