Does your 200 have an oil pressure gauge? You can cross reference to
that. Also, there are indeed two oil pressure switches, they both should
be checked. Finally, if you check your owner's manual, you are probably
running oil that is too thin for summer conditions, personnally, I run
Mobil 1 15W-50 once the temperature stays above freezing, 10W-30 in the
winter. Also, with the turbo, I'd strongly recommend running synthetic
oil, which is less prone to coking in the turbo than conventional oils.
