Great fuel additive, easy to use

Put two bottles into my 36gal diesel tank of my GMC Sierra 2500HD. After about a half tank I really noticed a difference in the throttle response. I’ve tried other products in the past and never felt a difference but there was a noticeable difference with this one! Will definitely use again every 6-12 months going forward.

This is a good product for the purpose it was designed for

4-STARSThis is a review on Liqui Moly Truck Series Complete Diesel System Cleaner. I am giving this product a 4-star review. This product decreased regen frequency from previous additive and slight increase from baseline, which suggests that it may have cleaned the DPF to some degree or enhances combustion action to burn cleaner. This product extended more miles between regen intervals than previous additive used, from prior tank with no additive, and from baseline figure. I noticed an increase in mpg of 0.85 mpg one way in travel(downhill), and an increase of 1.5 mpg in uphill travel. I did not get any engine error codes while using this product.I used 1 bottle of Liqui Moly Truck Series Complete Diesel System Cleaner, 16.9 oz. I added the bottle to 36 gallons of fuel.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. Mileage between regens increased from 384 miles (baseline) to 388 miles(+4 mile increase). The mileage between regens with no additive on the tank before this additive produces low interval miles, at 252 miles. This additive produced an increase of 136 miles from previous tank (with no additive). The product that I used before my empty tank run was Rislone DPF Clean, Exhaust & Emissions System Cleaner. This Liqui Moly product interval miles increased from 323 miles (Rislone DPF Clean), to 388 miles, an increase of 65 miles. I did not notice any improvement in power.Driving Notes:33 miles driven during regeneration cycleSoot down to 8 grams.EGTs = 556F temperature, normal highway drivingEGTs = 698-721F temperature during regeneration cycleInjection quantity at idle at baseline=9mmInjection quantity at idle after Liqui Moly=7mm #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: -0.7, 0.0, -0.5, 1.1, -0.8, 0.3, -0.4, 0.8Less fuel being used at idle.Increase in mileage performance. Approx. +1.1mpgDecrease in regeneration intervals:From baseline: longer distance between intervals +4 milesFrom previous tank: longer distance between intervals +136 milesFrom previous additive (Rislone DPF Cleaner): longer distance between intervals +65 milesInjector balance seemed to slightly worsen(not by much).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.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 additiveStar 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.

Put it in. Haven’t seen the effect yet. It’s gonna be a little bit.

Le he usado repetidas veces. Es un producto de muy buena calidad.Recientemente volví a ordenar este producto.

2007 F250 6.0Used conventional oil and 2 cans of this product.Motor runs quiet and help with stiction.And the price is better than all the other products I have tried.
