Sludge Application
Do you have a "sludgemobile"? Read more>>
| SLUDGE CLEANING PHASE: | |
| FOR BEST RESULTS, USE ONLY CONVENTIONAL OR ONE OF THE APPROVED SYNTHETIC OILS TO REMOVE SLUDGE. Most synthetic oils have a complex additive package that holds oil to metal, which also applies to sludge and therefore hinders the safe removal of sludge. Warning: The use of any oil not approved for Auto-Rx® will cause the sludge to return as though it had never been removed! Approved synthetic oils here>> | |
| STEP 1 | Pour in Auto-Rx®: Add Auto-Rx® at a ratio of 3 ounces per quart of oil to the crankcase with a fresh oil change and filter. If you recently had an oil change and are using conventional or an approved synthetic oil, go ahead and add Auto-Rx® to the oil already in the crankcase. |
| STEP 2 | Blend Auto-Rx® with the Oil: Run the motor for 5 minutes or so to blend the Auto-Rx® into the host motor oil. For best results, run with conventional oil or an approved synthetic oil. |
| STEP 3 | Drive 2,500 Miles: Over time, drive the vehicle 2,500 miles with normal driving habits. About halfway through the first cleaning cycle at 1200-1300 miles, change the oil filter only (may not be necessary in the second cleaning phase). See reason below. If necessary, top off the oil (but do not add Auto-Rx® or other additives); then finish the remaining 1200-1300 miles in the cleaning phase. This completes the first cleaning phase. |
| RINSING PHASE: | |
| STEP 4 | Change Oil and Filter: Drain the oil and refill with fresh oil and a new filter. Again, use conventional oil or an approved synthetic oil. |
| STEP 5 | Drive 3,000 Miles: Over time, drive another 3,000 miles; then change the oil and filter again. This completes the rinsing phase. |
| STEP 6 | Congratulations! Your first sludge application is finished. For heavy sludge, repeat STEPS 1 THROUGH 5 to complete the second sludge removal application. After cleaning, add 2-3 ounces of Auto-Rx® with each oil change to keep the engine clean. Use with any oil after the cleaning process is completed. |
NOTE—Reason to change filter at halfway mark: For heavy sludge, we recommend changing out the filter at the 1200-1300 mile mark. The reason for this is that the oil filter can become loaded before completing the 2500 miles of running. In that case, a fully loaded filter will go into the bypass mode whereby the filter is no longer capturing the contaminants and the contamination is circulating throughout the oiling system. This is somewhat counterproductive and undesirable. Auto-Rx works best with maximum oil flow throughout the oiling system, so oil restriction due to a completely filled oil filter is counterproductive.
Heavy sludge applications require a second treatment. In most cases during the second application of Auto-Rx, the need for filter changes at the halfway mark are not necessary.
To maintain a clean engine after an initial cleaning and rinsing, add just 2-3 ounces of Auto-Rx® with each oil change. This will provide additional cleaning over the long haul and will prevent having to clean the engine again down the road.
