We stand behind our products

Please read our Mobil 1™ limited warranty. Always check your owner’s manual for the manufacturer’s recommended oil viscosity grade, API service classification and any builder approval. You can also refer to the Mobil 1™ Product Guide for a quick look at key manufacturer approvals and info on the zinc and phosphorus levels in Mobil 1 FS X2 5W-50 motor oil.

If your vehicle is covered by a warranty, follow the vehicle’s oil-life sensor or the oil-change interval recommended in your owner’s manual. Proper maintenance practices, including frequently checking the oil level to ensure the appropriate amount of oil is present, are required to ensure effective performance.


Oil change intervals can be as short as 3,000 miles or as long as 20,000 miles on some new cars. We recommend that you follow the oil and filter change frequencies shown in your owner's manual, especially during the warranty period. With the high‐performance reserves of Mobil 1, you can have the confidence to go the full mileage or time frame recommended by the vehicle manufacturer. Mobil 1 is especially suitable for the latest vehicles with extended drain intervals or vehicles with oil monitoring systems that vary oil drain intervals. To fulfill the requirements of the Mobil 1 limited warranty, Mobil 1 motor oil must be changed at least every 10,000 miles or your vehicle’s OEM recommended oil change interval, whichever is longer.

With the exception of the Mazda rotary engine (Mazda does not recommend any synthetic oils), Mobil 1 will not void new‐car warranties where an American Petroleum Institute (API) certified oil is recommended. Mobil 1 meets or exceeds API and International Lubricant Standardization and Approval Committee (ILSAC) motor oil service requirements of all new‐car manufacturers, both import and domestic. If in doubt, always check your vehicle owner's manual or contact the vehicle manufacturer.

Many kinds of driving conditions qualify your vehicle for severe service oil change intervals, and Mobil 1 is ideal for this service. Severe service conditions can include, among other things:

  • Trips of less than 10 miles
  • Driving in cold weather
  • Idling for extended periods
  • Stop‐and‐go traffic
  • Pulling trailers/carrying heavy loads
  • Driving in dusty conditions

Under both normal and severe service conditions, Mobil 1 is engineered to provide performance reserves in the areas of sludge prevention, piston cleanliness, wear protection and high‐temperature durability.
