Fluorescent Oil Additive Method

  1. Clean the engine with a suitable cleaning fluid to remove all traces of oil.
  2. Drain the engine oil and refill with recommended oil, premixed with Gasoline Engine Oil Dye. Use a minimum 14.8 ml (0.5 ounce) to a maximum 29.6 ml (1 ounce) of fluorescent additive to all engines. If oil is not premixed, fluorescent additive must first be added to the crankcase.
  3. Run engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using a 12 Volt Master UV Diagnostic Inspection Kit. A clear bright yellow or orange area will identify leak. For extremely small leaks, several hours may be required for the leak to appear.
  4. As necessary, pressurize the main oil gallery system to locate leaks due to incorrectly sealed, loose or cocked plugs. If the flywheel bolts leak oil, look for sealer on the threads.
  5. Repair all leaks as necessary.
