Everyone knows how to determine if their car is running low on gas. However, not everyone knows how to improve their gas mileage. With fuel prices hovering at record levels over the past few months, now is the best time to learn about what you can do to improve fuel efficiency.
Here are some tips and tricks for better gas mileage. Use these tips and you’ll see an improvement in gas mileage by of about 15%.
Get new spark plugs
Most people assume that their car’s spark plugs will last well over 100,000 miles. Unfortunately, this isn’t true for some vehicles. This is especially true if you own a car with a turbocharger. With these vehicles, you’ll need to replace them every 30,000 miles.
It is best to change your spark plugs early, preferably before it reaches 30,000 miles. Incomplete combustion and misfires may occur during the last 20,000 miles. At this stage, your spark plugs are already 80% worn. It is not a good idea to squeeze the last drop of life out of your spark plugs.
Lighten your load
You may not think about it that much, but the junk on your trunk can hurt your fuel economy. In fact, fuel efficiency decreases by 1 to 2% for every 100 pounds of weight in your vehicle. Don’t carry around items you don’t need. Get the junk out of the trunk. Not only will it improve the balance of the car, it also improves fuel efficiency.
Check your tire pressures
This is an important aspect of car maintenance, but a lot of people tend to overlook it. Proper tire maintenance will not only ensure safety, it also helps improve fuel efficiency. Low tire pressures can lead to tire blow-out, uneven tire wear, and poor gas mileage. Every pound of pressure that is missing will cost you rolling resistance. Check your tire pressures regularly and make sure that you have the correct tire pressure.
Change octane if you can
Most vehicles just need regular gas. However, a lot of car owners drive around with medium or premium gas in their tank. Sure, higher octane gas gives you less probability of detonation. Unless you have a high compression engine, putting mid-grade or premium gas is nothing but a waste of money.
Majority of cars will run safely and efficiently on the cheapest petrol. There is no need to spend money high-octane petrol. This may not help improve fuel efficiency, but it will help you save money.
