The oil capacity for a 1996 Jeep Wrangler depends on the engine. There were several engines offered that year. You'll need to check your owner's manual or a reliable source like a parts website using your Vehicle Identification Number (VIN) to determine the exact oil capacity for *your* specific Wrangler.
Generally, it's between 4-5 quarts. However, don't rely on this general number; always check your owner's manual for the precise amount.
