"Yes it does, warming it up and the thinner/thicker oil I should be using.
So is 50W thicker than 30W? and 10-30W thicker than 5-30W?"

Yes and yes.

A 10w-30 oil is a 10 weight oil that will not thin any more than a SAE30w oil would at 100c.
A 5w-30 oil is a 5 weight oil (slightly thinner than the 10w oil) that will not thin any more than a SAE30w oil would at 100c.

The 5w-30 will flow better cold (at start up for instance)and in engines enginneered with fairly close tolerances.
