High end synthetics are actually cheaper if you run the recommended extended oil change intervals. Amsoil has an oil with a maximum change interval of 35,000 miles (although I wouldn't go that far due to consumption and such). I do use it in my delivery van and change my oil every 20,000 miles. It is now up to 353,000 miles, ~175,000 of which was on Amsoil.
