Sunshine, I would look to other causes before the oil pump. Numbers of
others have now told me that they rarely fail. More likely, if you
indeed do have low oil pressure (try to find every reason that you might
be getting the signal despite adequate oil pressure first), its unlikely
to be due to the pump -- but rather something more serious, internal to
the engine. Almost as good a temporary patch on that as a new pump is
heavier oil, at least while the weather is warm. Single weight oil
holds its viscosity better than does multi-vis, too. If your vehicle is
running hotter than it should, multi-vis oil may be thinning too much as
the engine reaches the higher temperature.
Dave Mc (no expert, but have recently gone through some of this oil
pressure business. Mine wa a combination of coolant system problems and
the wrong oil, plus a monitoring system that was out of kilter)
