As I understand it, Extended Performance oils are long drain oils. Now, to further muddy the waters so to speak, there is also Valvoline Extended Protection. Is this also an extended drain motor oil? There is also Quaker State Ultimate Protection that advertises 20K mile oil changes, along with Supertech. Then there is Amsoil signature that advertises 25K mile changes, but it's double the price, if not more. Is it really worth the price for an extra five thousand miles?
