Dura Lube HL-40831-06-6PK Sludge Away Engine Cleaner, 32-Ounce, 6-Pack

Dura Lube Sludge Away cleans internal engine parts throughout the lift of an oil change. No need to immediately flush oil after using but can be used as a flush if needed. Repeated use helps break down and loosen sludge buildup, allowing it to run out with an oil change. It improves oil circulation and helps maintain oil viscosity.

• 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
