Petrolul signed a one-year kit deal with American sportswear company Nike, after the association with Puma came to an end.

[2] Gevaro Nepomuceno, Patrick N'Koyi, George Mareș, Jean-Alain Fanchone, Alberto Cobrea, Mirel Bolboașă, Andrei Peteleu and Mourad Satli were transferred to Petrolul.

[6] However, losing both of the play-off legs against Dinamo Zagreb of Croatia, Petrolul yet again missed the chance of advancing to the group stage.

Cosmin Contra, Petrolul's coach from October 2012 to March 2014, said that the signings of Adrian Mutu and Ianis Zicu (both joined in January 2014) were a "failure".

[16] On 25 November, president Daniel Capră, general director Marius Bucuroiu and five other persons faced preventive detention for 24 hours, being suspected of tax evasion and money laundering.

[19] During the winter transfer window, five footballers left Petrolul, including important ones like Juan Albín and Soni Mustivar.

[20] However, among others, Mircea Rednic convinced 31-year-old striker Mohamed Tchité, who spent most of his professional career in Belgium, with Standard Liége, Anderlecht and Club Brugge, and in Spain with Racing de Santander, to be part of the team until the end of the season at the least.

[21] Mohamed Tchité made his début on 5 March in the first leg of the Romanian Cup semi-final against rivals Steaua București, scoring his team's only goal in a 1–1 draw.

[22] On 3 April, Petrolul missed the qualification to the Cupa României final for the second year in a row, losing the semi-final second leg against Steaua at Arena Națională.
