I just love this product, it surely is worth the money a person pays. Truck is running smoother since I've put it in the fuel tank!

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.

Should have found this product years ago.
AR6400-D works well cleaning the soot from my 6.7 Cummins. Regens extended to over 1,000 mile intervals. Will continue to use every 5K miles. A MUST product for diesel engines new and old.
