My 2014 Sport with 2.4L factory service manual only has this table:

A/C Compressor​
Denso 10SRE18 fixed displacement - All 2.2L Diesel engine models
Denso 6SEU16 variable displacement - All Gasoline engine models​
ND-8 PAG oil​
A/C Clutch Air Gap (2.2L Diesel engine models)0.35 - 0.60 mm (0.014 - 0.024 in.)
A/C Clutch Coil Draw (2.2L Diesel engine models)3.2 - 3.3 amps@ 12V ± 0.5V @ 21° C (70° F)
A/C Clutch Coil Resistance (2.2L Diesel engine models)3.6 ± 0.2 ohmsWhen measured across coil lead connector
Freeze-up Control​
Evaporator temperature sensor​
Input to A/C-heater control, HVAC housing mounted - sets compressor to destroke/disengage 2° C (36° F) below evaporator target temperature (minimum 5° C (41° F)) and activates/engages compressor when within 1° C (34° F) of evaporator target temperature​
High psi Control
A/C pressure transducer​
Input to PCM/ECM, discharge line mounted - sets compressor to destroke/disengage above 3130 kPa (454 psi) and below 200 kPa (29 psi)​
Low psi Control​
A/C pressure transducer
Input to PCM/ECM, discharge line mounted - sets compressor to destroke/disengage below 200 kPa (29 psi), activates/engages compressor above 234 -262 kPa (34 - 38 psi)​
R-134a Refrigerant Charge Capacity595 g (1.31 lbs.)Also see A/C Underhood Specification Label located in the engine compartment
 
Found it!!!!!!!!!! One of my more challenging Google searches!

Go to page 79 of this pdf below. Looks like 3.4 oz. of PAG oil - this assumes a totally dry system? Other sites suggest adjusting the amount refilled if you have oil left over in the system. I always tell people to confirm their own information.
