Banishing sludge

Your engine is a complex machine with hundreds of moving parts that operate under a wide range of temperatures and stressors. The oil you select needs to be equally capable of coping with these operating conditions to provide engine protection; otherwise, a thick sludge will form, causing the engine to develop problems. Oils with Antioxidants – Like Mobil – tend to repel sludge formation, and protect engines against wear, corrosion, and the build up of dirt and deposits.
