    • Powerful flush — pulled out serious grime at 132k miles
Size: 500 mL
I used the Liqui Moly Pro-Line Engine Flush on my 2013 Ford F-150 3.5L EcoBoost sitting right around 132,000 miles, and it definitely did its job. I recently tightened up my maintenance intervals to change the oil every 3,500 miles, but I wanted to give the engine a proper reset. Following the bottle instructions, I added the 500 ml can to the warm engine oil, let it idle for about 10–15 minutes without driving or revving it, and drained it immediately. Even with shorter change intervals, the oil that drained out was pitch black and smelled heavily of spent contaminants and built-up gunk. The EcoBoost engines are notoriously hard on oil with direct injection and twin turbos, so seeing that much suspended carbon and residue come out was proof enough that the detergents were doing the heavy lifting. Refilled with fresh synthetic oil and a new filter, and the truck is running smooth and quiet. Given how well it cleared out old buildup, I plan on adding this to my routine roughly every 3rd oil change (around every 10k miles) to keep the turbo oil passages and variable valve timing components clean. Highly recommended for higher-mileage turbo engines. ... show more

    • Product worked very well and really cleaned the engine oil system.
Size: 500 mL
Boy did this product work and clean out the junk in my engine. I followed the instructions on the can. When I drained the oil it was as black as I've ever seen any engine oil. I do believe that it may have cleaned things a little too well. We had not been having any oil consumption issues prior to the cleaning. Post cleaning we seem to have a little bit of an oil consumption issue. I'm thinking that maybe there is still some residual cleaner left in the system and after a couple of oil changes we'll be back to 'normal'. ... show more

    • Great for cleaning the engine before changing oil
Size: 500 mL
Have used a lot of Liquimoly chemicals, always good quality and consistent performance. I am a repeat user. I have used the engine flush on a Mercedes diesel, Alfa Romeo turbo 4, and two BMW's. I did an oil change without the flush at 5k miles on the oil. The next change I used the engine flush, also at 5k miles on the oil, and there was a significant difference in what the engine flush cleaned out. ... show more

    • Tips and tricks
Size: 500 mL
I watched several videos by professionals who used this. Follow instructions. Make sure the engine is warm before you put it in. Make sure you have everything you need. The biggest tip I got that was repeatedly emphasized by the pros was to buy a “cheap” oil in addition to the new oil. After you run the flush drain the oil and flush. Put the cheap oil in and “rinse” the inside of the engine with the cheap oil. Then drain again. Replace the oil and filter with your good stuff. I followed these instructions or suggestions and…. I sat in the truck while the flush was running. It’s a 13 year old truck with 150,000 miles. It was running strong but burning oil and kind of loud. Sounded like it was growling. There were some ticking type noises that made me nervous. As I sat in the truck and let the flush cycle through the engine at idle I could literally hear the flush working. Very slowly it was like someone gave the engine a Xanax and you could hear it getting quieter and calming down. I drained, rinsed with cheap oil only letting the cheap oil run through at idle for another 15 minutes then drained again. The oil flush was clearly important. It didn’t come out as black as the first drain but it looked like old nasty oil. The truck is no longer burning oil. My gas mileage has increased significantly and it is running so quiet and smooth it’s unbelievable. I used a little less of the liquid Molly flush than it called for regarding the flush to oil ratio. I didn’t want to do something too intense to the inside of the engine. But the results were remarkable. Just as advertised after following the instructions. I also added the liquid Molly oil additive to the final oil change to ‘lube’ the inside of the engine. I plan to do another flush in about 10,000 miles. All that to say, yes, you won’t be disappointed as long as you follow instructions and a few tips and tricks. My truck is almost running like a brand new truck and again it’s an old and tired truck. I will use this as part of a high mileage maintenance and perform the flush every 50,000 miles or so. I feel confident it will extend the life of my engine based on the results ... show more

    • Great Option Before an Oil Change for Turbocharged Engines
Size: 500 mL
I purchased the Liqui Moly Pro-Line Engine Flush because I was a little overdue for my oil change and wanted to clean out any deposits before putting in fresh oil. One of the main reasons I chose this product was that several online sources indicated it is safe for turbocharged engines, which was important for my vehicle. The process was simple—just add it to the old oil, let the engine idle as directed, and then perform the oil change. I can’t physically see what it cleaned inside the engine, but it gave me peace of mind knowing I was starting with a cleaner system before adding new oil. The engine seemed to run a little smoother afterward, although that could also be from the fresh oil. Overall, if you’re looking for a reputable engine flush from a trusted brand and want something suitable for turbo applications, this is a product worth considering before your next oil change. ... show more
