After reading great reviews I thought I’d put this in when I did my last service. Since then if my Ute has been sitting for 12+ hours it starts then stalls and is really hard to start and I have to manually prime it, not sure if it caused the issue but I have never had the problem until using this, there was no noticeable difference in how it ran, maybe I got a bad batch? Other people seem to have no issues with it

Started to get an injector error. When looking up the code the remedy was going to require a new injector or an electrical fix. Thought I would try the injector cleaner before laying out big money. After about 120l with the cleaner the code has not reappeared. Highly recommend trying before taking to a repairer.

Purchased Liqui Molly Diesel injector cleaner as the 200 series cruiser was rattling. After using half the bottle with 30 litres of diesel the rattle began to quieten. Used the next half of the bottle with 20 litres. A big difference has been detected. I was hesitant in using any types of additive, i will now be confident to use a full bottle as prescribed by the directions on my next fuel fill.

Recently my mazda bt 50 2007 started giving a knocking sound.. found the knocking coming from injector. Each injector cost was over $900. Used this product after 2mins the knocking just disappeared.. high recommended. Thanks
I ha a Nissan YD25 and was pushing black smoke out the back on takeoff lots more than usual. Put this in with about half tank of fuel and within about 20-50klms of driving black smoke reduced a lot to almost not noticeable which is about normal for these engines.
I am an engine reconditioner since 1975.Always owned petrol cars.This my first diesel landchruiser with over 350,000 kilometres on it with an unknown history and felt kind of slugish for a 4.2 turbo engine but everyone said it was just an 80 series landcruiser thing / well I got 2 x Liqui Moly Diesel Injector Cleans and put it in with a full main and sub tank.I couldn't believe how quick it started working and just keeps getting better.With 200ks done since, now I can hear the turbo spool up and wow, that waist gate sound.Given the unknown history of this car I can only think the fuel system was so gummed up and now is running clean, this has saved me a very extensive pump and injector overhall, to say "I'M Impressed would be an understatement.Thanks the staff ... MoreI am an engine reconditioner since 1975.Always owned petrol cars.This my first diesel landchruiser with over 350,000 kilometres on it with an unknown history and felt kind of slugish for a 4.2 turbo engine but everyone said it was just an 80 series landcruiser thing / well I got 2 x Liqui Moly Diesel Injector Cleans and put it in with a full main and sub tank.I couldn't believe how quick it started working and just keeps getting better.With 200ks done since, now I can hear the turbo spool up and wow, that waist gate sound.Given the unknown history of this car I can only think the fuel system was so gummed up and now is running clean, this has saved me a very extensive pump and injector overhall, to say "I'M Impressed would be an understatement.Thanks the staff at Supercheap Clontarf QLD and Liqui Moly Diesel Injector Clean.I only wish that the 80 series had been on a dyno so a back to back reading could have been recorded
Liqui Moly been good for cars trucks and other vehicles I've this and other Liqui Moly products for years now made in Germany. So we all know Germany engineering.
Excellent diesel injector cleaner ! I've been using redline injector cleaner for petrol cars but couldn't find one one that works effectiviely for diesel until I came across this.
Brought this as an addition to my oil change for Terry & Ranger.Terry I did first, and without even realising the kids mentioned that the car was heaps quieter, to the point of not even noticing the other begins when cruising.Next was the Ranger about a week later,Also a noticeably quieter. It is only under very heave acceleration that the engine sound filters through.On general run around a it is quiet & smooth.Brough on catalogue special so yes, it was worth it.
excellent product. due to clogged injectors I blew up a 2013 hilux motor. at 120,000 kms Replacement motor and injectors were over $13,000. Current motor has over 100,000 ks with no sign of injector damage. If you have a hilux this is a lifesaver.
