Mobil 1 15W-50 is recommended for high performance vehicles including turbocharged and supercharged engines where a thicker oil film is desired. Its high viscosity provides outstanding performance in high-revving, high-temperature conditions.
Mobil 1 15W-50 fully synthetic motor oil exceeds warranty requirements for gasoline engines where an API certified oil is specified. It meets:
API SM/SL
Requirements for Diesel Powered Vehicles where an API CF or API CD is recommended
Provides extra anti-wear additive for older vehicles
Mobil 1 15W-50 motor oil is formulated with SuperSyn, an extra-high viscosity synthetic fluid, plus extra anti-wear additive to provide extra protection for severe service applications such as towing, hauling and racing.
Mobil 1 15W-50 is also recommended for older valve train designs that may benefit from a higher level of anti-wear normally not required for newer generation vehicles. Mobil 1 15W-50 will also provide better anti-wear protection for higher valve spring tensions in certain racing engines.
