Dino or blended oil's after Auto-Rx is in your engine for 750 miles: change filter and oil. Visual results will be seen within 1500 miles of driving(this does not include sludged up engines which will show results in a few hundred miles). We are discussing dirty, contaminated, third party abrasive engine oil lubricated parts. Dino or blended oil's are 'recommended' for cleansing as they are cost effective and give faster results.
Synthetic oil's after Auto-Rx is in your engine 1500 miles: change filter and oil. Visual results will be seen between 2500 to 3000 miles of driving. Synthetic oil is not cost effective and results take more time.
