Pajero was hesitate and lack of power. Drained the fuel filter housing and topped it up with the purge fluid. Took for a run and noticed the difference. Definitely use this product again..

I am skeptical about any fuel additives, but this one really works. I disconnected my fuel lines and ran it straight from the bottle and have noticed considerable fuel economy improvements. Would definitely buy again.

Didn’t notice the same fuel economy as when I used the similar Penrite product but then again I think I was driving faster on the same 400km trip down the Hume Hwy. That chews more juice every day of the week. Averaged 92km/hr and 8.6L/100km in a Mercedes Sprinter campervan over the 400km.

I use it after every 10,000km service and it keeps my fuel, tank and engine clean, and fuel efficient. The product does as it states which is perfect and I couldn’t ask for anything more. I highly recommend regular use.
Excellent product. Immediate improvement in idle, and quieter operation. Engine now idles 100rpm higher from where it used to, meaning the injectors are clean now.
I wasn’t expecting anything in a bottle to make much if any difference but it did. I have a 20 year old 1HZ Landcruiser which was going ok prior but wanted to do some maintenance so I used the diesel purge. The engine is slightly quieter and is more efficient. Previously turning the car off would result in a rough engine clatter now is much smoother.
Poured half can into a full tank in my Nissan Navara and noticed the difference almost immediately.Car ran smoother and the fuel economy improved . Very good product. Will use it again.
Works extremely well, saved me doing a full engine clean as this product does exactly what it’s says. I have used it twice, really noticed the difference.I Recommend this product.
Quality product, German engineering. Been using Liqui moly for 20 years as a mechanic. Best stuff around. Don’t risk the cheap stuff, trust quality.
I used a borescope camera to check before and after using this product and it appears to be effective if used when your tank is around 1/4 full.The increased concentration dissolved and burnt off a lot of the gunk in the inlet valve area and the level of built up soot inside the EGR valve reduced significantly.My opinion is this stuff cleans the engine intake and inlet valve area if you put in a can every time you got down to the last 1/4 tank of diesel.I have a B180CDI thats done over 300,000km and was seriously gummed up.3 cans over 3 weeks and it’s suddenly a smooth quiet Mercedes’ again.
