for instance, If you mixed two 0W-20 bottles of Mobil1 with three bottles of Amsoil 15W40 do you get the average of the two which would be 5W-35.
Does it work this way?

The Visc Calcs work great except for the "W" part. Kinda' hard to predict what'll happen at the very low end of the scale. But for summer use, you can ignore it.
To some extent the viscosity calculators will get you in the ballpark.
OTOH - your two example oils might or might not play together so perfectly. I wouldn't say such a blend would ruin an engine or anything - it's just that such oils are constructed so differently, that blending them may give you an oil that doesn't do it's designed job all that well - which would apply to the VII's and other additves as well as the finished 100°C viscosity.

Two full syns..some extent in the ballpark? Must be a real small ballpark...like whiffle ball sized.
Medium sized ballpark. Remember the given viscosities are "typical" and there are lot variations as well.
From a purely arithmetic perspective, your math is whacko. You'd end up with a 9W-32.
LOL....I'll take some of that 9w32 oil! Why do you want to mix those particular viscosities? Just wondering.
