Tesco first started selling petrol in 1974. Tesco sells 95, 97, and 99 [[Octane rating|RON]] (a fuel developed by [[Greenergy]] of which Tesco is a shareholder) petrol from forecourts at most Superstore and Extra locations. Tesco recently diversified into [[biofuels]], offering petrol-bioethanol and diesel-biodiesel blends instead of pure petrol and diesel at its petrol stations, and now offering Greenergy 100% biodiesel at many shops in the southeast of the United Kingdom. In 1998, Tesco and [[Esso]] (part of [[ExxonMobil]]) formed a business alliance that included several petrol filling stations on lease from Esso, with Tesco operating the attached shops under its Express format. In turn, Esso operates the forecourts and sells fuel via the Tesco shop.<ref>{{cite news|title=Esso fuels Tesco's expansion|url=http://news.bbc.co.uk/1/hi/business/155524.stm|access-date=23 January 2015|work=BBC News|date=21 August 1998|archive-date=6 August 2023|archive-url=https://web.archive.org/web/20230806193636/http://news.bbc.co.uk/2/hi/business/155524.stm|url-status=live}}</ref> As of 2013, there were 200 joint Tesco Express/Esso sites in the UK.<ref>{{cite news |last1=Wood |first1=John |title=Roll-out of Tesco Clubcard reaches 800 Esso sites |url=http://www.forecourttrader.co.uk/news/archivestory.php/aid/7564/Roll-out_of_Tesco_Clubcard_reaches_800_Esso_sites.html |access-date=23 January 2015 |work=Forecourt Trader |date=20 September 2013 |archive-date=24 January 2015 |archive-url=https://web.archive.org/web/20150124012559/http://www.forecourttrader.co.uk/news/archivestory.php/aid/7564/Roll-out_of_Tesco_Clubcard_reaches_800_Esso_sites.html |url-status=live }}</ref>
