Review: 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.
Review: Great product use as directed - This has been a great product, we have a fleet of box trucks. One truck was having frequent regen issues we started using this product and after a few uses we started seeing results. In my experience its not a one bottle fix all. but when used as directed it can prevent and help fix minor issues in the DPF system. I would recommend using this product before issues arise! But also a good option for minor DPF issues
