Simple test checks gas pump accuracy

With gas prices approaching $4 per gallon for regular 87-octane fuel, many people are interested not only in the price but also in the accuracy of the pump from which the liquid gold pours.
Here’s a simple test to make sure you’re getting what you pay for at the pump. It’s called the 10-gallon test.
The next time you buy gas, pump exactly 10 gallons into your tank. If the price is $4.00 per gallon, the total price should be 10 times the per-gallon price or exactly $40.00. If the total amount of the sale gets to $40 before you’ve pumped 10 gallons, the pump is not accurate.
Complaints about inaccurate gas-pump measurements should be made to the New York State Department of Agriculture, Bureau of Weights and Measures whose telephone number is 518.457.3146.
