I have a 2011 BMW 335d with 170k miles on it. Since just after I purchased it with 70k miles, the check engine light has been on and off. I have spent thousands of dollars chasing ghosts trying to get the damned thing to go out. Earlier on I found some fuel additives would smooth out the idle and after time the light would go out. It inevitably would come on after a hard pull or some random time later. I won’t bore you with the amount of parts swapped and shop visits to date, but after this (the third to be fair) bottle of Archoil, the light has been off for a week so far and the idle has remained more or less smooth. To be honest I did also change the brand of fuel I and using about two months ago. Not sure if that had something to do with it.Almost immediately after adding it to my fuel, the car ran smoother and was more responsive. I’m not sure if the fuel economy improved at all with the application, but the car ran much better. Hope that wasn’t just a perceived improvement. One OBD code that I had was a DPF error (BMW 452A: DDE info- particulate-filter system). That has since cleared. That code didn’t fire the SES light, but would be apparent even after clearing codes with a scan tool. Many “smooth running cylinder” errors and “Cylinder x fuel injector ‘A’ offset learning at min limit” errors would come back and fire the SES light. After two bottles about a month ago and a third last week, the SES light has gone out without having to fire the parts cannon at the car again. I’ll post back here if that changes any time soon.So far I am happy with what this wonder additive has done for my car. Hope the results last.-Bob

As a college student, I was mortified to hear it would be 5500$ to fix the dpf and egr on a Jetta valued at 7000. I was looking up every fix I could for this check engine light (no dpf light, the code was code P2002 โdpf efficiency below minimum thresholdโ or something) and I tried driving my car hard, checking fuses, nothing worked. Finally I decide to try out a โbunkโ fuel treatment since thereโs no way that could work but itโs cheaper than a new filter. I chose this after seeing a review saying their CEL turned off after this and had to try. I put half a bottle into ~16 gallons and drove hard. Nothing. Drove hard for two more days. Nothing. Then I wake up and drive to work this morning, and it justโฆdisappears. Idk how or what is in that bottle but I can only say THANK YOU to whatever genius made this and a special thanks to the reviewer that convinced me to try.

2013 6.7L Ram 3500I had turbo issues that I have ignored for way too long. Within seven miles of adding this product, I saw an immediate increase in acceleration and responsiveness. Turbo was not creating pressure before, within 15 miles I was getting up to 15psi.Still have my codes showing up, and haven’t got the pressure any higher. At the same time, I’ve only gone through a couple of gallons of treated diesel. Going to hook up a trailer and pull it up some hills to put a load on the turbo and see if that accelerates this cleaning process.Cautiously optimistic!Will update after running 40 gallons of treated diesel.

Freightliner C2 Camper Bus. MBE 900 Diesel Motor. 190,000 miles – Had multiple EGR, DPF and turbo codes and very poor performance. Freightliner dealer repair shop quoted us over $3,500 to repair the “damaged” DPF, EGR and turbo systems. >>> After only one, $26 bottle of this product, and less than 100 miles of driving, all the codes are cleared and the entire fuel and emissions system is operating almost like new. The vehicle literally has 2x the power that it had (sticky injectors and stuck turbo probably), and runs waaay more quietly. As another customer stated; If a dealer/repair shop tells you that you need new DPF, EGR or turbo and a ton of code analysis, walkaway and buy a bottle of this stuff first! $3,500 of repairs just turned into $25. USAGE NOTES. We now also run Hot Shot FR3 friction modifier (oil treatment) in the engine oil, and a similar product in our AT2000 series transmission. The combo of using these products, as directed, will very likely get you great results. DO NOT over-concentrate this product in your fuel! Over-concentration in the fuel can cause damage to injectors and other fuel and emissions system components. Follow the instructions. ๐

I use the fuel additive once every other fill-up in my Ford F-250 super duty 4liter and have noticed that my truck has less knocking noise and responds wonderfully upon cold startup.
