Using oils of any viscosity other than
those recommended could result in
engine damage.
Which is correct of course. But in this case, the grade is the same between a 5W-20 and a 0W-20.
Also, would anyone on here try and make a cogent technical argument that a heavier viscosity will result in engine damage?
