FAQs

 

Mobil 1 15W‐50 is a higher viscosity oil that delivers a thick oil film for protection of high‐performance engines. Mobil 1 15W‐50 can be used and is recommended for both street and track use; however, Mobil 1 Racing™ oils are not recommended for general street use where vehicles use catalytic exhaust converters. Mobil 1 Racing™ 0W‐30 and Mobil 1 Racing™ 0W‐50 are lower viscosity oils designed to protect the engine under high output conditions in high operating temperatures. Additionally, Mobil 1 Racing oils offer boosted levels of anti‐wear protection (nominal zinc level of 1,850 ppm) for extra engine protection in highly loaded flat tappet engine designs like those used in the NASCAR® Sprint Cup series.

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.
