BOSTON (CBS13) – The average price for a gallon of gas is lowest on Tuesday in California, according to analysis done by GasBuddy.

The gas tracking company looked at nationwide data from January to March and determined the best and worst days to buy, and the days with the shortest and longest lines.

  • Tuesday is best day to buy in CA
  • Monday is best day to buy in US
  • Friday is worst day to buy in CA and US
  • Sunday is least busy day
  • Friday is busiest day

Nationwide, Mondays and Sundays are the best-priced days- with 21 states registering the lowest-prices of the week. Tuesday is considered a good “top off” day- meaning it’s good to buy, but not necessarily the best. “Though there is variation in daily gas prices across different states, the consensus is that the earlier motorists fill-up during the week, the better,” says Patrick DeHaan, head of petroleum analysis at GasBuddy.
