Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2427

A great product from LiquiMoly, I used this in my 15 year old EA113 BWA engined Audi TT with 93000 miles on the clock, which had never been flushed before, but did have regularly oil changes. It seems to have quietened the engine, most notably, there seemed to be a slight dip in oil pressure to the turbo which would manifest itself as a minor whine when cornering at higher rpm - this has now been much improved, along with a switch to heavier 5W-40 Molygen oil. I had no problems with it, no leaks have occurred, it seems to burn less oil now and runs smoothly. Although mpg has not changed. I had no doubt the longevity of the effects of the flush will continue, as I keep up regular oil changes. This seems to be a “once every so often” flush, rather than an every oil change flush. Overall, this is a value for money product, that can help restore proper oil flow, especially to the top of the engine.

Excellent product. Tested on my 2020 Ford Puma 1.0T. Before testing, the engine sounded a little rough so figured an oil change might be due. Added to the existing oil and car left to idle for 15 minutes as per instructions. Once complete, oil drained and the waste oil was disgusting and had a petrol odour to it, very very dark too, so obviously a lot of deposits and carbon had been removed. Engine filled with LiquiMoly SpecialTec 5W20, designed for Ecoboost engines, new filter and left to run to temperature, engine noises and roughness has disappeared. Only time will tell if any long term benefits will appear but immediately, the engine sounds and runs much happier. Can honestly say it isn't snake oil, and effectively does it's job!

Ran it through a 2001 Yaris and it cleared the vvti out a treat.

Good very good for price and versatile tool and very durable too

Works as expected. Cleans deposits well before oil changes. Easy to use. Good quality, just a bit more expensive than cheaper options.

Great quality

I have given this ago on my 5 year Old Ford ST car. It seem to do a good job to clean oil from the engine. I would use this again 100% recommend this for older cars. You might need to do it couple of times.

It’s very soft to use and it’s durable,value for money

Good flush for my engine

منتج قوي جدا وفعال شكرآ لكم

Güzel ürün tavsiye ederim.

Absolutely love he Liquimoly products. I’m not much of an additives person, and I can’t quantitatively describe the benefits, but I’ve never used anything from them and the said “well, worse off now.” Ran the cleaner in a ford 7.3 diesel and greatly smoothed out cold idle and helped with cold starting.

Ich habe die Pro-Line Motorspülung direkt vor dem Ölwechsel verwendet und bin mit dem Ergebnis sehr zufrieden. Die Anwendung ist unkompliziert: Einfach zum warmen Motoröl geben, den Motor einige Minuten im Leerlauf laufen lassen und anschließend Öl und Filter wechseln. Schon nach dem Ölwechsel hatte ich das Gefühl, dass der Motor ruhiger läuft und sauberer hochdreht. Der Leerlauf wirkt gleichmäßiger und der Motor läuft insgesamt geschmeidiger. Natürlich sollte man keine Wunder erwarten, aber als Vorbereitung für einen Ölwechsel macht das Produkt einen sehr guten Eindruck. Besonders gefällt mir, dass die Motorspülung Ablagerungen schonend löst und laut Hersteller auch für moderne Benzin- und Dieselmotoren mit Turbo sowie Partikelfilter geeignet ist. Fazit: Für mich gehört die LIQUI MOLY Pro-Line Motorspülung inzwischen zu jedem Ölwechsel dazu. Ein hochwertiges Produkt, das einfach anzuwenden ist und den Motor optimal auf frisches Öl vorbereitet. Klare Kaufempfehlung! ⭐⭐⭐⭐⭐
