I was reading the owners manual and I thought this might be helpful
to end the debate about what fuel is needed for our 2.4s

If the vehicle has the 2.4L L4 engine (VIN Code V)
or the 2.0L L4 engine (VIN Code M), use premium
unleaded gasoline with a posted octane rating of
91 or higher. You can also use regular unleaded
gasoline rated at 87 octane or higher, but the vehicle's
acceleration could be slightly reduced, and a slight
audible knocking noise, commonly referred to as spark
knock, might be heard. If the octane is less than 87, you
might notice a heavy knocking noise when you drive.
If this occurs, use a gasoline rated at 87 octane or
higher as soon as possible. Otherwise, you could
damage the engine. If heavy knocking is heard when
using gasoline rated at 87 octane or higher, the engine
needs service
