I've tried all the diesel additives, and this one is the best overall. I have noticed an improvement across the board, including mileage, Regens (longer), and EGR performance. Here are a few things I discovered with this product. I've had to use the double dose (2oz per 10 gallons of diesel) to get the improvements I'm seeing. I have a 2015 F-250 6.7. - 1-2mpg improvement, mostly on the freeway - Considerably lower soot levels sustained between regens (this is the best reason to buy this). I have an Edge CTS 3 to monitor all this stuff, which I highly recommend as well. - And related to the above, better EGR cooler performance. I got a warning of low EGR efficiency in Forscan (not enough to throw a code, but it would eventually) and cleared/removed it by running a couple of tanks of this stuff. Overall, I recommend this stuff. Not sure about the CP4 protection stuff.

My truck runs great on this stuff. When I ran out, I suffered through a few fuel related problems. Lower mileage as well. Hard to tell exactly if it was the cause or coincidence. I’m not going to risk it if I can help it. Every fill up. 2oz per gallon. Archoil oil additive (friction modifier) is really good science and metallurgy. Every other oil change. Older diesels need a “spa day” to keep them happy. 2006 e450 6.0.

Brand new 202e Ram 2500. Started using this with less than 2k on the ODO and averaged 15mpg. Started using this and literally jumped to nothing under 17mpg. Stock everything, nothing altered. Works for me!

I LOVE ALL ARCHOIL PRODUCTS! JUST HAVEN'T NOTICED A CHANGE IN MPG AS STATED WITH THE CLAIM OF THIS PRODUCT. BUT USE IT FOR THE MECHANICAL BENEFITS OF KEEPING INJECTORS CLEAN.

Using this to minimize stiction and add some lubricity to avoid HPFP failures. Much is made of these fuel additives (remember STP) and Lucas has been around forever but little about their capabilities is proven clearly enough for public consumption. Those tests that have been done give this a better than most opinion but that may not apply for all applications. Is see it as value because to date, no failures in my 500,000 miles of diesel truck use over 20 years. Longest application is on 175,000 mile Ford 7.3 PSD

Was on the fence of ordering this product. After some research I took the plunge. WOW!! We gained about 5mpg’s using archoil after two tank fills. So far very happy
