Frequently Asked Questions
The octane rating of petrol is a measure of its resistance to knock, with higher octanes more resistant to knock. Petrol engines work by compressing air and fuel, then igniting the mixture with a spark. Certain engine conditions can cause all or part of the mixture to ignite on its own without the spark, creating what’s called “knock” in your engine. Fuels can be blended to meet different octane ratings at the refinery or fuel terminal.
The majority of today’s petrol vehicles are designed to run on regular octane fuel (95). However, using higher octane fuel than the minimum required can benefit fuel economy, power and acceleration even in vehicles calling for regular fuel. Engine design features like higher compression ratios and forced air induction (e.g. turbochargers or superchargers) can make engines more responsive to octane. The benefits achievable with higher octane depend not only on hardware design but also on the car’s calibration and the user’s driving style.

**Comparison is versus regular Esso Synergy Diesel. Esso Ethos+™ 25% Renewable Diesel contains a minimum of 25% renewable diesel. Choosing Esso Ethos+™ 25% Renewable Diesel instead of regular Esso Synergy Diesel results in 15% lower greenhouse gas emissions when comparing the emissions over the life cycle of each fuel. Fuels vary both in their total life cycle emissions (i.e. from production to use or “well to wheel”) and in how the emissions are distributed throughout that life cycle. The methodology for calculating life cycle emissions and emissions reduction follows that outlined in the Renewable Transport Fuel Obligations Order 2007 (SI 2007/3072) as amended (“RTFO”). Actual results may vary.
