Engine oil sludge
Sludge is a semi-solid residue that can build up in an engine as the result of oil thickening or breakdown, most often the result of too-infrequent oil changes. High mileage oil can help remove engine sludge and reduce wear in older engines.
-
Engine oil consumption and leaks
Over time, an engine's seals can erode, causing engine oil to leak. Additives in certain high mileage oils can help protect worn seals and keep leaks from forming. Older vehicles tend to burn more oil and Mobil 1 High Mileage helps reduce oil loss caused by burn-off, particularly on cylinder walls due to leakage past the oil control ring.
-
General engine wear and tear
As engines age, they can increasingly wear out. Mobil 1 Extended Performance High Mileage and Mobil 1 High Mileage oils offer exceptional wear protection to help prevent wear and protect critical engine components – a claim supported by the industry-accepted Sequence IVA engine wear test.
