Diesel Flush
EGR valve/sensor problem... guessed it worth a try rather than a £100 component replacement.
Recommend using when tank less than 1/4 full to get full effect, instructions don't actually give very much detail apart from this is good for 75l.
Took advice from a mechanic, and took car for a four gear run on the motorway for 10 miles... Hey presto sorted!
Easy to pour without spilage.Read full review

Overnight injector clean
I have used Liqui Moly on two occasions now to clean injectors and each time the result has been good.
What I did was to fill a new diesel filter with neat Liqui Moly, start the engine, run it for 30 seconds and then leave it overnight. The next day I took the car for a fast run down the motorway and this gave the injectors a good clean out.
The results were quite noticeable on my thirteen year old 149,000 mile car.

Cough medicine for a Sprinter
I finally managed to do a oil and filter service on my increasingly smokey and lumpy Sprinter.
Despite the new oil and fuel filters, the engine still produced quite a bit of smoke on initial start up, which would last for about 600 yards before clearing. A bit embarrassing really!
On the recommendation of my friend and neighbour, I tried a dose of Liquid Moly Diesel Engine Purge. I put a whole can in to about 25 litres of Diesel in the tank. I took a couple of trips on the motorway and a few miles to do its work but now my van is once again a ‘smoke free zone’.
Good product!Read full review

Superb Product
Fill diesel filter at change, then add remainder to tank.
Cleans injectors and improves combustion resulting in smoother running and better economy.

Intermittent ecu light, limp mode.
The fuel valve in my diesel pump was sticking and one injector was slightly out, ran this through the system, problem gone and engine pulls better than it has for a long time.

better perfomance
have used it over the years on my vw polo...instead of purging it the hard way by connecting to feed and return lines, I tend to prime my new diesel fuel filter with liqui moly...Its far quicker that the convensional way. Plus the fact it can be done twice with the same filter 6 months apart,just drain off the diesel thats in the filter,then top up with diesel purge.Read full review

Deisel Engine Cleaner
Reduced the hesitation in my car and the pinking sound I was experiencing beforehand. The engin seems to run more smoothly since it was used. I run the tank down low and put 1 tin in and ran the car that way. Then filled if up with the 2nd tin added. Didn't have the confidence to disconnect fuel lines and run 1st treatment out of the can.Read full review

Excellent value for money product
Car was hesitating a bit at tick over. I put diesel purge directly into a new fuel filter and idled the car for few minutes and presto, problem solved. Car is still running great with no hesitation. Excellent product. To top it off I still have some left for future applications if required.Read full review
