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.

Great product
