Oil-Seals-Maintenance Plan

B.  Sludge Application.  First change your motor oil and filter. Add one full 12 oz bottle of Auto-Rx to your engine. 

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, changing your oil filter after approximately 1,250 miles. Change your oil and filter again, do not add Auto-Rx or any other additive. Drive an additional 3,000 miles, changing your oil filter after approximately 1,500 miles. 

Engines following the sludge application require a second treatment. Repeat the instructions outlined above.

We strongly recommend you continue to use non-synthetic oil and that you follow up your treatment by going on the Auto-Rx Maintenance Plan. This will ensure a CLEAN MOTOR and PREVENT FUTURE SLUDGE BUILD UP.

Maintenance Program

When you finish your Auto-Rx application these are just some of the results.You have restored your engines compression and also 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.
