Review: 93000 mile, 15 year old Audi BWA engine - cleaned and restored! - 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.
Review: Not Snake Oil! - 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!

## Questions & Answers

**Q: How to apply it?**
A: It’s a flushing fluid that you add to the engine oil before you change it.
You warm up the engine, add the liquid moly. Idle  for about 10 and then drain the oil as normal.
However you must chain the filter as well because this will be contaminated with the flushing fluid/oil mix....

**Q: when i need to mix with oil.  After warm up engine Or before warm up engine. How long time..?**
A: As far as I remember you run the the engine to operating temp so all the oil has circulated throughout the oil channels. Then switch off the engine.
Add the contents of the liqui moly pro-line engine flush and start the engine. Do not rev the engine and let it idle for 10 mins.
Then drain oil and change the oil filter as normal.

**Q: Is this okay for a vauxhall mokka 1.7cdti manual transmission?**
A: Hi, absolutely, you can use the Liqui Moly Pro Line engine flush with confidence at your next oil change! 
Kind regards,
Funky Autoparts

**Q: Can you mix the hydraulic lifter with the engine flush fluid?**
A: U use engine flush in engine after it warm for ten min . Drain then put new oil in then put hydraulic lifter in. Try liquid moly mo2 . That work brilliant .

### ⭐⭐⭐⭐⭐ Added protection.
*by N***N on 25 November 2025*

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.
