Mobil 1 High Mileage 5W-30 is a full-synthetic motor oil blended for engines past 75,000 miles. Its seal conditioners and higher detergency target the problems older engines develop: oil burning, leaks and sludge. Mobil 1 rates it for up to 10,000 miles or one year between changes and backs it for turbocharged, supercharged and fuel-injected engines. Against conventional high-mileage oils it costs more but resists oxidation and breakdown longer; against Mobil 1's standard synthetic it adds seal conditioning and extra cleaning for worn engines. Owners rate it highly and mostly report quieter running and less oil consumption.
