Felipe Massa is keen to see Interlagos privatised to secure the future of the Brazilian Grand Prix.
The future of the race in Sao Paulo is in doubt, with its position on the 2017 Formula One calendar still subject to confirmation.
Recent reports have suggested the recently elected mayor of Sao Paulo, Joao Doria, wants to privatise the track, which has hosted F1 since 1972.
"I'd like to talk to the mayor," said Massa, who will contest his last home race in Sao Paulo, his native city, this weekend before retiring.
"I want to hear his ideas before responding about something I don't know about. If the privatisation happens for the good of the circuit, I am completely in favour," he told Brazilian journalists in a pre-weekend dinner.
"If the privatisation is for something else, as happened to the track in Rio de Janeiro, then I am not in favour," Massa added.
Massa, 35, is also worried that there could be no Brazilians on the grid next year, with Felipe Nasr's future still up in the air..
"I hope that does not happen but there is a possibility," said Massa, "because Felipe has not signed a contract."
