Archoil Diesel Fuel System Kit - AR6500 Diesel Treatment (40.6 oz) + AR6400-D Diesel Fuel System Cleaner

No creia que se sentiria diferencia, nunca crei que un simple tratamiento hiciera tanta diferencia, lo explicare, es mi primera vez, se lo aplique a un motor hdi de peugeot, el AR 6400-D es genial, mi coche tiene bolsa de urea, se llama eolys y el aditivo que le pongo al diesel es el que venden en peugeot un liquido simple y desoues de 185 mil km el coche comenzo a perder fuerza y dejo de oler al aditivo, se esforzaba mas en hacer lo adelantamientos o en subidas pronunciadas, por ese motivo investigue por meses en youtube, en foros, en varios lugares, ese producto no se consigue en una tienda en mexico y todo lo que vi era para pickup, pense que seria malo para mi motor pequeño, pero todo lo contrario mi 1.6lts hdi desde que llene el tanque de diesel y puse el AR-6400-D se sintio el cambio, estaba dudoso de que hubiera un cambio por que habia leido de otros aditivos y decian que no servian para nada, pero segui las instrucciones y desde el primer dia y los primeros 60km que hize, en ese mismo momento volvio el olor en el escape ese olor distintivo del eolys quemado, de la urea quemada, un olor a cloro, a los 20min del viaje, se sintio un empuje como si se destapara algo en el escape o algo funcionara mejor, y al dia siguiente se sentia mas lijero el coche, respondia un poco mejor, me acabe ese tanque de diesel en 1 semana y puse el AR6500 y en este primer viaje ahora huele mucho mas aun al aditivo y se siente muy lijero, se siente mas agil que antes, esta cosa me sorprendio, vale cada centavo, es lo mejor de lo que eh probado, lo volvere a comprar sin duda. El aditivo de peugeot es basura a comparacion de este en precio es mucho mas caro el archoil pero vale ese costo extra. Me encanto que llego bien empacado, en tiempo y forma, ningun problema.

There are two separate product reviews written below, but as a whole, I give this kit a 5-STAR review. 5-STARS This is a review on Archoil AR6500 Diesel Treatment. I am giving this product a 5-star review. This product decreased regen frequency from previous additive and also 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 extended more miles between regen intervals than previous additive used, and from baseline figure. I noticed an increase in mpg of 05-1.0 mpg one way in travel(downhill), and no signifigant change in uphill travel. I did not get any engine error codes while using this product. I used 7 ounces (high dose) with 35 gallons of fuel on one test, and on a second test I used 3.5 ounces (normal use) with 35 gallons of fuel. This is one of the most economical products to use with low ounce use per tank. 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. 1st test with double the normal dose at 7 ounces in 35 gallons of fuel: Mileage between regens decreased from 384 miles (baseline) to 362 miles(-22 mile decrease). The product that I used before Archoil was Cataclean. Archoil AR6500 product interval miles decreased from 414 miles (Cataclean), to 362 miles, a decrease of 52 miles. This test was a disappointment, as I was expecting more from Archoil AR6500 Diesel Treament. This is why I decided to perform a second test with normal dosage. 2nd test with normal dosage of 3.5 ounces in 35 gallons of fuel: Mileage between regens increased from 384 miles (baseline) to 564 miles (+180 miles increase). The product that I used before Archoil was Cataclean. Archoil AR6500 product interval miles increased with normal dose, from 414 miles using Cataclean, to 564 miles, an increase of +150 miles. This was the result that I was hoping for. Perhaps, use a high dose initially to clean, then use normal dose for regular use. Performance seemed to increase with less throttle input needed on acceleration or towing. So far in testing different additives, AR6500 is my favorite. Seafoam would be my second choice. The increase in DPF regen interval mileage and economy of use puts this product on top. There may be better, but I haven’t gotten there yet. Driving Notes: 32 miles driven during regeneration cycles (both tests) Soot down to 8 grams then 6 grams on second test EGTs = 556F temperature, normal highway driving EGTs = 675-700F temperature during regeneration cycle Injection quantity at idle at baseline=9mm Injection quantity at idle after AR6500=7mm #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: -0.6, 0.1, -0.1, 0.5, -1.1, 0.0, -0.1, 1.1 Less fuel being used at idle. Increase in mileage performance. Approx. +0.5-1.0 mpg Decrease in regeneration intervals: From baseline: longer distance between intervals +180 miles From previous additive (Cataclean): longer distance between intervals +150 miles Injector balance had mixed results between injectors. 4-STARS This is a review on Archoil AR6400-D Diesel Fuel System 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 (also Archoil product) used, but increased mileage form baseline figure. I did not notice any mileage changes. 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 12 ounce bottle in 35 gallons of fuel. Mileage between regens increased from 384 miles (baseline) to 462 miles (+78 miles increase). The product that I used before AR6400-D was AR6500. Archoil AR6400-D product interval miles decreased, from AR6500 at 564 miles, to 462 miles, a decrease of -102 miles. Driving Notes: 43 miles driven during regeneration cycles Soot down to 7 grams EGTs = 556F temperature, normal highway driving EGTs = 685F temperature during regeneration cycle Injection quantity at idle at baseline=9mm Injection quantity at idle after AR6400-D=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: -1.0, 0.6, 0.2, 1.0, -0.8, 0.0, -0.1, 0.0 Less fuel being used at idle. Mileage remained about same as baseline Decrease in regeneration intervals: From baseline: longer distance between intervals +78 miles From previous additive (AR6400-D): shorter distance between intervals -102 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.

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.

I'm sure it's a good product, did not add any value or mileage to my Duramax

Works great but still I'd consider it priced on the high end. It works though so if you need to clean a diesel system it's a safe but expensive bet.

Always amazing, I’ve sensed these take care of my truck for 50 k miles now, I’ve gotten through other brands but this has kept my fuel filters clean and has definitely given me better gas mileage and has given me cleaner fuel/10/10
