A 20-cent ‘mystery surcharge’ on gas? California lawmakers ask AG to find out why

Since at least 2015, Californians have been paying a “mystery surcharge” on gasoline that adds roughly 20 cents to each gallon — costing drivers more than $17 billion — and now a coalition of lawmakers is asking the attorney general to find out why.

A group of 19 legislators, including a dozen from the Bay Area, sent a letter Monday requesting the state’s Department of Justice to investigate the hidden charge identified in a 2017 report on the state’s high gasoline prices.
