It all depends on the engine and application. OEM's that demand more performance out of lubricants set specification targets that have to be met. Most of those can only be met with synthetic base oils.
If your manual doesn't call for synthetic, then no you don't need one. *However, some engines such as the Honda V6's that run hot could definitely benefit from a good synthetic. Mobil 1 can handle temperatures up to 500F.
Oils like Mobil 1 EP and Amsoil do have additives and base oils that are designed for longer oil change intervals. They are more expensive as a result, but you generally get what you pay for.
The savings are small compared to much other expensive variables like fuel efficiency and other general maintenance items.
If you want to look at it from a completely economical standpoint, I think the value of the blends from PZ and Valvoline are great. Mobil 1 full synthetic at WM is still tough to beat for what you're getting. SOPUS products too.
