Lubro-Moly Pro-Line Engine Flush (500 ML)

Worked good. Big fan of this company. Have use many of there products and has worked good. You can tell the difference after use. Used it with 130,000 miles on truck. You will not go wrong with using any of their stuff.

I tried this product because I have some varnish buildup on the head of my engine (as can be seen with the valve cover off). My engine has 315k and seems to have a little too much heat at the top end which cooks the oil a lot. I used this product and I expected more from the pictures on the Lubro-Moly site. It is stronger than the Pyroil or Johnssen flush I have tried, but I can't say it did any better than the Gunk or Berryman ones I tried. I haven't actually taken the valve covers off and looked, but it did look cleaner through the oil fill when the oil was drained. It did clean quite a bit internally and took out the crud that was built up in the rings as it said it would. Now my compression isn't so good as I depended on that crud to fix it. I am going to use it again for a while to see if it solves the problem.

Experienced home mechanic, 61 years old. Nothing better! Used on a sludged 2008 BMW X5 N52k 6 cylinder. Oil filter was filled with sludge so much freed up that oil filter "fins" were splayed open! Changed filter three times to get the engine clean. Lifter tick from oil starvation completely cured. 110,000 miles on vehicle. Instead of just idling with cleaner in engine, I held throttle at 1500 rpm for the 10 minutes. But that was my engine, my choice! Use a flush now on every annual oil change. I also highly recommend their Lubrimoly oil. Use in both of our BMWs for many years. Engines running Lubromoly oil STAY CLEAN. Very good price too. Try it once, you will notice the engine revs freer, and idle speed up slightly! That's impressive.

Decided to start changing my own oil on my E90, and this was in my fluids list alongside some MOS2 from the same manufacturer. I learned about this brand reading up on Porschesl and if its good for a Porsche its good enough for my BMW.I looked under my valve cover before and after and it did clean up some of the varnish. It wasn't a night and day difference, but you could tell it had cleaned it. This is actually good, as you can tell that it isn't harsh enough to start knocking debris loose in your engine, but strong enough to "gently" clean the insides of your engine.I followed the directions and drained and changed my oil immediately after. My oil was very fluid when it was draining and it was very, very dirty as opposed to its usual dark golden/dark brown tint. I believe this worked well, and I will use it on my next oil change to see if I get the same results.

I drained the oil and changed the filter on a Honda Civic with 67K miles on it. Then I put fresh oil and a new filter in and drove it 20 minutes to get it up to operating temperature - put a can of this in and let it idle 10 minutes. Changed the oil/filter again. The oil showed slight darkening- so it seems to have worked good. I have always used synthetic oil since the car was new- so I believed it was pretty clean inside (not sludged) but even so, this seemed to help. Liqui Moly has a good reputation- not snake oil like you might find at your local auto parts store.

Easy to apply. It does make my mpg gauge super sensitive to change. Almost an immediate reading and change in mpg reading and is showing less mpg by 1mpg which I guess good and bad in a sense. Idling and accleration smoother will update after 1 thousand miles. I have full synthetic 10k miles oil change.

I am always skeptical of products that offer magical solution. I tested this on my sluggish Acura 02 RSX and with about 110K miles. I did not change the spark plug or a tune-up. Previous oil change was at 100K. Following instruction I did an engine flush. The oil did look dark and dirty. Did a test drive and wonder of wonders it worked. It made a big difference and my "little bullet" is happily back to its old self.

My volvo S80 engine (~ 110k) definitely appreciated this product. Post flush and oil change it has been running smoother , quieter and better. I also put molly egine oil after the flush and am sure the conjunction of two quality products have been helpful .
