Great Product

This is my first time having this product and I thought that products like these were a rip off. However, I have about 11,000 miles on my truck, and I am certain that I have maintained all of the power because of this product. The only complaint that I have is if you don’t have a flex nozzle of some sort this product, when you pour it into your fuel system, runs all over the place. Other than that no complaints.

Fair price. I wish the neck of the bottle was a bit longer though

I can’t speak to the effectiveness of this product since my truck is fairly new.However, I learned the hard way that the container must be shoved all the way into the fuel filler neck.Apparently there is an drain near the fuel cap. So when I went to dump this in the tank, I failed to get the whole bottle inside, and I lost about a quarter of liquid. It poured all over my garage floor. And dropped down the underside of my truck.Use a long funnel or be sure to shove the entire bottle into the fuel tank as far as it’ll go.

Just right for my needs

It’s easy too usePrice is a little high though.

Didn’t notice any difference is mileage or power. The owners manual says to only use this but it isn’t easy to find.

5-STARSThis is a review on AC Delco Fuel System Treatment Plus-Diesel. I am giving this product a 5-star review. I used one, 12 ounce bottle mixed with 15 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 and vehicle working properly.This product decreased regen frequency (good) from previous additive and decreased frequency (good) from baseline, which may suggest that it allows engine burn cleaner or more efficiently, and slowing down soot production. This product had an increase in miles between regen intervals than previous additive (Dura Lube Severe Catalytic and Exhaust Treatment), and an increase in miles between regen interval from baseline figure as well. As far as mileage goes, I got mixed results. MPG was the same at 20.7mpg on both uphill and downhill routes. On uphill route, mileage increased by +2.7 mpg. On the downhill route, mileage decreased by -1.6mpg. I did not get any engine error codes while using this product.Mileage between regens increased from 384 miles (baseline) to 425 miles (+41 mile increase)(good).The product that I used previously was Dura Lube Severe Catalytic and Exhaust Treatment.AC Delco Fuel System Treatment Plus-Diesel increased interval miles from previous additive, 282 miles, to 425 miles (+143 miles)(good)When using any DPF cleaner or additive, I would try to incorporate a regen cycle during use and go on longer drives on highway or freeway to increase the EGTs to burn off the soot.Driving Notes:29 miles driven during regeneration cyclesSoot down to 8 gramsEGTs = 592F temperature, normal highway drivingEGTs = 692F temperature during regeneration cycleInjection quantity at idle at baseline=9mmInjection quantity at idle after AC Delco Fuel System Treatment Plus-Diesel=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: -0.5, 0.1, 0.1, 0.4, -0.8, 0.8, 0.5, 0.2Less fuel being used at idle.Mixed results in MPG:Decrease in regeneration intervals frequency:From baseline: increased distance between intervals +41 miles (good)From previous additive (Dura Lube Severe Catalytic and Exhaust Treatment):increase in distance between intervals +143 miles (good)Injector balance seemed about 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 few 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, vehicle speed or stop and go traffic(big factor), 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-DLiqui Moly Diesel Particulate Filter Protector, 625 miles between regeneration interval, +241 mile increase from baseline, +181 increase from previous additive Liqui Moly Pro-Line Diesel CleanerLiqui Moly Super Diesel Additive, 533 miles between regeneration interval, +149 mile increase from baseline, -92 mile decrease from previous additive Liqui Moly Diesel Particulate Filter ProtectorDura Lube Severe Catalytic and Exhaust Treatment, 282 miles between regeneration interval, -102 mile decrease from baseline, -251 mile decrease from previous additive Liqui Moly Super Diesel AdditiveAC Delco Fuel System Treatment Plus-Diesel, 425 miles between regeneration interval, +41 mile increase from baseline, +143 mile increase from previous additive Dura Lube Severe Catalytic and Exhaust TreatmentDura Lube Diesel DPF and Catalytic Treatment, 360 miles between regeneration interval, -24 mile decrease from baseline, -65 mile decrease from previous additive AC Delco Fuel System Treatment Plus-DieselStar 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.
