LIQUI MOLY Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2037

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.

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

My 06 Altima (185k miles) had been burning massive amounts of oil (like 4 quarts every 800 miles) due to a leaking PCV valve hose that took forever for me to narrow down (months). So after getting that under control I figured I needed to decontaminate the poor engine. When using this I idled my car to operating temp (about 8 minutes). Poured the bottle in, idled it for another 15 minutes. Drained the oil (black and thick). Put the plug back in, poured about 2.5qts of new oil in. Idled it for 10 minutes. Drained that (black but much thinner). Took the old filter off. Let both areas drain for 10 minutes. Put the plug back in, put the new filter on and filled with the 4.6qts of new oil my car calls for. Ran for a few minutes (like 2 with a few revs) and then let sit for 10 mins before checking the level. When I checked my dipstick it was so clean I thought I had a leak because I couldn't see it on any of the crosshatch. I ended up having to go by touch to get the reading. This stuff is amazing.

Seemed to really clean up the oil and the motor

After 20k miles on bike....worked pretty good removing oil bag gunk. Like giving my bike an enema .....used a small scope camera in oil tank and did work pretty good. Didn't capture before n after though.

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.

Good quality and fast delivery

Excelente producto

¿Es parte indispensable en un cambio de aceite? No, la verdad no. Sin embargo, la fórmula cumple perfectamente con su función si sigues las instrucciones al pie de la letra. Si no sabes cómo usarlo, búscalo en YouTube (preferentemente en los canales oficiales de la marca). Entonces ¿para qué usarlo si no es indispensable?, bueno la respuesta es sencilla: para sacarle el mejor provecho al aceite nuevo habiendo limpiado por dentro el motor. Si quieres que el aceite nuevo realmente cumpla con su propósito (lubricante, detergente, etc., etc., etc.,) lo ideal es que "trabaje" en un máquina lo más limpia posible. Así que, en conclusión, es un excelente "pre" para que el motor esté en mejores condiciones para recibir el aceite nuevo.

It’s perfect it can make the engine brand new from inside I used it with BG 44k

This works great. I used it after I had just done an engine flush and oil change. Turned my fresh oil black! My truck has had the engine changed, has under 130,000 on the engine, and has been regularly serviçed with full synthetic oil etc. Not an old negleted beater. Check engine light is on from an oxygen sensor, because I ran seafoam through it when I did the first oil change. Code is cleared now, has not returned. Just before my last oil change in my 2008 Sierra 1500, with the 4.8, I added some transmission fluid to my oil (old school teick to clean engine out, I have been doing this for years) idled about 5 km, then added some store bought engine flush. Idled for 5 minutes, then drained all the oil. I jacked up my truck and let it fully drain for about 20 minutes until no oil was left. It came out black, and my oil filter was heavy I then filled it with cheap conventional oil and put a new filter on. My oil pressure went up slightly, and the lifter tick went away. I drove it for 2 days, putting less then 200 km on the new oil. It was still clean, and as clear as the day I put it in. I added this engine flush, and idled it for 15 minutes. The oil pressure went down slightly, and the lifter tick returned. This stuff cleaned a ton of crap out of my already flushed engine! Oil filter was again heavy, even after draining the oil from it for 10 minutes (not as heavy as the first one, but still, heavier then a used filter normally is) Drained all oil out again, refilled and put a new filter on. As you can see from the pictures, the oil came out black again. The oil pressure went up higher then it ever has been since I owned the truck, and the lifter tick is completely gone. Definitely reccomend this. Also, if you are at a point of doing an engine flush, I would probably do what I did and use this as a second flush, as I believe it works better then cheap store brand. How could it get the oil that black if the store brand stuff did it's job? I really did not expect my oil to be as dirty as it was

It's good product
