Reliability, common problems and owner reviews for the Toyota Corolla 1.4 / 1.6 Dual VVT-i (1ZR-FE). Check this before you buy used.

The 1.6 ZR (1ZR-FE) is a smooth, chain-driven Toyota petrol that's fundamentally durable — the one caveat is oil consumption on early ZR-series builds (roughly 2007–2010), caused by the piston-ring design, which can be heavy on neglected examples. Toyota addressed it on later versions. Using the correct grade and checking oil regularly keeps it healthy; a serviced car with controlled consumption is a dependable engine.
