Help to fill up with less impact

We’re constantly looking for innovative ways to improve fuel economy and reduce emissions. Here’s a small example of what we’re doing to be part of the solution.

Developing lower emission fuels

New Synergy petrol gives you more efficiency for your journey

Engine technology is constantly evolving. Modern car engines are designed to use fuels more efficiently, improving their fuel economy. For these systems to work effectively they need to be kept clean. And as engine technology changes, so has our fuel technology. Our new and improved Synergy fuels contain three detergent additives which have been specially formulated to work in the tougher conditions of modern gasoline direct injection (or GDI) engines. Working together to remove deposits, and protect your engine from build up. Cleaner engine parts can lead to better fuel economy, helping you save fuel.

Developing lower emission fuels

If you are interested, here are some ways ExxonMobil’s technical teams around the globe are working to develop lower emission fuels.

A number of exciting lower emission fuels opportunities are being developed, including a project to produce renewable diesel in Canada2.
ExxonMobil's research teams, working with Toyota, have been busy exploring innovative formulas for lower-emission fuels to power today’s and tomorrow's vehicles, with the potential to reduce lifecycle GHG emissions by up to 75% compared to conventional fuels available today3. To demonstrate that these fuels are technically feasible, Toyota has been testing ExxonMobil's research fuels in Toyota's advanced engines and vehicles. The tests confirm that these fuels can be compatible with both today's vehicles and have the potential to use existing fueling infrastructure.

Here’s a thought:

  • Woman planning fuel stops on her mobile phone.

    Plan your fill ups

    Rather than waiting until the red light comes on – when you may need to drive out of your way to fill up – call in at your next petrol station when you’re starting to run low.

    The more you can plan your fuel stops in advance, the more efficient you can make them. That could mean making them fit better into your daily routine, or finding the quietest time to fill up – but don’t make a special journey if you can help it.

    Collect Nectar points

    Saving fuel saves you money. But if you do have to top up, buy your fuel from Esso and collect Nectar points. You can then swap these and save 5p a litre on your next fill4.

1 Comparison is versus regular Esso Synergy Diesel. Esso Supreme 25% Renewable Diesel contains a minimum of 25% renewable diesel. Choosing Esso Supreme 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”). For more details about the product and full details of the calculation including assumptions and emission factors visit  ESSO and the Esso Logo are trademarks of ExxonMobil Corporation or one of its subsidiaries.
2 Production facility expected to be completed in 2025. Anticipated production of up to 6MB/year of renewable diesel.  As reference, ExxonMobil global refining throughout is 4.1MB/day (Source:  Strathcona: The road to renewable fuel | ExxonMobil; EM Annual Report 2023)
3 Products not available as part of our fuel product offering. Reductions in Carbon Intensity (CI) estimates are based on the lifecycle greenhouse gas emission of the fuels tested at Toyota’s Research Center, compared to petroleum gasoline. Estimated CI values are based on either GREET 2021 estimates, or feedstock Proof of Sustainability documents. Actual results may vary. America’s future: ExxonMobil & Toyota | ExxonMobil
