Gosh, I was just using the chart as a visual indicator that 5Wxx and 10Wxx cover about 95% of the same ground above 32*F, and also why I asked why he "needed" a 5W in summer. Whether or not the illustrated ranges are 100% correct, it was a simple answer to a simple question.
5Wxx and 10Wxx of the same grade are functionally identical as far as viscosity is concerned in typical North American temperatures during the summer season. Better?
Ok, I see your point. But reading that chart can lead someone to think if they're running 0W16 in their new Toyota and temps reach 80F or higher in the summer they'll grenade their engine. Unfortunately a lot of people reading sites like this know just enough to get into trouble, or take what they read as Gospel.
