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 testEGTs = 556F temperature, normal highway drivingEGTs = 675-700F temperature during regeneration cycleInjection quantity at idle at baseline=9mmInjection quantity at idle after AR6500=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: -0.6, 0.1, -0.1, 0.5, -1.1, 0.0, -0.1, 1.1Less fuel being used at idle.Increase in mileage performance.

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 cyclesSoot down to 7 gramsEGTs = 556F temperature, normal highway drivingEGTs = 685F temperature during regeneration cycleInjection quantity at idle at baseline=9mmInjection quantity at idle after AR6400-D=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: -1.0, 0.6, 0.2, 1.0, -0.8, 0.0, -0.1, 0.0Less fuel being used at idle.Mileage remained about same as baselineDecrease in regeneration intervals:From baseline: longer distance between intervals +78 milesFrom previous additive (AR6400-D): shorter distance between intervals -102 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.Star 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.

    5.0 out of 5 stars Pretty Amazing Product

    J.B. · May 18, 2025

    I don't write many reviews, and I am NOT affiliated with the company in any way. I have used the Archoil 6400 before and was very impressed with how well it worked. It definitely reduced the frequency of the regens on my 2013 F350 6.7L. I was having regens every 150-200 miles and getting engine codes thrown for restricted flow. Put in the 6400 before going on a long road trip and what a difference it made. Regens now happen 400+ miles apart, and no more codes!I've got the dreaded CP4 fuel pump, as most Ford diesels do. Their nemesis is ultra low sulphur diesel. No lubrication in the fuel. I added a dose of the 6500 yesterday and went for a 30 mile drive. By mile 6 or 7 I could feel the engine ran much smoother. Not just a little bit, but WAY smoother. Acceleration seemed to be stronger too. I'm just a regular guy and not a mechanic, but I know when I my truck is running better, and these two additives have made a big difference.

    5.0 out of 5 stars Awesome Product

    C. · June 4, 2025

    Great Product I drive a 2018 Chevy 5500xd with a 5.2 Deisel for my business its cut down the regen down to 1 time every 3 days when before it was doing a regen 2 to 3 times a day. I have noticed a increase in the throttle response. I haven't noticed a increase in fuel economy but I really wasn't expecting that part because the size of the vehicle but over all great product if I get a Deisel pickup I will definitely be using this product

    5.0 out of 5 stars Good stuff

    T. · June 22, 2025

    The first 3 years I owned my diesel pickup the particular matter sensor had to be replaced. Since using this product for the last 2 years, I have not had any check engine lights thus far so it seems to be doing something right.

    5.0 out of 5 stars Skeptic turn to believer

    A.W. · June 14, 2025

    This is the best days of your additive that I have ever run. I have seen improved fuel mileage and also less regenerations. I was skeptical about getting it at first, but I will be running this from now on.

    4.0 out of 5 stars One of the better diesel additives.

    R.P. · March 11, 2025

    The Diesel Treat does seem to live up to it's reputation as one of the best. Not sure the cleaner has any measurable effect.

    5.0 out of 5 stars It works.

    J.V.P. · June 20, 2025

    I’m still on the initial cleaner treatment, but yes I see a difference in mpg, from 13.5mpg to 14.5mpg local city driving, not towing….

    5.0 out of 5 stars Fantastic product

I have a 2024 dirmax, 3 l. And since using this, I've seen a Decrease in my region cycles.I've seen a bit more power 2.I think this is a very good product. I've been using.This over 6 months now. And you can use this in winter diesel if you're diesel's already treated. The injection cleaner is also a very good product. Use the injection cleaner once every oil chanvery satisfied

    Great products

    Works great

    Worth the money great product

    G.L. · April 22, 2025

    Truck ran decent , used this stuff truck ran great after . Worth the money

    Felt a difference right away! but Pricey

    M. · July 7, 2024

    This product is too expensive!But it did work right away.. felt power return to my Diesel.The Diesel treatment is great as it also last a while using only oz's per tank.The Fuel system cleaner, which is what we need multiple times and every tank, ideally, isone whole bottle per tank... THIS IS WHERE IT IS OVER PRICED.(would love to find another product that works well and doesn't COST so much)Sad the Manufacturer/suppliers doon't lower to capture the needed market on this, as I wouldcertainly buy more if it was reasonable.

    Thumbs up from me

    T. · April 17, 2025

    Still on the cleaner , noticed an improvement with less than half a tank used.

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.Star 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.

    I don't write many reviews, and I am NOT affiliated with the company in any way. I have used the Archoil 6400 before and was very impressed with how well it worked. It definitely reduced the frequency of the regens on my 2013 F350 6.7L. I was having regens every 150-200 miles and getting engine codes thrown for restricted flow. Put in the 6400 before going on a long road trip and what a difference it made. Regens now happen 400+ miles apart, and no more codes!I've got the dreaded CP4 fuel pump, as most Ford diesels do. Their nemesis is ultra low sulphur diesel. No lubrication in the fuel. I added a dose of the 6500 yesterday and went for a 30 mile drive. By mile 6 or 7 I could feel the engine ran much smoother. Not just a little bit, but WAY smoother. Acceleration seemed to be stronger too. I'm just a regular guy and not a mechanic, but I know when I my truck is running better, and these two additives have made a big difference.

    Great Product I drive a 2018 Chevy 5500xd with a 5.2 Deisel for my business its cut down the regen down to 1 time every 3 days when before it was doing a regen 2 to 3 times a day. I have noticed a increase in the throttle response. I haven't noticed a increase in fuel economy but I really wasn't expecting that part because the size of the vehicle but over all great product if I get a Deisel pickup I will definitely be using this product

    The first 3 years I owned my diesel pickup the particular matter sensor had to be replaced. Since using this product for the last 2 years, I have not had any check engine lights thus far so it seems to be doing something right.

    This is the best days of your additive that I have ever run. I have seen improved fuel mileage and also less regenerations. I was skeptical about getting it at first, but I will be running this from now on.

    4.0 out of 5 stars One of the better diesel additives.

    The Diesel Treat does seem to live up to it's reputation as one of the best. Not sure the cleaner has any measurable effect.

    5.0 out of 5 stars It works.

    I’m still on the initial cleaner treatment, but yes I see a difference in mpg, from 13.5mpg to 14.5mpg local city driving, not towing….

I have a 2024 dirmax, 3 l. And since using this, I've seen a Decrease in my region cycles.I've seen a bit more power 2.I think this is a very good product. I've been using.This over 6 months now. And you can use this in winter diesel if you're diesel's already treated. The injection cleaner is also a very good product. Use the injection cleaner once every oil chanvery satisfied

    Truck ran decent , used this stuff truck ran great after . Worth the money

    Felt a difference right away! but Pricey

    M. · July 7, 2024

    This product is too expensive!But it did work right away.. felt power return to my Diesel.The Diesel treatment is great as it also last a while using only oz's per tank.The Fuel system cleaner, which is what we need multiple times and every tank, ideally, isone whole bottle per tank... THIS IS WHERE IT IS OVER PRICED.(would love to find another product that works well and doesn't COST so much)Sad the Manufacturer/suppliers doon't lower to capture the needed market on this, as I wouldcertainly buy more if it was reasonable.

    Thumbs up from me

    T. · April 17, 2025

    Still on the cleaner , noticed an improvement with less than half a tank used.
