The cards below cover the main engines fitted to the Mazda 6 in the UK, including documented failure causes, variant production years, and typical rebuilt engine costs based on current UK market data.

Mazda 6 engine intelligence reference

R2BF

Production History

  • Mazda 6 GH 2.2 MZR-CD (2007-2012) - Hatchback, Saloon, Estate
  • Mazda 6 GH 2.2 MZR-CD facelift (2010-2012) - Sport, TS, TS2 trims
  • Early GJ transition units (2012-2013) - limited fitment

Known Failures

  • Timing chain stretch - tensioner wear causes chain jump at 80k-120k miles on high-mileage units.
  • DPF oil dilution - interrupted regeneration cycles cause diesel fuel contamination of engine oil.
  • Twin-turbo failure - sequential turbo setup prone to actuator and bearing wear on high-mileage examples.

Specs

Diesel · 2.2L · 125-180hp · Turbocharged

Replacement Cost

Typical UK rebuilt engine: £1,400-£3,800 (supply only)

PE (SkyActiv-G)

  • Mazda 6 GL 2.0 SkyActiv-G (2018-2024) - GT, GT Sport, GT Sport Nav trims
  • Estate/Tourer body styles across all generations

Known Failures

  • Carbon buildup on intake valves - direct injection design requires walnut blasting at higher mileage.
  • Timing chain guide wear - plastic guides can degrade on pre-2016 units with extended service intervals.
  • Water pump failure - external pump leaks common after 70k miles, requires timely replacement.

Specs

Petrol · 2.0L · 145-165hp · Naturally Aspirated

Is it worth replacing a Mazda 6 engine or should I scrap the car-

What is the most reliable Mazda 6 engine-

The 2.0L SkyActiv-G petrol (PE/PE-VPS) is generally the most reliable Mazda 6 engine, with fewer catastrophic failures than diesel units, though it requires regular intake valve cleaning.

  • SkyActiv-G petrol has fewer timing chain/DPF issues
  • Regular walnut blasting prevents carbon buildup problems
  • Diesel SkyActiv-D offers economy but higher failure risk
  • MZR petrol units are robust but need timing component attention
Compare rebuilt SkyActiv-G petrol engine prices for Mazda 6

What causes Mazda 6 diesel engines to fail-

Timing chain tensioner wear and DPF-related oil dilution are the two most common causes of Mazda 6 diesel engine failure, particularly on R2BF MZR-CD and early S8 SkyActiv-D units.

  • Timing chain rattling on startup signals tensioner wear
  • Oil level rising above max indicates DPF oil dilution
  • Short journeys accelerate DPF and oil contamination issues
  • Rebuilt engines include upgraded components addressing these weaknesses

Can I fit a different engine in my Mazda 6-

Engine swaps between same-generation Mazda 6 variants are possible with matching engine codes, but cross-generation or fuel-type swaps require extensive ECU and wiring modifications not recommended for standard replacements.

  • Same-generation same-fuel swaps are straightforward
  • ECU coding and immobiliser matching essential for any swap
  • Cross-fuel swaps (petrol to diesel) not cost-effective
  • Always verify engine code compatibility via registration lookup
Use our registration tool to find compatible Mazda 6 engines
