In brief
A viral TikTok trend has drivers checking if gas stations short them fuel, but the test is flawed and dangerous. Milk jugs aren't designed to measure fuel accurately, and putting gasoline in them creates a serious fire hazard. Report suspected pump problems to your state's weights and measures office instead…
The viral milk jug test
Drivers are pumping what the dispenser says is one gallon into empty milk jugs to check if gas stations are short-changing them on fuel.
Why milk jugs don't work
Milk jugs aren't measuring devices. Their shape, handle, and empty space at the top make it impossible to judge an exact gallon by sight.
How officials actually test pumps
State and local inspectors use specially designed containers to measure fuel accurately. They pump a set amount and compare it to the pump display.
The serious safety risk
Milk jugs aren't made to hold gasoline. The U.S. Consumer Product Safety Commission warns they lack the construction and safety features of approved fuel containers.
“Gasoline emits flammable vapors, and a milk jug lacks the construction and safety features of an approved fuel container.”
What to do instead
If you suspect a pump is inaccurate, keep your receipt, note the pump number and fuel grade, and report it to your state or local weights and measures office.
The bottom line
Milk jugs aren't designed to measure fuel accurately, and putting gasoline in them creates a serious fire hazard. Report suspected pump problems to your state's weights and measures office instead.
