Switching Oil Viscosity due to Product Availability
Based on availability of particular viscosities of your product, is it all right to switch from one weight to another (i.e., 5W-20 then 0W-20)?
-- William Stiener, Crown Point, IN
We specifically formulated Mobil 1 0W-20 Advanced Fuel Economy to provide the same high-temperature protection as Mobil 1 5W-20.  As always, please consult your owner's manual for the appropriate viscosity grade for your vehicle.
