Yes. Esso fuel meets UK legal quality standards (BS EN 228 for petrol, BS EN 590 for diesel) and includes a proprietary detergent additive package called Synergy. It is a reliable, quality fuel, though it typically costs more per litre than supermarket alternatives.

Yes, Esso fuel is good quality. Like all fuel sold in the UK, it must meet strict British and European standards, and Esso's standard grades include a proprietary additive package designed to clean engine components over time.

All UK Fuel Meets the Same Legal Standard

Legally regulated quality: Every litre of petrol and diesel sold in the UK must comply with British Standard BS EN 228 (petrol) and BS EN 590 (diesel). Esso fuel meets these requirements as a legal minimum. 2

Shared refinery origins: Much of the base fuel distributed across the UK, including to Esso stations, originates from the same refineries. The meaningful differences emerge in the additive packages added before delivery. 3

What Makes Esso Stand Out

Synergy additives: Esso standard petrol and diesel contain a detergent additive package marketed as Synergy, intended to help clean fuel injectors and inlet valves with regular use.

Esso Supreme premium grade: Esso also offers Supreme 99 high-octane petrol and Supreme+ diesel, which carry higher concentrations of performance additives aimed at drivers who want improved throttle response or engine cleanliness.

E10 compliance: Esso's standard unleaded is E10, meaning it contains up to 10% bioethanol as required by UK regulations since September 2021. Esso Supreme 99 remains E5 for vehicles incompatible with E10. 4

Is Esso Worth the Premium Over Supermarket Fuel?

Higher price than supermarkets: Esso stations typically charge more per litre than supermarket forecourts such as Asda or Tesco. For most everyday drivers, the base fuel quality is comparable. 1

Additive benefit depends on your driving: The cleaning additives in branded fuels like Esso offer the most benefit for high-mileage vehicles or those driven at sustained high loads. City drivers doing short trips are less likely to notice a difference.

Check prices before you fill up: Esso pump prices vary considerably between sites and regions. Use CheckFuelPrices to see live Esso prices alongside supermarket and independent stations near you before you pull in. 1
