I would stick with it regardless of the cost difference. it increases fuel efficiency while decreasing emissions, friction and deposits, plus it doesn't burn off as quickly when hot. when cold (initial start-up) it flows faster to vital upper cams and valves. not only that, but it is much better suited to the long oil change intervals most DeLoreans experience (such as only changing the oil once a driving season).
