Product Description

Mobil Special™ Oils are formulated from high quality base stocks combined with modern performance additives to give your engine the protection and the performance you expect under a wide variety of operating conditions. Additionally, Mobil Special 5W-20, 5W-30* and 10W-30* are synthetic blend motor oils.

Mobil Special Oils are available in five multi-viscosity grades: SAE 5W-20, 5W-30*, 10W-30*, 10W-40, 20W-50.
