If you think you may have sludge in your engine, in our opinion, this is the best flush on the market!

Cleans the engine from the inside. Removes deposits from lubrication holes, oil screens, piston ring zone, etc. Reduces engine noise and oil consumption. Improves compression. Increases vehicle’s reliability. Allows the fresh oil to develop its full performance after an oil change.

Our recommendation for use:

  • Regular cleaning: Bring engine to operating temperature, add to engine, let idle for 10-15 minutes depending on degree of contamination. Drain oil while warm (allow plenty of time for all of it to drain). Then change the oil and filter (give the engine time to drain completely).
  • Heavy desludging: Change your oil using an inexpensive oil and filter, drive for ~50 miles, add to engine, let idle for 15 minutes. Drain oil while warm (allow plenty of time for all of it to drain). Then perform your final oil and filter change
