Frequently asked questions
Which Mazda 2 engine is the most reliable?
1.5 SkyActiv-G (petrol) — Reliable verdict. The DJ Mazda 2's 1.5 SkyActiv-G is a high-compression (14:1) but naturally-aspirated, chain-driven petrol — no turbo to fail, genuinely reliable and frugal. The two things to know: it's direct-injected, so intake-valve carbon can build with age (worth an occasional clean to keep it crisp), and the high compression means it really does want the correct fuel and clean oil. There are no design weaknesses and the timing chain is rated for life. One of the safer modern supermini engines.
