Gas Mileage 101

The number of miles your car can drive on one gallon of gas is referred to as gas mileage, or miles per gallon (MPG). This is also known as fuel economy. The more miles per gallon your car gets, the more fuel efficient it is.

To achieve the highest level of fuel economy possible for your vehicle, the key is regular maintenance and quality automotive parts and products. The better you care for your car, the better it will perform and the longer it will last.

To understand your vehicle’s routing car maintenance needs, refer to the owners’ manual. If you do not have the owners’ manual, you can download one online for your make and model vehicle, or you can ask a trusted Carmel IN mechanic for a recommended auto maintenance schedule.

Calculating Your Vehicle’s MPG

There are 7 simple steps to calculating your vehicle’s miles per gallon. It will take some time, as well as some basic, elementary-level math. Here’s how to determine a car’s MPG:

Fill Your Tank All the Way – Be sure your gas tank is topped off all the way.

Record the Odometer Reading – Write down the number of miles that reads on your odometer. You may also set your odometer’s trip meter is applicable.

Use Up All Your Gas – Drive your vehicle as you normally would until the gas tank is on E again. This should take a week or so depending on how much and how far you drive on a daily basis.

Record the Odometer Reading AGAIN – Write down the number of miles that shows on your odometer.

Record the Number of Gallons Refueled – Write down how many gallons of gas it took to refuel your tank all the way full.

Do the Math – Subtract the first odometer reading from the second reading. This will tell you how many miles your car drove on one tank of gas.

Do Some More Math – To get your MPG, divide the number of miles you drove by the number of gallons it took to refill your gas tank.

Does Your Car Have Good Fuel Economy?

The U.S. Environmental Protection Agency provides us with a fuel economy rating system that evaluates vehicles on a scale from 1 to 10, with lower numbers being worse and higher numbers being better. If your vehicle has an MPG less than 14, you are assigned a rating of 1, while a MPG of 44 or more rates a full 10.

When a Fuel Pump Goes Out

The fuel pump plays an important role in the overall driveability and operation of a vehicle. Without a properly operating fuel pump, the engine will not get the fuel delivery needed to start. There is a necessary fuel-to-air ratio that must be met in order for the engine to get the power needed fuel the cylinders and fire up the pistons.

Because of the unique role of the fuel pump, the signs are often easy to spot. If you notice any automotive malfunctions or changes in your car’s performance, your car might have a bad fuel pump, in which case, your likely recourse is fuel pump replacement.

Common Signs of a Fuel Pump Problem

Failed Ignition Attempts

Can you get your car to start? If you are experiencing multiple failed attempts when trying to start the car, you should have your fuel pump checked out. Most often, this is due to structural damage of the fuel pump itself, but sometimes, the pump is just clogged. If the car will not turn over at all, fuel pump damage is the likely culprit. If the engine cranks but won’t turn over all the way, you may just be dealing with a clogged fuel pump.

Sputtering and Stalling

If your car is routinely sputtering or stalling while driving, it could be an indication of a failing fuel pump. In most cases, the fuel pump is working at a low pressure, so the engine is not getting the fuel it needs to generate combustion. If the car starts, drives away, but then stalls, it is usually because your fuel pump is not doing its job, and the engine cannot keep the car running.

Rear Bumper Whirring

Backseat noises like whirring or humming can point directly back to the fuel pump. These noises are naturally generated by the operation of the fuel pump, but we usually cannot hear them. When the fuel pump starts to malfunction, it is forced to work harder, which can make the noises get louder.   

Engine Surging

Do the engine revolutions randomly surge and swell while you drive? This is a common sign of a faulty fuel pump. Opposite of fuel pump clogs and low pressure, engine surging is caused by a malfunction that sends too much fuel to the cylinders. This often causes the car to suddenly pick up speed and soon after, slow down.

Increased Fuel Consumption

Noticing changes in gas mileage, specifically reduced gas mileage, is a common indication of a fuel system problem. As for the fuel pump, it can be responsible for increased gas consumption when its internal parts and bearings deteriorate or break. Deterioration or damage can cause extra gasoline to be sent to the engine, which goes unused.
