Big warehouse discounter Costco has reportedly agreed to put in the equipment needed to ensure you get all the gas you pay for.

The advocacy group Consumer Watchdog says an announcement is expected any day now.

Consumer advocates have long argued that you get a little less gas when the temperature exceeds 60 degrees because gas expands and contracts with the temperature.

The agreement is reportedly part of a settlement stemming from two class action suits filed by truckers and drivers.
