Esso has announced the launch of its first 99 Octane fuel – Synergy Supreme+ 99. The new premium fuel will be available on forecourts nationwide from October 14, with the exception of 140 sites in the north west, which won’t have supply until next year. The high-spec fuel fills a gap at the top end of Esso’s forecourt fuel line-up and gives retailers a product to challenge Shell’s V-Power unleaded. Currently the highest-spec Esso fuel available to the motorist is 97 RON.
