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!

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

Good reputation for their products, delivered next day.

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

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

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.

Great quality

Good flush for my engine

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

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.
