Frequently asked questions
Which Mazda 2 engine is the most reliable?
1.3 / 1.5 MZR (petrol) — Reliable verdict. The Z-series petrols (1.3 ZJ / 1.5 ZY) in the DE Mazda 2 are simple, timing-chain-driven, dependable engines — light, willing and good for high mileage on basic servicing.

No design vices — a genuinely low-worry supermini engine.
