The cost of owning a car can be overwhelming, and one of the most significant expenses is fuel. With the ever-rising prices of gasoline, it’s no wonder that many car owners are concerned about their vehicle’s gas mileage. If you’re finding that your car is not getting the fuel efficiency it once did, you’re not alone. In this article, we’ll explore the reasons why your car might be bad on gas and what you can do to improve its fuel economy.
Common Reasons Why Your Car Is Bad on Gas
There are several reasons why your car might be consuming more fuel than it should. Here are some of the most common causes:
Tire Pressure
Tire pressure plays a significant role in your car’s fuel efficiency. Underinflated tires can increase rolling resistance, which can decrease your car’s gas mileage. Proper tire pressure can improve your car’s fuel economy by up to 3%. Check your tire pressure at least once a month and before long trips.
| Tire Pressure | Recommended Pressure |
|---|---|
| Front Tires | 35-40 PSI |
| Rear Tires | 35-40 PSI |
Dirty Air Filter
A dirty air filter can decrease your car’s fuel efficiency by up to 20%. A clogged air filter can cause your engine to work harder, which can increase fuel consumption. Replace your air filter every 15,000 to 30,000 miles or as recommended by your car’s manufacturer.
Low Octane Fuel
Using low-octane fuel in a car that requires high-octane fuel can decrease your car’s fuel efficiency. Check your car’s owner’s manual to see what type of fuel it requires. Using the correct type of fuel can improve your car’s fuel economy by up to 5%.
Worn-Out Spark Plugs
Worn-out spark plugs can decrease your car’s fuel efficiency by up to 30%. Spark plugs that are worn out or fouled can cause your engine to misfire, which can increase fuel consumption. Replace your spark plugs every 30,000 to 100,000 miles or as recommended by your car’s manufacturer. (See Also: Does Sitting with Your Car on Waste Gas? Waste Your Money)
Driving Habits
Your driving habits can also affect your car’s fuel efficiency. Aggressive driving, such as speeding and rapid acceleration, can decrease your car’s fuel economy by up to 33%. Additionally, idling for extended periods can also decrease your car’s fuel efficiency. Try to maintain a consistent speed and avoid idling whenever possible.
How to Improve Your Car’s Fuel Economy
There are several ways to improve your car’s fuel economy. Here are some tips:
Regular Maintenance
Regular maintenance is essential to improving your car’s fuel economy. Make sure to follow your car’s recommended maintenance schedule, including oil changes, tire rotations, and spark plug replacements.
Check and Maintain Fluid Levels
Check your car’s fluid levels regularly, including the oil, coolant, transmission fluid, and brake fluid. Low fluid levels can cause your car’s engine to work harder, which can decrease fuel efficiency.
Avoid Idling
Idling for extended periods can decrease your car’s fuel efficiency. If you’re going to be stopped for more than 30 seconds, turn off your engine. This can improve your car’s fuel economy by up to 20%.
Remove Extra Weight
Removing extra weight from your car can improve its fuel economy. Extra weight can decrease your car’s fuel efficiency by up to 1% for every 100 pounds of weight added. Remove any unnecessary items from your trunk or back seat to improve your car’s fuel economy. (See Also: Why Won’t My Car Take Gas? Common Causes Revealed)
