Cleaner & Cooler Cummins

Clean oil on dipstick — “…the oil on the dipstick stayed really clean – never seen that before…“

“I used the Flushing Oil Concentrate in my 1997 Dodge Ram Cummins. Amazing result! The oil on the dipstick stayed really clean – never seen that before. And it runs a lot cooler now, especially when towing the 5th wheel. Many thanks!”
