Engine flush
I did use this to flush out the sludge for d in the engine of my car. It is an excellent product which removes the sludge and dirt formed due to burning of oil inside engine. After using this with the new oil my car is functioning very well. Worth using whenever we change engine oil. Keeps engine healthy 👍👍👌👌

i used this liqui moly 2037 Pro-line in my Hyundai Elantra CRDi 2004 model. its give excellent results. Before this i used several flushes but not upto the mark. This is the first time i used in my car. There is a lot of difference in several aspects. Only the price is little bit higher, rest no remarks. thank u amazon for providing such brand.

It's a pro!
Well anybody who knows about the liqui moly products knows that the proline is their top ranking products from the brand and is very effective compared to normal engine flush. Watch youtube reviews from USA, you will understand the greatness of the product.

I used this on a 2002 BMW E46 I had purchased with no idea of the prior maintenance history. Engine was running a little rough, especially on cold starts despite an oil change immediately after I purchased the car. I elected to use this product for a thorough engine flush which I performed as follows: I poured in the entire contents of the can into the crankcase with the old oil, and ran for about 12 minutes at idle speeds (anywhere between 10-15 minutes is safe). I drained the old oil which as expected, was pitch black. I then refilled the engine with cheaper oil I had purchased from Ace (around 140 AED for 7L) with a brand new filter. Ran that oil for a day just to clean out any remaining deposits and solvent (even though it is designed to evaporate). Some may ridicule this as overkill, but honestly spending 160 AED for a cheap oil and filter is a minuscule price to pay for engine longevity and peace of mind. I drained the oil which had already turned a dark brown, exhibiting just how much of the old oil and deposits remained in the engine. I filled it for the the 2nd and final time with Liqui Moly's "Molygen" 5w40 which is BMW LL-01 certified. After almost 2 weeks, I've inspected the oil several times and it has remained remarkably clean despite driving almost 1,000km. The engine settles down much quicker, and is certainly much quieter and smoother before. If you are religious about changing your oil every 5,000 to 7,000km and have maintained your car since new, this product and entire process is unnecessary. Regular oil changes and the additives/detergents in modern motor oil is sufficient. However if like me, you have purchased a car with no idea of the prior history of maintenance (which you should determine from actual service records and not just the hearsay of the seller) then this is a worthwhile extra step for peace of mind.

¿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.

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.

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
