Liqui MolyPro-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.

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.

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

4-STARSThis 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 cyclesSoot down to 3 gramsEGTs = 505F temperature, normal highway drivingEGTs = 695F temperature during regeneration cycleInjection quantity at idle at baseline=9mmInjection quantity at idle after Liqui Moly Pro-Line=8mm#1 #2 #3 #4 #5 #6 #7 #8Injector balance at baseline: -0.5, 0.1, -0.2, 0.9, -0.6, -0.1, 0.0, 0.4Injector balance after additive: -0.8, 0.6, -0.3, 0.2, -0.9, 0.0, -0.1, 1.2Less fuel being used at idle.Mileage remained about same as baselineDecrease in regeneration intervals:From baseline: longer distance between intervals +60 milesFrom previous additive (AR6400-D): shorter distance between intervals -18 milesInjector 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.Regeneration Interval Mileage Comparison of Different Additives:baseline (no additive), 384 miles between regeneration intervalsArchoil AR6200 Fuel Treatment, 391 miles between regeneration intervals,+7 mile increase from baseline, +7 mile increase from previous additive(none, baseline)Wynn’s DPF Regenerator, 462miles between regeneration intervals, +78 mile increase from baseline, +71 mile increase from previous additiveSeafoam (high dose), 504 miles between regeneration intervals, +120 mile increase from baseline, +42 mile increase from previous additiveNitrox Clean Cat Diesel, 324 miles between regeneration intervals, -60 mile decrease from baseline, -180 mile decrease from previous additiveArchoil AR6500 pulling trailer in hot weather (not same comparison) , 1075 miles between regeneration intervals, +691 mile increase from baseline, +751 mile increase from previous additiveNitrox Clean Cat Diesel 2nd try, 402 miles between regeneration intervals, +18 mile increase from baseline, +78 mile increase from previous additive(Nitrox Clean Cat Diesel)Liqui Moly Diesel Purge, 265 miles between regeneration intervals, -119 mile decrease from baseline, -137 mile decrease from previous additiveWynn’s Turbo Cleaner, 298 miles between regeneration intervals, -86 mile decrease from baseline, +33 mile increase from previous additiveRislone Hy-Per Diesel, 323 miles between regeneration intervals, -61 mile decrease from baseline, +25 mile increase from previous additiveRislone DPF Clean, 323 miles between regeneration intervals, -61 mile decrease from baseline, 0 mile difference from previous additiveArchoil AR6500 pulling trailer in hot weather one way, cooler temps coming back(2nd trip, different route) (not same comparison), 680 miles between regeneration intervals, +296 mile increase from baseline, +357 mile increase from previous additiveCataclean, 414 miles between regeneration interval, +30 increase from baseline, +26 mile increase from previous additiveArchoil AR6500 Diesel Treatment, 564 miles between regeneration interval, +180 mile increase from baseline, +150 mile increase from previous additiveArchoil AR6400-D Diesel Fuel System Cleaner, 462 miles between regeneration interval, +78 mile increase from baseline, -102 mile decrease from previous additive Archoil AR6500.Liqui Moly Pro-Line Diesel Cleaner, 444 miles between regeneration interval, +60 mile increase from baseline, -18 mile decrease from previous additive Archoil AR6400-DStar Review Legend1 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 increase5 star: gained more than 100 miles in regen mileage interval (from baseline or previous additive), or +3 mpg increase.

I have used this on multiple small (25 hp) diesel engines in some sub compact tractors. Adding this to the fuel and then running the tractor for an hour or two while working vastly improved the how it idles after starting, less smoke as well. Definitely going to continue running this through the fuel a time or two each year.

Mi carro era peresoso y cuando utilice este producto mejoro de forma increible lo recomiendo
