Oil-Seals-Maintenance Plan

D.  Seal Leaks Application.  First change your motor oil and filter.  Add 2 ounces of Auto-Rx® for each quart of oil your engine holds.

Auto-Rx® works best with conventional (non-synthetic) motor oil.  If you feel you must use a synthetic motor oil we recommend using a Group III oil to avoid competing chemistries. 

Drive 2,500 miles, then change your oil and filter again, but do not add Auto-Rx or any other additive.  It is important that you use non-synthetic oil during this phase. Drive an additional 3,000 miles, then change your oil and filter again. 

Vehicles with over 100,000 miles require a second application.  Repeat the instructions outlined above.

Leak should stop within the next 3,000 miles.  Application is finished when leak stops.  Returning to synthetic oil may cause the leak to return. 

We recommend that you follow up your treatment by going on the Auto-Rx® Maintenance Plan. Do not begin a Auto-Rx ®Maintenance Plan until rotating seal leak has stopped.

Maintenance Program

t is strongly recommended that you begin an Auto-Rx® Maintenance Plan following your particular Auto-rx® application.

When you finish the Auto-Rx application these are just some of the results:

  • Restored your engines compression
  • Restored the efficiency of your engines combustion.
  • The maintenance program keeps the chemistry and benefits just like they were after application.
  • You never have to clean your engine again.


Add 3oz of Auto-rx to every oil change.

For sludged engines add 4oz to every oil change.
