You don't say which engine powers your 2015 Chrysler 200, but according to the owner's manual I found here http://cdn.dealereprocess.com/cdn/servicemanuals/chrysler/2015-200.pdf your vehicle should use either 0W-20 or 5W-20.
From your owner's manual:
"MOPARÂ® SAE 0W-20 engine oil or equivalent PennzoilÂ®
or Shell HelixÂ® is recommended for all operating temperatures.
This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also states the recommended engine oil viscosity
grade for your engine.
Lubricants which do not have both the engine oil certification
mark and the correct SAE viscosity grade number
should not be used.
Engine Oil Viscosity â€" 3.6L Engine
MOPARÂ® SAE 5W-20 engine oil approved to Chrysler
Material Standard MS-6395 such as PennzoilÂ®, Shell
HelixÂ® or equivalent is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the â€śEngine Compartmentâ€ť
illustration in this section.
NOTE: MOPARÂ® SAE 5W-30 engine oil approved to
Chrysler Material Standard MS-6395 such as PennzoilÂ®,
Shell HelixÂ® or equivalent may be used when SAE 5W-20
engine oil meeting MS-6395 is not available."
