📖Dacia Logan III (2020-2022): contemporary CMF-B foundations with LPG efficiency

Dacia Logan Phase 3 (2020-Présent)

Arriving in late 2020, the Logan III transitioned to the Renault-Nissan-Mitsubishi Alliance CMF-B platform, delivering marked improvements in chassis rigidity, acoustic insulation and active safety systems. Preserving its hallmark high-capacity 528-litre saloon silhouette, adherence to scheduled Dacia Logan maintenance ensures optimal longevity, particularly for examples engaged in intensive commercial, taxi or fleet service.

Engine configurations centre on the 1.0 SCe, the turbocharged 1.0 TCe turbo engine (offered with manual or a smooth CVT automatic gearbox), the highly popular factory ECO-G LPG bi-fuel system, and the 1.5 Blue dCi in select European markets. The bi-fuel ECO-G represents an outstanding balance of economy and performance, requiring disciplined servicing of both petrol and LPG gas injection filters.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Substantial leap in ride refinement, acoustic comfort and passive safety courtesy of the CMF-B platform.
  • The factory-fitted ECO-G 100 LPG system slashes running costs whilst providing over 1,000 km combined range.
  • Generous cabin legroom and a massive 528-litre boot retaining exceptional family and taxi utility.
  • Modern dashboard with smartphone integration, LED headlights and standard automatic emergency braking.

Chronic weak spots

Keep an eye on
  • 1.0 TCe and ECO-G (H4Dt): adhere to strict oil change schedules, inspect spark plugs and check turbo wastegate operation.
  • ECO-G LPG system: inspect gas pressure regulator, ensure seamless petrol-to-LPG changeover and renew dual gas filters.
  • CVT automatic gearbox: test take-off responsiveness, verify smooth ratio variations and ensure no slipping or whining.
  • Fleet and taxi wear: thoroughly check pedal rubbers, steering wheel rim, seat foam and suspension damper wear.
  • Boot sealing and tailgate alignment: inspect luggage compartment seals for water pooling around the spare wheel recess.

Critical deadlines

Do not miss
  • Engine oil and filter change every 15,000 km or 12 months using Renault RN17 specification fully synthetic oil.
  • LPG bi-fuel servicing: replace gaseous and liquid phase LPG filters every 30,000 km or 24 months.
  • Spark plug replacement every 30,000 km on ECO-G models (every 60,000 km on pure petrol TCe) to prevent ignition misfires.
  • CVT gearbox fluid inspection and brake fluid renewal every 60,000 km or 36 months.
