Liqui Moly Pro-Line Diesel Cleaner, blue , red, 500ml (2032)

Ran a bottle of this through my 2005 TDI VW. The car has 200K miles on it and after using this product, the car seems to start easier and got a bit more mileage out of a tank of fuel.

I use this diesel additive on road trips or every other oil change. ROAD trips I will pack 2 bottles, 1 for on the way and 1 for on the way back. I believe it does assist in increasing MPGs as I have seen an increase in MPGs. 2024 Silverado 1500 3.0 Duramax

Added to our 2013 Sprinter after a fuel filter change. Runs niiiice and smooth. I will buy again on our next filter change.

4-STARS This is a review on Liqui Moly Pro-Line Diesel Cleaner. I am giving this product a 4-star review. This product increased regen frequency from previous additive but decreased frequency from baseline, which suggests that it may have cleaned the DPF to some degree or enhances combustion action to burn cleaner. This product lessened miles between regen intervals than previous additive (Archoil product), but increased mileage form baseline figure. I did not notice any mileage changes. Most of the time, power seemed to increase with less throttle input, but one day the engine seemed a little sluggish. Engine seemed to run smoother. I did not get any engine error codes while using this product. No check engine lights came on. Vehicle showed no adverse affects from additive. Regen mileage interval with NO additives was 384 miles after receiving vehicle from repair shop. I used one 500mL bottle in 18 gallons of fuel. Mileage between regens increased from 384 miles (baseline) to 444 miles (+60 miles increase). The product that I used previously was AR6400-D. Liqui Moly Pro-Line Diesel Cleaner decreased in interval miles from previous additive, 462 miles, to 444 miles (-18 miles) Driving Notes: 30 miles driven during regeneration cycles Soot down to 3 grams EGTs = 505F temperature, normal highway driving EGTs = 695F temperature during regeneration cycle Injection quantity at idle at baseline=9mm Injection quantity at idle after Liqui Moly Pro-Line=8mm #1 #2 #3 #4 #5 #6 #7 #8 Injector balance at baseline: -0.5, 0.1, -0.2, 0.9, -0.6, -0.1, 0.0, 0.4 Injector balance after additive: -0.8, 0.6, -0.3, 0.2, -0.9, 0.0, -0.1, 1.2 Less fuel being used at idle. Mileage remained about same as baseline Decrease in regeneration intervals: From baseline: longer distance between intervals +60 miles From previous additive (AR6400-D): shorter distance between intervals -18 miles Injector balance seemed relatively the same. My review is based on product efficiency, any damages to vehicle, check engine lights turning on or off, ability to clear engine codes (if my vehicle has any check engine lights), increase or decrease in mileage, and increase or decrease in regeneration mileage intervals. I will not use price as a factor. You will have determine if product is worth the cost. These products may or may not save you costly repairs or replacement. I cannot determine if these products can or will damage your vehicle. My vehicle has no check engine light or error codes. My vehicle is in good working order with no current issues during this review. My vehicle has over 200,000 miles. This is a stock vehicle, with a stock (OEM) factory tune installed. Just prior to this test, my truck was not performing a regen cycle. Repairs were done which included a new 9th injector, new DPF pressure monitor. The pressure monitor measures pressure before and after the DPF filter. The difference in pressure allow computer to estimate how much soot has accumulated in the DPF filter. A force regen was also performed on my vehicle and a passive regen performed before I received my vehicle from repair shop. Vehicle is performing as it should. Test drive is relatively the same and consistent. 49.5 miles one way, with a drive time of about 56 minutes. There is a gradual 1129 foot elevation gain one way and 1129 elevation loss the opposite way. There is some surface street driving, some freeway driving, and most of drive is highway. Hope this review helps. I will be writing more reviews on other diesel additives. I have some data from other additives for comparison listed below. Most products seemed to help and a couple seemed to worsened DPF performance during testing. You should not compare the towing data for comparison. I have just added it to show that towing will change data. Towing will increase exhaust gas temperatures and should make the DPF more effective. My regen mileage intervals increased, decreasing regen frequency, while towing. There are many factors that affect the DPF performance. The factors that I noticed (on my vehicle) are outside temperature, humidity, and EGTs. Lower temperatures decreased DPF performance. Higher humidity decreased DPF performance. Higher outside temperatures and lower humidity seem to increase DPF performance. Higher EGTs such as towing increased DPF performance. Longer driving distance seems helps the DPF filter as optimal temperatures are reached. It seems like soot accumulates faster when the engine and DPF filter are not warm/hot enough, and faster within the first 10-15 miles of travel. If you are only making short trips then the DPF will fill up faster and regens will be more frequent.

Liqui Moly Pro-Line Diesel Cleaner, 444 miles between regeneration interval, +60 mile increase from baseline, -18 mile decrease from previous additive Archoil AR6400-D Star Review Legend 1 star: Made check engine light turn on or trigger error code(s) 2 star: Causes no check engine warnings and no engine error codes. Mileage worsened or DPF regeneration intervals decreased in mileage. DPF regeneration process worsened. 3 star: gained less than 50 miles in regen mileage interval (from baseline or previous additive), or slight increase in mpg. 4 star: gained more than 50, but less than 100 miles in regen mileage interval (from baseline or previous additive), or +2 mpg increase 5 star: gained more than 100 miles in regen mileage interval (from baseline or previous additive), or +3 mpg increase.

Easy to use

This is a must for all German turbo diesel engine. Porsche BMW Volkswagen Audi Mercedes this is a must for all German turbo diesel owners

always seem to have good results from anything liquid moly makes. I use a preventive mx so not sure if it will fix a clogged injector or not, but I have over 70k miles on ecodiesel with good results so far.

El cambio en la función del motor es impresionante tenía advertencia de falla en precalentadores y disminución de la presión en el banco 1 en una Q7 y solo el cambio de filtro de combustible y Liqui moly corrigieron las fallas de otra forma en la agencia me inventarían que era necesario cambiar bomba de combustible inyectores etc por experiencias previas prefiero hacer personalmente el mantenimiento con la ayuda siempre de Liqui Moly

works well in my 2017 Range Rover and saves 2% better milage.
