What goes wrong
The ACR50 Estima's 2.4 (2AZ-FE, shared with Camry/RAV4 of the era) is notorious for burning oil once past ~120,000 km due to piston ring design; Toyota acknowledged it and ran a warranty enhancement overseas, both long expired. Consumption of a litre per 1,000-2,000 km is common on tired examples, and running low on oil kills the engine. The proper fix is new pistons and rings — expensive on a people mover worth modest money.
What you would notice
- Blue smoke on start-up or hard acceleration
- Oil level dropping noticeably between services
- Spark plug fouling / misfire codes
- Rattly cold start if run low on oil
How to check it
Where to look. Engine under the front seats/front of cabin (check dipstick via engine access)
Pull the dipstick — low, black oil on a freshly listed car is a red flag.
Cold-start it and watch for blue smoke, then again after a hard acceleration on the test drive.
Ask directly how much oil it uses between services and whether top-up oil is carried in the car.
What it costs to put right
$3,000 to $5,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “How much oil does it use per 1,000 km?”
- “Has it ever had rings/pistons done or an engine swap?”
- “How frequently has the oil been changed?”
