“Saved Me From Spending 600 Dollars”

“I have a 2009 Volvo 780 with a Cummins ISX that was overdue for a particulate filter cleaning, and was regenerating every 50-100 miles. I put in the Diesel Extreme, and it restored the entire regeneration system. Truck is running noticeably better. It regens between 300-350 miles now, back where it’s supposed to be. It saved me from spending 600 dollars and shutting down the truck for 3 days to clean the filter.”
