Summer is here which means more traveling for you and your whole family. Fuel efficiency is on our minds more when we are driving more. Most of us can't just dash out and buy a new, more economical car. Also, for many of us, a smaller economy car just does not meet the needs of our family or business.
In reality, replacing a good reliable car just to gain a few miles per gallon may not be the most economical or environmentally friendly move anyway.
Today I thought I would offer some tips that can help you get the most out of every gallon of gas for the vehicle you drive now.
Let's start with the basics like tire pressure, since low tires can rob you of several miles per gallon. For every 1-pound drop in pressure on all four tires, you increase your rolling resistance by 1.4 percent. Based on that, you can see how being down several pounds on air pressure can increase rolling resistance by quite a bit. Look on the door sticker of your vehicle for

Q. If the manufacturer says a vehicle needs premium fuel, what happens if you use mid-grade or regular?
A. The car will run on regular, but it has been designed to run on the higher octane fuel. The simplest way to describe this is in order for it to run on regular gas, the computer will need to detune the engine a bit, sacrificing performance and fuel economy.
As a result, you will probably burn more fuel and gain nothing in cost savings -- and your car will not run optimally.
If your car calls for premium fuel, you should put premium fuel in it, and if your car does not call for premium fuel there is no advantage to you using it
Fuel economy, according to the Car Care Council, is directly related to vehicle care and driver behavior. Both can have a significant impact on how much motorists pay at the pump.
•Underinflated tires can impact the vehicle's fuel economy. When tires aren't inflated properly, it's similar to driving with the parking brake on and can cost a mile or two per gallon.
•Dirty air filters also can waste gas and cause the engine to lose power. An air filter that is clogged with dirt, dust and bugs chokes off the air and creates a "rich" mixture, which is too much gas being burned for the amount of air. Replacing a clogged air filter can improve gas mileage by as much as 10 percent.
•Worn or dirty spark plugs can cause misfiring, which wastes fuel. Vehicles can have four, six or eight spark plugs that fire as many as three million times every 1,000 miles, resulting in a lot of heat and electrical and chemical erosion. Spark plugs t
