    3-ethyl-4,4-diopropyloctance

    Is this correct?

    Just at a glance, you're missing an ethyl branch...

    3,5-diethyl-4,4-dipropyloctane

    No, remember the longest chain is the base, and it can be twisted round - so if you follow from the carbon in the top left of your drawing down to the branch, then go across one carbon, and down again, you've an eight carbon chain, making it an octane derivative. When you redraw it like that, the 3 carbons at the opposite end of the branch on the main chain at the left become a propyl group on carbon 5, and the other two carbons in the branch become an ethyl group at carbon 4, making it 4-ethyl,5-propyloctane. I've redrawn it, incase that doesn't make sense:
