Archoil AR6500 Diesel Treatment (40 Ounces) - Treats 400 Gallons - Additive for All Diesel Vehicles

Maybe there is such a thing as a mechanic in a can.I bought a Dodge RAM 2500 5.9 Cummins.It has 218k on it. I live off grid and drive 5.5 miles of slow going, country gravel road to get to my place. I felt the stutter in the engine going around curves and up hills at low speed and RPM. At this time I averaged 15.5 MPG on the factory digital display.I heard about this stuff from an old time that started using it in his old 99 RAM. I took his advice, and started using the full 3 part treatment . I've been consistently using all 3 products for more than a year now. I do the boost dose, 2oz per 10 gallons of diesel. My fuel economy has increased to average 17.4 MPG reading, there is absolutely no stutter at any speed or RPM. I'm NOT a mechanic, but I know a better running truck when I see it and drive it. I've got 248K now and this truck runs far better than it did the day I bought it thanks to a little TLC and the Archoil line.

My Turbo Actuator was defective I was only getting 2 lbs of boost. I started using Arcoil for a few weeks. My transmission went out on my 2018 2500 HD Ram, I took my truck to a reputable shop about 1 hour from my house. When I picked up my truck late evening I heard a whistling I haven't heard lately, I checked my boost gauge and noticed I was getting 8 lbs of boost, week after week my boost was going up to 18 lbs without changing my Turbo activator. My MPG had gone from 17.3 to 18.8 when pulling I was getting 14 MPG and now 15.5 MPG. Last week my new Turbo activator was installed. I will continue to be a Arcoil user !

I started using Archoil about 2.5 years ago, when I discovered the CV4 fuel pump issue on my 2021 F350's 6.7 diesel. I live in the Ozarks ans did see a slight increase in fuel mileage, but no big difference in mpg. I use it on every fill up and know I am doing it to reduce fuel pump risk.

Just finished my first bottle of archoil in my 2024 ram 2500. I noticed a slight increase in fuel mileage but I wasn’t doing the double dose to get the gains that’s advertised. But as far as my dpf filter goes, this has been great. I do a lot of in town driving and before I started using archoil my filter percentage would get up to 30% and regen frequently. Ever since I’ve put this in my dpf gauge hasn’t left 0%. Highly recommend

Works as expected

I will continue to buy this additive. My fuel mileage has increased by at least 10 percent and the engine doesn’t go into regeneration mode as often (2019 Duramax). Made a 100 mile round trip yesterday and got 23.5 mpg at 55 mph with some town driving included.

Why did you pick this product vs others?:Since diesel fuel has ZERO additives at the pump, this is a necessity. After extensive on-line research this product always rated at the top. The bottle stores securely and is simple to use with ability to add correct amount every time (1 ounce to 10 gallons fuel). Considering the cost of a new Super Duty, I only use the best products.

I decided to give this a try over the HotShots EDT. Like others have said, I have saw a 2-3mpg increase using this over the hot shots in my TDI. The longer neck is nice for being able to stick it in the fuel hole.
