It does what it says. My 6.0 Powerstroke would run rough during the cold start up in the morning when it was below 40 degrees. I poured this directly into the secondary fuel filter under the hood and carefully put the filter in. The remainder I put into the tank along with an additional can. I drove it for 50 miles.I can tell you it ran a lot smoother on the initial cold start up the next day and it was only 6 degrees Fahrenheit.

Great, does the job as described, one of the best brands for this stuff, wouldn't go with any other option when it come to a diesel cleaner.

This worked great on my L3130. There was a slight miss at mid to higher rpm's affecting power some. Had been trying some other stuff with limited success. I dumped one can into the tank with maybe a gallon of diesel left and went out mowing. This cured the issue. I would recommend this, Seafoam and Power something did very very little previous to this.

1984 Vw Jetta turbo diesel had trouble starting on cold. I pour the whole can directly into my fuel filter bow, ran it for 30 min at addle , car note starts right away. So far it’s been good for 2 months. Stuff works. I’m planing on doing one more time just to be sure it’s cleans everything. Please read instructions for best results.

Did fuel filter change on my VW TDI and filled filter housing and primed system. Started vehicle and this stuff cleaned and silenced the engine idle within seconds. Much better response and gained a couple miles to the gallon on commute after service. I will be using this every fuel filter change.

Added this product to my 2013 TDI, and it's running like a top now. Had a slight stutter prior, but now it's purring!

During a recent fuel filter change in my 2005 VW Jetta TDI wagon (with over 207k miles on the original BEW engine) I poured in a full can of Diesel Purge (nearly filling the filter to the brim), reconnected hoses, then drove several miles while varying engine RPM as recommended. Then filled the fuel tank (which had been run nearly empty to reduce dilution while purging) and an improvement in performance was immediately apparent; faster acceleration and no more smoke when starting. I'll save the second can for next year's PM.

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.

Der Diesel Einspritzsystem Reiniger hält was er verspricht. Mein alter 300 D raucht nicht mehr und hat deutlich bessere Leistung als zuvor, der Motor läuft deutlich ruhiger und rund.
