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!

Used it in a BMW N55, The engine was smoother and bit more responsive. Engine start up too is bit quiter . Its premium quality oil additive and suited for premium car engines. Most of all I think the additive works in the background secretly protecting you engine and giving it a long life.

Used to flush out the oil on our R56 mini before refilling. It seems to have worked very well as we're back to struggling to read the level of clean oil on an impossible to read R56 dipstick. Now having to rest the dipstick on kitchen towel again to see how far up the damp oil is sitting! The old oil was pretty black even though it was within service limits, but it's now back to clear, even after a short run. The Mini dipstick is a pain to read, I have no idea why anyone reinvents the wheel, as a flat dipstick works the best.

I added this product to the old oil right before the oil change and let the engine run at idle for about 10 minutes. The drained oil came out much darker and thinner, showing that the deposits inside had been dissolved. During the process the engine ran smoothly with no noise or fluctuations, and after adding the new oil it felt quieter and more stable. One 500 ml can treats up to 5 liters of oil, and it works with both petrol and diesel engines which is very practical. The only important point to note is that the oil and filter must be changed immediately after the flush.

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

Very good product. I recommend the seller. Fast delivery, everything as described. 100% satisfaction.

🔎 This flush engine product comes in a small bottle. Needs to be poured into your engine( like a regular oil ) before the planned oil change. 🧡 It was my first time using engine flush product( recommended by a friend ). I poured it into the engine and let it run, as recommended on the bottle. When removing oil, it was more smooth, and I hope cleaned the engine better, than just changing the oil. It is easy to use, effective and I would recommend using it. 💲 A good value for money product.

Kurzfazit Ich habe die Pro-Line Motorspülung von Liqui Moly vor einem regulären Ölwechsel eingesetzt und bin mit dem Ergebnis sehr zufrieden. Die Anwendung ist einfach, die Wirkung sichtbar und der Motorlauf danach spürbar angenehmer. Anwendung & Handhabung Die Nutzung war unkompliziert. Ich habe die Motorspülung bei warmem Motor dem alten Öl zugegeben, den Motor etwa 10 Minuten im Leerlauf laufen lassen und anschließend wie gewohnt das Öl gewechselt. Die Anleitung ist klar verständlich, sodass keine Unsicherheiten entstehen – für die Anwendung ist kein Spezialwerkzeug erforderlich (der Ölwechsel an sich bleibt hier unbeachtet). Wirkung & meine Erfahrung Beim Ablassen des Öls war sofort erkennbar, dass die Motorspülung ihre Arbeit gemacht hat. Das Altöl war deutlich dunkler und gefühlt schmutziger als sonst. Nach dem Ölwechsel lief der Motor subjektiv empfunden ruhiger, besonders im Kaltstart wirkte er gleichmäßiger und leiser. Ich hatte zudem das Gefühl, dass der Motor spontaner auf Gasbefehle reagiert – kein dramatischer Unterschied, aber doch wahrnehmbar. Qualität Ich nutze Produkte von Liqui Moly schon länger und auch hier macht die Pro-Line-Serie einen sehr hochwertigen Eindruck. Mir gefällt, dass das Produkt explizit für Werkstattqualität steht und laut Hersteller keine Dichtungen oder Lager angreift. Fazit Für mich ist die Liqui Moly Pro-Line Motorspülung eine sinnvolle Ergänzung vor dem Ölwechsel. Sie kostet nicht viel, bringt aber mess- und spürbare Vorteile. Ich werde sie definitiv wieder verwenden – besonders bei Fahrzeugen mit höherer Laufleistung oder längeren Wartungsintervallen.

Esta marca alemana es garantía de calidad. Uso este limpiador de motor antes de cada cambio de aceite de motor. El proceso es muy sencillo: echarlo directamente en el cárter del motor (tapón de llenado de aceite) y arrancar el motor. Lo ideal es echarlo una vez que el motor esté a temperatura de servicio. Este punto permite que la temperatura del motor ayude al detergente que lleva el producto a eliminar las impurezas y depósitos del interior del cárter ocasionados por el propio desgaste del aceite y hollín generado durante la combustión. Mi experiencia es magnífica. Lo uso siempre y he podido comprobar que el aceite usado sale menos denso, lo que indica que liquidifica el aceite y hace que el limpiador llegue a más zonas del motor. En mi caso, aunque en las instrucciones simplemente se dice que se deje el motor al ralentí, yo uso el coche durante unos 20 Km para que haga más efecto. Por cierto, ni se os ocurra usar el producto y no hacer el cambio de aceite y de filtro posteriores (además de que el uso prolongado del producto puede dañar vuestro motor, sería como irse a hacer deporte y cambiarse de ropa después sin ducharse). Producto 100% recomendable que hace lo que promete. Tiene mis 10 este producto. 100% recomendable. 👍👍👍 #JJ'sLoRecomienda
