Guess this would cause a problem.

I would look at the actual curves, not a recommendation chart: http://www.viscopedia.com/viscosity-...es/engine-oil/

Plus, pour 5W at 30F or 20F, outside of the typical vis curves, it’s thick and slow. It just doesn’t make sense to use it at low temps. There are no benefits.
