Q. How far out of your way should you drive to save on gas?
A. That depends on quite a few factors: your car's mileage, how much gas you're buying, the price today and distance between stations.
But we played with Excel spreadsheets for a while, and have some answers.
Let's say one station is 5 cents a gallon cheaper than another. That's pretty common. And you need 10 gallons. Sorry, but there's only a 50-cent difference on that tank. Just 50 cents. Total.
If you drive a car that gets 28 mpg in the city (that's pretty good), at today's prices of about $3.50 a gallon, it costs you 13 cents to drive a mile.
Your break-even point for that 5-cents-cheaper gasoline is just four miles. From Raymond James Stadium to Channelside is about six miles. Don't drive any further to save a nickel per gallon.
Here are some other nickel/break-even points at $3.50 a gallon. Any further, and you're losing money trying to save money.
•10 mpg: About one mile
•14 mpg: 2 miles
•21 mpg: 3 miles
•28 mpg: 4 miles
•35 mpg: 5 miles
•40 mpg: 6.5 miles (Good for those Prius owners out there.)
