What is your question?
The shop I go to says I need hi milage oil as apposed to the usual oil I get with a change... For which they charge an extra $10... Isn't simply using say 40w as opposed to 30w the same thing? greg

An oil can be regular or high millage regardless of viscosity(weight). Differents are in the additives.
If you don't have any oil leaks use a full synthetic lubricant like AMSOIL or mobil one. A full synthetic not a semi synthetic.
