Dacia Sandero TCe 90: Fuel, Efficiency & Upkeep Guide

The Dacia Sandero has carved out a niche in the UK market as a highly affordable and practical supermini, appealing to drivers who prioritise value and low running costs. A common query for prospective and current owners revolves around the TCe 90 engine: its fuel type, efficiency, and the best practices for its long-term care. Understanding these aspects is crucial for maximising your Sandero's performance and keeping maintenance expenses in check.

Understanding the TCe 90 Engine: Fuel Type Confirmed

For those wondering about the Dacia Sandero TCe 90 engine, rest assured: it is indeed a petrol engine. Dacia has deliberately focused on efficient petrol powertrains for the Sandero, shying away from more expensive hybrid or electric setups to maintain its competitive price point. This commitment to traditional internal combustion engines ensures that the Sandero remains an accessible option for many UK motorists.

Beyond the standard petrol variant, Dacia offers an intriguing alternative that sets the Sandero apart in the UK market: an LPG (Liquefied Petroleum Gas) version. This 'Bi-Fuel' option allows drivers the flexibility to switch seamlessly between a dedicated petrol tank and a secondary LPG tank. This innovative setup is a significant draw for those looking to further reduce their fuel expenditure, as LPG is typically cheaper per litre than petrol.

Dacia Sandero TCe 90: Fuel Economy and CO2 Emissions

One of the most appealing aspects of the Dacia Sandero, particularly with the TCe 90 engine, is its impressive fuel efficiency. While the older SCe petrol engine is no longer available new, its 53.3 miles per gallon (MPG) figure was mirrored by the current TCe 90 engine, showcasing consistent efficiency across the range. Both versions also boast CO2 emissions of around 120g/km, which is quite respectable for a supermini, contributing to lower Vehicle Excise Duty (VED) costs after the first year.

It's worth noting that the choice of gearbox can influence these figures. The manual transmission TCe 90 offers the best balance of efficiency and driving engagement. The automatic version, while convenient, typically sees a drop in fuel economy, with figures around 45.6 MPG and CO2 emissions rising to 129g/km. For those prioritising every drop of fuel, the manual is generally the recommended choice.

The Bi-Fuel Advantage: TCe 100 LPG Model

For used car buyers with efficiency at the top of their list, the TCe 100 Bi-Fuel model presents an even more compelling proposition. This variant comes equipped with both a standard 50-litre petrol tank and an additional 40-litre LPG tank, cleverly integrated into the spare wheel well. When running on LPG, the car can achieve around 42.2 MPG, and when switched back to petrol, it returns approximately 52.3 MPG. This dual-fuel capability provides an astonishing combined range of over 800 miles, significantly reducing the frequency of refuelling stops.

Furthermore, Dacia claims that running on LPG results in approximately 11% lower CO2 emissions compared to petrol, making it a more environmentally friendly option. The lower cost of LPG, often around 75p per litre, makes it highly attractive. However, it's crucial to remember that LPG availability at forecourts is not as widespread as petrol, so planning your journeys and checking local availability is essential.

Here's a quick comparison of the TCe 90 and TCe 100 Bi-Fuel models:

Delving into the 0.9 TCe Engine: Functionality and Common Traits

The 0.9 TCe engine, despite its relatively small capacity, is engineered for durability, particularly in urban driving conditions. A key aspect of its design is the use of a heavy-duty timing chain rather than a timing belt. Timing chains are generally designed to last the lifetime of the engine, offering greater longevity and reducing the need for costly periodic replacements that are common with timing belts. This design choice contributes to the engine's robust reputation.

However, like any engine, the 0.9 TCe has its quirks and potential areas for attention, especially as mileage accumulates. Some owners report that at high mileages, the engine may begin to burn oil. Oil consumption can be a normal characteristic for some engines, but excessive burning warrants investigation. It could indicate worn piston rings, valve seals, or other internal engine wear. Regular oil level checks between services become even more critical in such cases to prevent potential damage.

A more frequently highlighted 'weak point' for this engine family often relates not to the engine itself, but to its accompanying gearboxes. Owners sometimes describe the gearboxes as not being particularly precise, and there have been reports of bearings being susceptible to wear. Symptoms of worn gearbox bearings can include whining noises, difficulty engaging gears, or a general looseness in the gear stick. Addressing these issues promptly is important to prevent more significant transmission problems down the line.

Engine Oil for the TCe 90: Viscosity and Selection

Choosing the correct engine oil is paramount for the longevity and efficient operation of any modern engine, especially turbocharged units like the TCe 90. Engine oil viscosity, indicated by numbers like '0W-20', '5W-30', or '5W-40', refers to how thick the oil is at different temperatures. The 'W' stands for 'winter', indicating the oil's viscosity at low temperatures, while the second number represents its viscosity at operating temperature.

For instance, 0W-20 is a very low-viscosity oil, meaning it's thinner and flows more easily, particularly when cold. This can contribute to better fuel economy and quicker lubrication upon startup. Some discussions among owners have seen 0W-20 compared to the consistency of products like WD-40, purely as an illustration of its thinness, not its lubricating properties. It's crucial to understand that while 0W-20 is thin, it is specifically formulated with advanced additives to provide superior lubrication and protection for engines designed to use it. Conversely, 5W-30 or 5W-40 oils are thicker at operating temperatures, which might be preferred for certain engines or climates.

The exact oil specification for your TCe 90 engine will be detailed in your Dacia Sandero's owner's manual. It is vital to adhere to these manufacturer specifications. While dealerships might opt for oils that meet the manufacturer's authorised standards – which are often the most cost-effective options that still provide adequate protection – it doesn't necessarily mean they are the 'best' possible oil on the market in terms of premium additives or extended life. However, as long as the oil meets Dacia's recommended ACEA or API specifications, it will provide the necessary protection for your engine. Always check your manual or consult a Dacia specialist if you are unsure about the correct oil type for your specific vehicle.

Insurance, Warranty, and Servicing Your Dacia Sandero

Beyond the engine, other aspects of Dacia Sandero ownership contribute to its reputation for affordability:

• Insurance Groups: Thanks to its low-powered engines, straightforward design, and budget-friendly price, the Dacia Sandero typically falls into low insurance groups. For example, the manual Essential TCe 90 often sits in group 12, which can translate to significantly lower insurance premiums for many drivers.
• Warranty: Dacia provides a standard three-year and 60,000-mile warranty. While this is on par with some major manufacturers like Ford and Volkswagen, it's worth noting that it falls short of the more extensive warranties offered by rivals such as Kia and Hyundai, which often provide five or even seven years of coverage.
• Servicing: To help manage maintenance costs, Dacia offers servicing plans. These plans can be purchased upfront when you acquire the car or paid for through convenient monthly instalments, helping to spread the cost and budget for essential upkeep. Regular servicing according to Dacia's schedule is crucial for maintaining your warranty and ensuring the long-term health of your vehicle.

Essential Maintenance Tips for Your TCe 90

To ensure your Dacia Sandero TCe 90 continues to run efficiently and reliably, consider these maintenance tips:
