Sludge 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 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. If necessary, top off oil (no Auto-Rx®), and finish cleaning application.
Rinse Mode: Drive an additional 3,000 miles with clean oil only (no Auto-Rx®), and change your oil filter after approximately 1,500 miles. If necessary, top off oil (no Auto-Rx®) and finish rinse mode. We strongly recommend changing the filter due to the possibilty of sludge buildup in the oil filter.
Engines following the sludge application require a second treatment. Repeat the instructions outlined above.
We strongly recommend that you follow-up your Auto-Rx® treatment by starting on the Auto-Rx® maintenance plan with regular oil change intervals. This will ensure you keep a clean motor by preventing future sludge buildup.
