The 2ZR-FAE Valvematic can develop oil consumption above 80,000 miles, particularly on cars with stretched oil-change intervals. Toyota's recommended interval with synthetic is 10,000 miles. The newer 2.0L M20A-FKS (SE/XSE/XLE) has a better oil consumption record in owner reports to date.
Check the oil level cold on the dipstick before the test drive. If the level is below midpoint on a mid-interval 1.8L car, the engine is consuming. Ask for oil-change records and confirm intervals were not stretched beyond 10,000 miles.
Est. cost: $0 if managed / $1,500–$3,000 piston ring service if chronic
