Great product! Highly recommended!

Wow!
First time using Liqui Moly additive for diesel fuel and I am now sold on it!
I developed a laquer problem earlier this year in my 5-ton truck's fuel system. While I addressed the issue in general, the throttle shaft in my IP was still "sticky" and slow to return to idle. I was not able to solve the sticky throttle with other products and I did not want to tear into the pump if I did not need to. I had read some very good comments and reviews on-line about Liqui Moly working in situations like mine and decided to give it a try.
I dropped my fuel filter, filled it with the Liqui Moly, reinstalled and fired up the big Cummins. Literally within 30 seconds the additive cleared out the deposits inside the IP and the throttle action was back to normal.
Great product! I highly recommend it!

Engine runs quieter.

If used more concentrated , when you have little diesel left in your tank add a litre of the additicve and drive till you are just about empty, it really works. My engine use to give lots on smoke on start-up, now there's very little, and the engine runs quieter and smoother. My engine is a 1976 300D. I'm really pleased with this product.Read full review

Good medicine for old diesel

I use 500ml diesel purge for my loved W124 300tdt with 400,000km. I have already cleaned and adjusted diesel injector by surgery but could not even touch fuel injection pump. This medicine with surgery method is perfect fit to my engine and could feel the result immediately . It was -30C this morning but she started immediately without any hesitation. I can strongly recommend this medicine.Read full review

Good product

Used this in my 93 diesel engined Merc. Added it neat to one of the fuel filters when I changed it out.
After starting the engine and running it through the engine it ran quieter and subsequent starts produced less smoke.
Recommend the product.

must for all diesel owner

After cleaning injectors by separating and cleaning completely,all you can do is using medicine so that you can clean injection pump,pipes also injectors with adding miles after surgery.
