Premium petrol without the price tag

The launch of Esso Synergy Supreme+ 99 Unleaded fuel comes with great winter savings for Porsche Club GB Esso Card™ fuel card holders

Listening to their customers is a priority for WEX Europe Services, and their team always enjoys meeting and gathering feedback from Porsche Club GB members.

Conversations at Club events made them aware that our members pay a great deal of attention to the fuel in their tank and that not everyone was comfortable with using 97-grade petrol in older Porsches.

Esso has launched a new fuel for drivers who want a higher octane for performance, and who believe in taking consistent care of their car: Esso Synergy Supreme+ 99 Unleaded*.

As well as having a higher octane level, which matches the UK’s highest octane premium fuel, Esso Synergy Supreme+ 99 Unleaded contains amongst other ingredients:

  • two detergents to scour your engine’s nooks and crannies and remove deposits
  • corrosion inhibitor to help prevent rust building up in the engine and fuel system
  • friction modifier to reduce friction and help your engine’s moving parts work more efficiently.
Ethanol content is another concern for many Porsche drivers.  We can confirm that Esso Synergy Supreme+ 99 fuel is ethanol free (apart from sites supplied in Devon, Cornwall, Teesside and Scotland).

Don’t be confused by the E5 grade label that service stations are legally obliged to carry on their pumps. The label indicates a fuel contains up to five per cent ethanol and in most parts of the country (see exceptions above) Esso Synergy Supreme+ 99 fuel is ethanol free.

To mark the launch of Esso’s new fuel, Wex Europe Services are offering a great saving on purchases using your Porsche Club GB Esso Card™ fuel card. From 1 December to 28 February, you will save:
  • 5p on every litre of Esso Synergy Supreme+ fuels (diesel and unleaded)
  • 2p on every litre of Esso Synergy standard fuels (diesel and unleaded).
The launch of Esso’s new fuel, along with these savings for Club members means that if you don’t already have a Porsche Club GB Esso Card™ fuel card, now is the perfect time to apply for one!

Offering a highly competitive discount off pump prices for all Esso Synergy fuels, the partnership between WEX Europe Services and the Club has provided significant savings for members. To apply for your card, visit, and for more information on Esso fuels, visit

What Esso says

Both the new Esso Synergy Supreme+ 99 Unleaded petrol and Esso Synergy Supreme+ Diesel have double detergent additives compared with Esso regular petrol and diesel fuels. These help to give engines a much deeper clean for better performance and fuel economy.

Esso Synergy Supreme+ 99 Unleaded includes molecules to reduce friction, helping moving parts to work more efficiently. Esso Synergy Supreme+ Diesel is designed to remove nasty deposits in the engine, helping to look after the engine and improve fuel economy.

New Esso Synergy Supreme+ 99 Unleaded is our highest octane fuel, increased from 97 to 99 octane (Esso Regular Unleaded is 95 octane). Higher octane can help reduce knocking-related performance losses in modern engines, and it can also help increase performance in engines designed for higher-octane fuels.
*Available at selected service stations (excludes North West initially).
