Review: I thought it was going to be “snake oil” but the proof is undeniable. Truck idles, acellerstes and generally runs better. Have repurchased more.
Review: 1999 Volvo S70 GLT light pressure turbo, 138k. Check engine light P0234 code. Turbocharger Overboost condition. Most likely the waste gate on the turbo fouled with carbon. I am tired of working on the engine of this car. I thought I would try a bottle of Archoil cleaner. I put in the whole bottle in and filled the tank, 18 gallons. After a quarter of a tank burned the check engine light went away. And the car runs the best since I've had it. Smooth. More power and seems to be quieter too. Thumbs up. Good stuff. I'm sold.

## Questions & Answers

**Q: How Come u guys can’t get ur delivery days right  says next day then three days later I get my package**
A: just the way it is in your area of country and state...rare my orders come later but its usually a holiday..weather or construction

**Q: Have an 05 f350 with 6.0 power stroke. Should I use the full bottle in one tank or split it up between 2 fill ups?**
A: Been using this stuff for 4 years now 2007 Ford F-350 6.0 with 156K miles and my truck runs ten times better when I use this stuff and I also get a better gas mileage when towing. I’ve always used a whole bottle on a full tank a gas, but you can always try half and see there is any difference. I know it’s pretty pricey but the 6.0’s want to be pampered all the time it’s not even funny. If I don’t do oil service on every 3K miles that truck is like my kids it will start crying... lol.

**Q: can it be used on a isuzu yukon 2015 2.5l td twin turbo?**
A: Yes, AR6400-D is good for all diesel vehicles

**Q: Remove Water?**
A: Yes

*by T***Y on 27 February 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.
