Magic In A Bottle

Magic In A Bottle
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. :)

5.0 out of 5 stars Surprisingly Amazing!
Reviewed in Canada on February 27, 2022
My Truck was running like garbage! 2000 F-250 7.3L. Was throwing 9 engine codes, would barely start, usually wouldn't stay running, and if I tried to drive it anywhere it was an adventure, no power, could die anytime and strand you, a nightmare.

So I bought this Archoil Diesel Fuel system Cleaner and Archoil9100 Friction Modifier. Expecting to be disappointed but willing to take the risk before spending big money on repairs at a garage.

I dumped the products in, and tried to start the truck right away (block heater had been plugged in for hours). It was about -8C out; couldn't get the truck to run for more than 45 seconds. Did this 3 times.

The next day after leaving it plugged in over night, it starts under duress, but I manage to get the rpms up to 2000 and hold them there for about 5 mins. I let the truck come back to idle and leave it idling for 30 mins. Come back outside and it's still idling, good sign, sounds good too. Decide I'll drive it 1 km down the road and see how it drives to the gas station, I needed to fill it up after all, I hadn't followed the mix instructions on the fuel system Cleaner. I baby it down the road. Fill it up. Decide to give'r a rip on the way home and it runs awesome, decide I'll rip to the next town and get a coffee, truck pulls and cruises at 120 km/h easily.
2 weeks later ish ans still running great.

Also I wiped the engine codes and ran it for a few hundred kms and now only have 1 code that shows up.

Awesome product.
