Does my driving style affect my gas mileage?
Absolutely. If you're an aggressive driver, one of the best ways to improve fuel mileage is to avoid sudden starts. That means forfeiting all of those stoplight-to-stoplight races around town, and putting the "pedal to the metal" a little less often. By gradually accelerating, the engine doesn't have to work as hard at getting the vehicle's heft up to speed, thereby increasing efficiency.
Can I save money by using regular grade gas instead of premium?
Manufacturers make sure to note (in owner's manual, on gas cap or fuel door) what type of gas you should use. Typically, sports cars require premium fuel for optimum performance. In these cases, the vehicle may end up running a bit rough if you run it on regular. Conversely, many people believe that filling their tanks with premium fuel is "better" for the car, even if it isn't necessary. Not true. If the manufacturer doesn't suggest or require you to buy high-octane gas, stick with less expensive, 87-octane regular.
How can I get better mileage from my older vehicle?
As cars get older and rack up mileage, it's inevitable that they will become less efficient. But, there are a few things you can do to abate that problem. Make sure your tires are properly inflated. Under-inflated tires increase rolling resistance (friction) and require more effort from the engine to maintain momentum. Also, stick to the manufacturers maintenance schedule. Something as simple as replacing a dirty air filter can help to improve fuel economy.
