Is It Worth the Effort to Drive to a Cheaper Gas Station?

Determining whether it is financially beneficial to save a few cents per gallon by driving to a cheaper gas station is a common consideration for many drivers. However, the decision involves a range of factors from fuel efficiency to time and cost. Let's explore these in depth to help you make an informed decision.

Factors to Consider

When evaluating the cost of making the extra drive, it's important to consider several key factors, including distance and time, the cost of additional fuel, the savings from cheaper gas, and the net savings.

1. Distance and Time

If you're driving one mile to a cheaper gas station, the round trip will be an extra two miles. To calculate the time, we can use the speed limit to estimate the duration. Assuming a speed limit of 30 mph, one mile will take 2 minutes, making the round trip 4 minutes or 1/15th of an hour.

2. Cost of Additional Fuel

The next factor to consider is the cost of the additional fuel used for the extra trip. For instance, if your car gets 25 miles per gallon (mpg) and you drive an extra 2 miles, you'll use approximately 0.08 gallons of fuel (2 miles / 25 mpg). If gas costs $3.00 per gallon, the additional fuel cost for the round trip is:

0.08 gallons × $3.00 per gallon $0.24

3. Savings from Cheaper Gas

Now, consider the savings from driving to the cheaper gas station. If you fill up 10 gallons of gas, the savings are:

10 gallons × $0.03 per gallon $0.30

4. Net Savings

To calculate the net savings, subtract the additional cost of driving from your savings:

$0.30 – $0.24 $0.06 (6 cents)

In this specific example, you would save 6 cents by driving the extra mile.

Conclusion

The net savings might not justify the extra effort or time if the trip is solely for filling up your tank. However, regular travelers or those with other errands in the area might find the savings more worthwhile. It's also important to consider your earning potential and the amount of fuel you typically purchase.

Impact of Your Earnings and Fuel Consumption

Let's break down the scenario further:

Assume you earn $15 per hour. The 4-minute round trip would cost you $1 in time value. To break even, you need to save at least $1 more, which means you need to purchase more than 33.33 gallons of fuel (one dollar / three cents per gallon). If your earning potential increases to $60 per hour, the 4-minute round trip would cost you $4 in time value. To break even, you'd need to purchase over 132 gallons of fuel (one dollar / three cents per gallon).

Final Thoughts

Only in scenarios where your earning potential is under $7.50 per hour and you are purchasing at least 17 gallons of fuel would it start to make financial sense. For the average car, this rarely happens. Evaluating the cost and time savings is crucial to making a decision that benefits you financially.

Key Takeaways:

The net savings from cheaper gas may not justify the extra effort and time, especially for short trips. The decision should be based on regular mileage, the amount of fuel purchased, and time value.
