One way to check the health of that car out in your McCullom Lake driveway is to monitor the car's fuel efficiency. |
If you haven’t thought about it this way, you may not want to know how much it costs you to drive somewhere. After all, will it help you to know that a 3-mile trip from your McCullom Lake home to Jewel in McHenry may cost you 48-cents to get there and another 48-cents to get back?
Of course, the cost of that trip, in terms of fuel consumption, depends on some variables. For instance, what was the cost of fuel per gallon? How many miles per gallon (mpg) do you get in your vehicle? How heavy is your foot on the gas pedal when you drive? Were you stuck in construction traffic with the motor running?
The idea that the trip would cost you 48-cents assumes that your vehicle gets 25-mpg and you purchased the fuel for $4 per gallon. But why should you want to know that?
If you do have a lead foot when driving, seeing what it costs you to go somewhere may encourage you to go a little lighter on the gas pedal. Depending on your finances, you may scrutinize the necessity of going somewhere before deciding to take a trip. But tracking your vehicle’s fuel efficiency isn’t really about moderating your driving habits.
The real reason you may want to track your gas mileage is that it’s like taking a vehicle’s temperature to make sure it’s not sick.
If, suddenly, your car’s fuel efficiency falls dramatically, you want to ask yourself why? If it has something to do with a deviation from your customary driving habits, at least you’ll know and you can determine what to do about it. But that’s usually not a factor behind a significant change in a vehicle’s fuel economy.
If your vehicle’s mpg drops all of a sudden, there’s a good chance that something is wrong. A problem that affects fuel efficiency can also represent a problem that is doing damage to your car’s engine. Low tire pressure can negatively impact your car’s mpg but you probably wouldn’t expect it to have that big of an effect. Whatever it is, you’ll want to look into it sooner than later.
You might say that tracking your vehicle’s mpg is like taking its temperature. You just want to make sure that it’s healthy.
Checking the gas mileage is fairly easy – it requires a simply mathematical formula.
- Determine how far you drove between fillups at the pump
- Record the miles on the odometer when you fill the tank
- Record the miles on the odometer the next time you fill up
- Subtract (2) from (3) – that gives you the number of miles driven between fillups
- Record the number of gallons of fuel you’ve pumped into the tank with your latest fillup
- Divide the number of miles driven (4) by the number of gallons (5) you’ve pumped into the tank
This number represents your miles per gallon.
Do this every time you fill the tank and you’ll have a running record of your vehicle’s mpg. And the next time you back out of your McCullom Lake driveway, you’ll have an idea if your car’s engine is running efficiently or not.
