It Works! A DPF Miracle!
The DPF warning light came on in my 2014 VW Touareg TDI Lux and it was suggested that I run a tank with this product before I spend a fortune at the dealer. (To be detailed, my tank is 26 gallons, and this bottle will treat 40 gallons. So, I used 3/4 of the bottle and filled my tank. Added the remainder of the bottle and 10 more gallons of diesel when my tank was half empty.) Voila! The light went off within driving about 50 miles and has never come back on. That was a couple of years ago and I now run an Archoil tank about every 6-7 months, for good measure. The fine folks at Archoil recommend every 5,000 miles. I'm probably near that ballpark. Great stuff!

The directions are very simple
So far after using this, I seem like the truck is getting better fuel mileage, and it running a lot smoother

Works on gas turbo automobiles.
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.

I guess it works. My turbo is fine.
Since the turbo doesn’t seem to be caked up and everything is working good, I guess it helps

It works
This is a life saver. It was looking like I needed a new dpf filter. A few bottles of this product has my truck running like new and the filter stays empty. Amazing product
