no, synthetic motor oil lubricates better than regular oil. it produces less sludge and can go longer w/o being changed.
they say tests have shown that this fully true synthetic oil is superior to conventional oil in many respects, providing better engine protection, performance, and better flow in cold starts than petroleum-based motor oil (regular).
tone loc, synthetic oil is the best way to go but is a little more expensive. as for your question about brands i use castrol syntec (full synthetic) 10w-30. get a 5qt tub and you will have a little left over b/c your car takes 4.7qts.
