Gas prices getting you down? CarCheckup has gathered the five best bets that you can use today to lower your fuel consumption.
1. 55 mph instead of 65 mph saves you 15% on fuel
Each make/model/year of car has it’s own fuel efficiency numbers. A full size SUV will have lower fuel economy than a new small sedan. The math still holds though: dropping 15% of your fuel economy can make a big difference to your weekly fuel cost.
Assuming a cost per gallon of $4.00 per gallon, that extra 10mph is costing you $0.60 per gallon. If your gas tank is a 15 gallon tank then you’re spending an extra $9 per fill up on average.
Time is money and there just aren’t enough hours in a day, but let’s use an example to see what the actual impact of that extra speed buys you.
Let’s assume your car gets 30 miles per gallon on the highway at the posted speed limit of 55. You need to make the trip from Indianapolis to Chicago,about 165 miles one way, for a client meeting.
| Average Speed | Drive Time | Fuel Economy | Cost of Fuel ($4/gal) | Time Savings compared to 55 MPH | Extra Fuel Cost |
| 55 | 180 minutes | 30 mpg | $22.00 | – | – |
| 65 | 150 minutes | 25.5 mpg | $26.40 | 30 minutes | $4.40 |
| 75 | 132 minutes | 20 mpg | $33.00 | 48 minutes | $11.00 |
Save even more money by tracking your business mileage! Round trip, at the 2011 IRS business mileage deduction rate of .51/mile, will give you a cool $168.30 mileage deduction come tax time. (Need a simple business mileage tracking solution? See if CarCheckup.com is right for you)
Fun Fact: The average cost for a speeding ticket is $150 in the US. If you get caught speeding that will increase your trip cost as well!
2. Rapid Acceleration/breaking can drop mileage by up to 33%
Aggressive driving (hard acceleration, hard breaking, and excess speed) can drop your mileage my up to 33%! That’s like choosing to spend an extra $1.49 per gallon by hammering the gas after each stoplight turns green and stopping aggressively slamming the breaks when you approach a stoplight. Simply adjusting driver performance by accelerating slowly and coasting towards a light can make a huge impact on your fuel economy.
3. Clean out your trunk! Every extra 100 pounds reduces your fuel economy by 2%
You don’t have 100 pounds of junk in your trunk, right?
Do you put bags of sand or salt in your trunk to help with winter traction? Are you still lugging it around with you now? That could be well over 100 pounds by itself!
Now that we’ve taken care of that: What else do you have in there that you really don’t need to carry?
4. At Idle you get ZERO miles per gallon
The average passenger sedan burns car at idle burns approximately one gallon of gas per hour of idling.
It may not seem like a lot, but it really adds up!. Let’s take a look:
| Daily Idle Time | Gallons Per Day | Cost Per Day (@$4.50/Gal | Gallons Per Month | Cost Per Month (@$4.50/Gal | Gallons Per Year | Cost Per Year(@$4.50/Gal |
| 15 min | .25 | $1 | 5 | $23 | 60 | $270 |
| 30 min | .5 | $2 | 10 | $45 | 120 | $540 |
| 45 min | .75 | $3 | 15 | $68 | 180 | $810 |
| 60 min | 1 | $5 | 20 | $90 | 240 | $1,080 |
| 120 min | 2 | $9 | 40 | $180 | 360 | $2,160 |
As you can see, even small changes in driver behavior can have a huge impact on fuel spend over the course of a year. One of the best ways to increase fuel economy is to reduce idle time.
5. If you’re check engine light is on, find out why and fix it!
Did you know that a bad O2 sensor can reduce your fuel economy by up to 40%? Or that a failed gas cap seal can cost you 5% of your fuel economy? The EPA originally mandated the use of OBDII technology to aid in monitoring emissions related systems. If you’re check engine light is on there is a solid chance that your gas mileage is being impacted. These two check engine light codes are among the most popular seen in the CarCheckup system.
CarCheckup.com can help you find these issues as well make tracking driver performance and business mileage for you or your fleet painless.

Busy drivers hurrying between appointments can have a tendency to speed to make up time. The few minutes that they make up by speeding…just a little bit.
