Petrobras, as the company is known, said its current hedge position allowed it to delay for "some days" the price revision, without specifying the future readjustment.

On Thursday, Petrobras said it would readjust its diesel fuel price by 5.7 percent.

A massive truckers strike over diesel prices paralyzed Brazil almost a year ago and triggered the resignation of Petrobras Chief Executive Officer Pedro Parente.

In March, Petrobras modified its diesel pricing policy, saying prices would not be readjusted more than once every 15 days and reaffirmed its plans of not pricing the fuel below international parity.
