Oil consumption on other Wrangler years
No other Wrangler model year has enough reports of oil consumption for a sheet of its own. See every Wrangler year.
What this problem usually is
Two different complaints land here. The more common one is an engine that uses oil: owners add a quart between changes, get a low-oil warning, or are told by the dealer that the rate is normal. The other is the opposite, where the oil level climbs and the oil smells of gasoline. Both deserve a proper test, and both are easier to argue with records in hand.
What got replaced
Owners who name the part that was replaced mention the piston rings (11 reports).

Should you keep driving it?
This page can't tell you that. 0 of 42 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
