2.5L four-cylinder oil consumption (owner-reported)moderate
Several 2016 owners report the 2.5L using roughly a quart every 1,000 miles or arriving at a service low by a couple of quarts, and the community problem videos tie it to piston rings and the PCV valve on this engine family. Toyota's oil-consumption program covers the older 2AZ engine (2007–2011), not the 2AR-FE here, so there's no coverage to fall back on — treat it as a screening item. Pull the dipstick yourself, ask how often the seller tops up, and factor a quart-in-the-trunk habit into a high-mileage example.
