This is truely BRILLIANT at dislodging sludge and carbonised oil buildup throughout an engine. Perfect for imported European made cars that suffer these problems, as well as Aussie made V6 & V8 motors. Will help clean and fee up sticking valve hydraulic tappets. For best effect, remove and clean the sump pan after using this to fully remove sludge - simply draining the oil will not fully clean some pans due to internal baffles. Give the oil pick up strainer a clean as well. Don't be surprised if the amount of "crap" you get out makes you feel a bit sick but also amazed at this products cleaning ability.

I don't usually use an engine flush. Have been impressed by Liqui Moly's other products so I thought I would give this a try. This flush and an oil change quietened a quite noisy lifter and the associated engine vibration (the lifter would seem to be somewhat blocked and not fully pumped up). The previous oil change on its own did not have the same effect so I have to credit the results to this product.

I have used this product quite extensively and it has provided very good results where byI have had a Volvo v6 that went around the clock and the Engine was spotless inside and still going, I also have a magna with 400000 klms and the engine is perfect like it came out of the show room.I highly recommend the product.

After not changing the oil in my 100 series Landcruiser for almost 100,000km I knew there was plenty of build up and a few noisy lifters. I flushed with this stuff exactly as directed on the bottle and then drained the oil. After re-filling with new oil and changing the filter, the car just seemed much smoother and the lifter noise at start up was gone. I'll try not to be so lazy between oil changes, but I also might give it another flush before I do an oil change going forward.
I read so many reviews about this product. I was still not confident to use it, but tried it and i'm amazed how effective it was. I used different way to finish after the flush.• Added engine flush in and ran the engine for 15 minutes.• Took the dirty oil out and lot of sludge came out• Then I added cheap semi synthetic oil and ran the engine on idle for 15 minutes again• Took the oil out again and kept it for future use if I engine flush again.• The clean cheap oil I added became black within 15 minutes as it mixed all the leftover deposits of engine flush and sludge that was left after the first drain.• Changed the filter• Then added full synthetic oilNow the new engine oil is so clean, it’s really hard to see the oil level on the gauge.
I change my oil and filter religiously every 5,000kms, using the same products: MANN filter, Castrol Edge 5W-30, Liqui Moly Oil Flush Plus & LiquiMoly MoS2+ additive.Liqui Moly Oil Flush Plus completely cleans the engine internally, removing all sludge, deposits and old dirty oil, getting it ready for new oil. I’ve done this on my cars since day dot, and over 150,000kms later, the engine is still clean, buttery smooth and efficient as the day I bought it.
Incredible product. I flush my engines every 100k, keeps the engine performing more efficiently and better fuel economy. The pick up is instantly noticeable.You can see once you add the flush and drain the oil that it takes a lot longer than usual.
was always skeptical about these products, how ever they are safe and use as instructed, basically add more cleaning properties too the engine oil ( engine oil already has these cleaning propoerties but in lower amounts). i use this every second or third oil change deping on used oil colour
Initially I was bit hesitant to buy this as it was bit expensive compare to other engine flush! But to my surprise this has shown its magic in every aspect! My 2012 Xtrail diesel has got a complete new life! No unnecessary noise, more power, ready pickup u name it! Just try it, it wont disappoint you! Its worth every penny!!
This is an extremely effective and well engineered product from a trusted brand, I used it in my engine and immediately noticed how well it cleaned out the carbon build up, I no longer have hard or rough starts and the engine no longer hesitates at slow speeds, the performance has increased undeniably. For the price, I don't think you can get a better product to give an engine a new lease on life. I will be using this at every oil change interval from now on. Ensure to follow instructions carefully!
