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

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!

I will use it again. I’ll keep my system clean.

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.

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.

It does what is suppose to do.

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.

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.

Good price and product highly recommended by mechanic
