Liqui-Moly Diesel Purge Injection Cleaner (500 ml 16.9 oz set of 2

Very effective in cleaning injectors. No more hesitation or pinging. Will now use Diesel Purge after each fuel filter change .

Used on my 1983 Mercedes 240D. I am a believer! Follow the directions and it cleaned my system. Now I’m able to drive at normal speeds with no hesitation. Make sure to change your fuel filters.

Wish I could fill up the gas tank with this stuff! It makes a diesel run the smoothest you've ever seen! Run both cans directly through the system at the engine for best results.

I use hotshot's secret daily treatment, but mileage and response always seem to be a bit better after using this product. I have used it in 3 different generation of TDi and a 2014 Cruze diesel and they all respond to it. It's the go to for once a year cleanings.

I run this flush in my VW tdi CJAA when I change my fuel filter at 20k miles. Poor it directly into the fuel filter houseing. It always makes the engine run smoother and I usually pick up 1 or 2 mpg. Great products that really do help performance and drivability.

It does what is suppose to do.

All of Liquimoly products are great and their customer service is excellent too. Good price and fast delivery!

My Toyota diesel was acting like it was missing and it would stumble and buck going down the highway. I replaced the fuel filter twice with no improvement. I searched the blogs for my symptoms and they all said to use this this stuff. Fill a new fuel filter with this stuff and start the engine. In less than 5 minutes the engine made less noise and very little smoke whereas before the smoke was very noticeable. The power is up about 50%! I could not believe it. The engine runs like a sewing machine going down the road. Buy it and use it!

Possiedo una Opel Corsa D 1.3CDTi in ottimo stato d'uso (una "stradista" perché circola sempre su autostrade o Strade Statali) ma con circa 300.000Km. 3 anni fa un Officina autorizzata ha rigenerato il DPF che ancora oggi funziona e si rigenera regolarmente. Da qualche mese però la Valvola EGR comincia a dare qualche segno e sicuramente sarà ormai satura di carbonio o altre schifezze. Con additivo per gasolio di altra marca (che non mi pare il caso di nominare), la spia motore nel cruscotto si spegne dopo aver percorso circa 30Km. Ho poi quindi provato Liqui-Moly diesel Purge versandolo direttamente nel serbatoio (praticamente a secco di gasolio, ovvero non più di 3 litri). Fatti diversi Km fino ad esaurire l'additivo stesso ed il carburante, mi aspettavo che l'azione "purge" dell'additivo facesse vedere i suoi effetti, ma purtroppo la spia motore è rimasta accesa sempre. In pratica non ho riscontrato alcun miglioramento con l'impiego di Liqui-Moly diesel Purge.

Alles Top

Wow! What a difference. When my car sat for a few days and it was cold out, my car would start hard and run rough for a minute or two. And, there would be a puff of blue smoke. When I changed the fuel filter I used a turkey baster to empty all of the fuel from the cartridge. Filled it with this product and started the car. I ran it a bit and now the car works great. I'll buy again!

Does what it says on the can,

Follow the directions, this stuff works like intended, my tired diesel now wakes up faster, sounds smoother. Highly recommended.
