LIQUI MOLY 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.

🔎 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.

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.

Bought this to flush out my Renault megane 2010 mkiii 1.5dci, was a bit sceptical but it has actually helped with reducing the noise of the engine, brilliant stuff, just followed the instructions on the tin highly recommended

Very impressed, actually leaves the engine clean was a bit of a sceptic with this but has proved me wrong.

Quality engine flush but don’t over use it - every 5th oil change it’s more than enough if you look after your vehicle and do service in time

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.

Perfect as always

Excellent product, it fixed Low oil pressure light in Lexus 1UZFE

Eccellente prodotto, si aggiunge all'olio motore (caldo), si lascia girare al minimo, con qualche piccola accelerata a 1200-1300 giri per farlo circolare bene, per10-15 minuti, poi si scarica l'olio esausto che sarà liquidissimo, sostituire anche il filtro dell'olio che sarà intasatissimo da tutti i detriti e depositi di olio che il prodotto a disciolto dal motore, riempire con l'olio nuovo. Il motore riacquisterà compressione perché il prodotto avrà rimosso anche le incrostazioni dalle fasce elastiche, nei diesel ridurrà la fumosità (nel mio caso azzerata su Golf 5 1.9 TDI), turbina e motore meno rumorosi e più brillante. Trattamento assolutamente da fare ad ogni cambio d'olio!

Best for engine with turbo charger and super charger.
