Drivers in San Jose are paying $6 a gallon, $6.06 in Oakland, and $6.20 in San Francisco.
But a Shell station in San Francisco is charging almost a dollar more than that. Gas is going for $7.15 a gallon at a station at 4th and Bryant Streets.

Nationally, gas prices have hit a four-year high. The average is $4.30 a gallon, according to AAA.
All of this is due to inflation being driven up by the war with Iran.
A key inflation measure jumped in March as gas prices soared, the latest sign that the Iran war is pushing up the cost of living and delaying any interest rate cuts by the Federal Reserve.
The Commerce Department said Thursday an inflation gauge monitored by the Fed rose 0.7% in March from February, up slightly from the previous month. Compared with a year ago, prices rose 3.5%, the biggest increase in almost three years.
