Dacia Sandero Fuel Tank Capacity: Complete Guide

Overview of the Fuel Tank Capacity

The Dacia Sandero’s fuel tank capacity varies depending on its generation, fuel type, and market specification. For most petrol-powered models produced between 2012 and 2022, the tank capacity is 50 litres (approximately 13.2 US gallons).

Bi-fuel versions, known as ECO-G models, feature two tanks: a 50-litre petrol tank and an additional 40-litre LPG tank. Some older or market-specific LPG-only versions may have smaller tanks rated around 32 litres, though these are less common.

Reasons for Capacity Variations

Several factors influence the differences in tank size across Sandero models:

1. Fuel system configuration – Petrol-only models use a single tank, while bi-fuel versions have an additional LPG tank, requiring design adjustments that can affect capacity.
2. Regional differences – Dacia adapts specifications to local standards, emissions regulations, and packaging needs.
3. Generation changes – Each Sandero generation introduced design revisions that slightly modified internal dimensions, often without major capacity changes.
4. Special editions – A few limited or LPG-only models carry smaller tanks (around 32 litres) tailored for specific regional requirements.

Fuel Tank Capacity by Generation

Generation II (2012 – 2020)

The second-generation Sandero (B52 platform) maintained a 50 litre fuel tank for both petrol and diesel engines. This generation includes popular versions like the 1.0 SCe, 0.9 TCe, and 1.5 dCi.

Generation III (2020 – Present)

The latest Sandero (DJF platform) also retains a 50 litre tank for petrol models. Bi-fuel (ECO-G) variants pair this with a 40 litre LPG tank, offering drivers extended range and reduced fuel costs.

Early and Special Versions

Certain early LPG-specific configurations (especially in niche European markets) show smaller capacities, such as 32 litres. These versions are rare and generally not part of the mainstream Dacia lineup.

Real-World Implications

Estimating Driving Range

A simple range estimate can be calculated using the average fuel consumption.
For example, with a 50 litre tank and an average consumption of 5.0 L/100 km:

Range ≈ (Tank Capacity / Consumption) × 100 = (50 / 5.0) × 100 = 1,000 km

This provides a theoretical maximum; real driving conditions—such as terrain, speed, and load—will slightly reduce this figure.

Efficient Refuelling Practices

• Always confirm whether your Sandero is petrol-only or bi-fuel before refuelling.
• Avoid overfilling beyond the recommended 50 litres to prevent pressure buildup and spillage.
• For bi-fuel models, remember that the petrol and LPG tanks operate independently; when one is empty, you can switch to the other for extended range.
• Regularly monitor both tanks to maintain optimal fuel efficiency and avoid running dry.

Key Takeaways

• Most Dacia Sandero petrol models feature a 50 litre tank.
• Bi-fuel ECO-G models combine a 50 litre petrol tank with a 40 litre LPG tank.
• 32 litre tanks are limited to older or market-specific versions.
• Knowing your exact tank size helps estimate range, plan refuelling, and maintain vehicle efficiency.
