Flushing oil concentrate didn't work on my Hyundai Santa Fe 2007 Diesel driven 290000km. I flushed the engine oil for a total of 3 times and each time, new 5L oil was added into the engine followed by 85 mL of the Flushing oil concentrate. The car engine was run for 30 min each time while the car was in idle. The drained oil was still black and full of carbon. I bought this Flushing oil concentrate (250 mL) for $103 with discounted price but proved to be ineffective in my case. At the end, I regretted that I should have bought engine flush liquid from car autos (e.g. Supercheap, Autobarn or Repco).
