15W-50

Mobil 1 15W-50 Motor Oil is formulated with Supers, an extra-high viscosity synthetic fluid, plus an 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.
