Is Tesco fuel good?
CheckFuelPrices Editorial
Expert Written • 4 industry sources
Yes, Tesco fuel is good quality and perfectly safe for your car. All petrol and diesel sold in the UK — including at Tesco — must meet the same British and European standards (BS EN 228 for petrol, BS EN 590 for diesel), so there is no meaningful quality gap between Tesco and a premium branded station.
Tesco Fuel Meets UK Legal Standards
Legally regulated quality:
Every litre sold at Tesco must comply with UK fuel quality regulations. The base fuel is refined to the same specification as branded fuels and often originates from the same refineries.
2
Standard E10 petrol:
Tesco's unleaded petrol is E10, containing up to 10% bioethanol — the same grade mandated across all UK forecourts since September 2021.
3
No evidence of engine harm:
There is no credible evidence that Tesco fuel causes engine damage or accelerated wear compared to branded alternatives.

How Tesco Fuel Differs From Branded Fuels
Additive packages:
Branded fuels such as Shell V-Power or BP Ultimate include higher concentrations of proprietary cleaning additives. Tesco fuel meets the legal minimum additive requirement, which is sufficient for most everyday vehicles.
2
No premium grades:
Tesco does not sell premium or high-octane fuel variants, so if your vehicle requires or benefits from 97–99 RON fuel, you would need to visit a branded station.
Suitable for the vast majority of drivers:
For standard petrol and diesel engines driven in normal conditions, the difference in additive concentration has no measurable real-world impact.
The Price Advantage of Tesco Fuel
Consistently cheaper per litre:
Tesco regularly prices fuel 3–8p per litre below branded stations, using it as a footfall driver for their superstore business.

Prices vary by location:
Tesco forecourt prices differ between stores and can change multiple times per day, so the cheapest nearby Tesco is not always obvious.
