Reduces sludge buildup and prevents oil coking.
For repeated use, change oil every 3,000 miles on most passenger vehicles by substituting 1 quart of motor oil with Dura Lube Sludge Away. Continue using until sludge appears to be reducing. Check oil pan to review sludge consistency on discarded oil.
For more severe sludge build up, change the oil and add Sludge Away engine product every 1,000 miles.
Repeat application as needed until performance and oil color returns to normal.
oil color should be amber to a dark brown, not black.
Sludge Away engine product works with all types of motor oils including high mileage and synthetics.
