How much oil dose the ac system on a 1996 Chevy s-10 take?

The 1996 Chevy S-10 AC system's oil capacity isn't a fixed number readily available. It depends on the specific compressor and the size of the system's components. You should not attempt to add oil without professional guidance.

Instead of trying to guess the amount, consult your vehicle's repair manual or a qualified AC technician. They will have the correct specifications and procedures for servicing your system, including the proper amount of oil to add if needed. Adding too much or too little oil can severely damage your AC compressor.
