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.

Great product

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

Its Liqui Moly, of course is good. Does it work, who knows? Worth the money when doing your own oil change? Of course it is.

Perfect as always

Best for engine with turbo charger and super charger.

Excellent product! Works very well.

Como alguien que se preocupa por el mantenimiento preventivo del coche, el uso de un limpiador de cárter antes de cambiar el aceite es un paso que nunca me salto. En esta ocasión he utilizado el Liqui Moly Motor Clean (2427) en un motor 1.6 TDI con 100000 kilómetros, y los resultados visuales al vaciar el cárter son impresionantes. Proceso de aplicación: El uso es muy sencillo pero requiere seguir las instrucciones al pie de la letra: 1. Con el motor a temperatura de servicio, se añade el contenido de los 500 ml al aceite viejo. 2. Se deja el motor al ralentí durante unos 10-15 minutos (importante: no circular con el coche, solo dejarlo encendido parado). 3. Se procede a realizar el cambio de aceite y filtro de forma habitual. Observaciones y eficacia: Lo que más destaca es cómo sale el aceite viejo. Al usar este producto, el aceite drena con una fluidez mucho mayor y sale notablemente más oscuro y "sucio" de lo habitual. Esto confirma que el producto ha hecho su trabajo disolviendo los lodos, barnices y depósitos carbonosos que se acumulan en las paredes internas y en los segmentos de los pistones. - Resultados tras el cambio: Tras poner el aceite nuevo y el filtro, he notado que el aceite tarda mucho más en oscurecerse (permanece limpio en la varilla más tiempo), lo que indica que el motor estaba realmente limpio por dentro. - Sonoridad: He percibido una ligera mejora en la suavidad del motor al ralentí, posiblemente debido a que los conductos de lubricación ahora están totalmente libres de obstrucciones. Seguridad: Una de las razones por las que elijo Liqui Moly es la confianza que ofrece la marca. A diferencia de otros limpiadores más agresivos, este producto es respetuoso con las juntas, retenes y sellos del motor, por lo que no hay riesgo de provocar fugas tras su uso si el motor está en buen estado. Actualizacion 2 meses despues de la compra: He vuelto a hacer un cambio de aceite y se nota que ha mejorado en algo la vida del aceite de mi motor y siento que podria haber apurado un poco mas los km hasta el siguiente cambio de aceite, realmente se nota la diferencia
