How Often Should You Change Mobil 1 Synthetic Oil?

by Keith Evans

Manufacturer Recommendations

Exxon Mobil, the manufacturer of Mobil 1 synthetic motor oil, recommends that users change the synthetic oil every 15,000 miles. For those who drive less than 15,000 miles in a year, the company recommends an oil change at least once a year to prevent the breakdown of oil viscosity. The company also points out that this interval will suffice even for those who frequently drive in heavy traffic.

Change More Frequently for Safety

Austin Davis, the mechanic behind the advice website Trust My Mechanic, recommends changing Mobil 1 synthetic oil more frequently than necessary. Davis recommends changing oil at least every 7,500 miles, as this frequency helps remove impurities that may have found their way into the oil. The more frequent changes, Davis points out, also give mechanics an opportunity to inspect the vehicle for other developing problems.

Bottom Line

Though the manufacturer recommends changing Mobil 1 synthetic oil every 15,000 miles, drivers who change the oil at 7,500 miles may stand a greater likelihood of catching problems before they develop.
