You've probably noticed a bunch of warning lights on your dash when you start your engine. They flash on to test the circuits and then go off if everything's OK. One of the warning lights looks like a car battery. Its job is to tell you if your battery's not charging properly.
When driving around town, your family car engine needs clean air to burn the fuel – and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas.
All that air passes through a filter that catches the dust and dirt. Eventually the filter gets completely full. Because the filter can only hold so much, dirt starts getting through. This dirty air passes through the mass airflow sensor, and starts to accumulate on the delicate sensor element. The mass air flow sensor measures how much air is getting into your engine. When the airflow reading is incorrect, your family car engine doesn’t get the proper amount of fuel. It runs rough and doesn’t perform as well as it should.
It doesn’t matter if the car you’re driving is new or old, big or small. There are preventive maintenance steps every vehicle owner can take to make sure their car is as “green” or environmentally friendly as possible, according to the Car Care Council. By following a few simple preventive maintenance steps, you can help protect the environment by improving gas mileage, which in turn saves money at the pump.
Keep your car properly tuned for optimum performance- Regular tune-ups, maintenance and having clean air filters will help your car pollute less and burn less gas. Getting a tune-up can improve gas mileage by an average of 4 percent. Simply changing the car’s air filter can improve efficiency by 10 percent. Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve gas mileage by as much as 40 percent.
First, Simply Drive Safely
Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, so you may save more than gas money. Fuel Economy Benefit: 5–33% which equivalent in gasoline savings to $0.18–$1.19/gallon
You can improve your gas mileage by 1–2 percent by using the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1–2 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1–1.5 percent.
