Fuel station operators on Friday announced they will shut down June 6-8 to protest against the government's plans to deregulate their sector.
In February the operators called a total of 14 days of strikes but suspended the action after a two-day shutdown in order to open with with the government.
Last month the operators returned to the warpath after failing to win concessions from the government and the prospect of the reforms clearing parliament before the summer.
The operators are furious at plans to allow shopping centres and supermarkets to sell gasoline, the abolition of rules establishing minimum distances between stations and the extension of opening hours.
They say the changes could force them out of business.
The new norms are contained in a liberalisation bill drawn up by Industry Minister Pierluigi Bersani.
The bill is linked to previous deregulation packages aimed at ending anti-competitive practices in several protected fields which have already been approved.
Consumer groups have hailed the reforms, saying they will save households from 550 to 1,330 euros per year.
The groups criticised the fuel station operators on Thursday saying: "Instead of calling ridiculous strikes, they should focus on improving their competitiveness which would benefit everyone".
