With gas prices pushing ever higher most of us are looking for ways to increase our gas mileage. You will have heard of terms like hypermiling and water4gas but really the simplest thing you can do to increase your gas mileage is to change your driving habits. Here are some free tips to increase your gas mileage immediately, no matter what kind of car you drive. 1. Keep to the speed limit. Actually its better to drive below the speed limit, in most modern cars the optimum speed is around 40 mph as wind resistance becomes a major factor. 2. Dont accelerate or brake hard. Remember, your car burns extra gas when accelerating and whats the point of burning all that gas just to brake hard and lose all of the energy when you get to the next junction. 3. Buy a GPS - taking the optimum route for your journey will save more money on gas than the GPS unit costs over the life of the car, and the wife and kids wont be shouting at you for getting lost! 4. Check your tire pressures regularly and make sure your car has regular services. One of the best ways to increase your gas mileage is to ensure that your tires are not worn, (this is also essential for road safety) and they are inflated to the correct pressure. Under inflated tires cause extra drag and just eat up that extra gas. Have your wheel alignment and shocks checked - these two factors will significantly affect your gas mileage, especially at higher speeds. Make sure your air filter, fuel filter, spark plugs and engine tuning are all carried out at recommended service intervals - remember a healthy engine is a lean engine. 5. Don't run unnecessary electrical services. Switch off your air conditioning - this really guzzles the gas. Only use your headlights if you need them - Volvo drivers are excused on this one. Basically, every electrical service ultimately gets its power from your gas, and burning gas to keep you comfortable has a very bad effect on your gas mileage. 6. Keep your windows up. Open windows cause wind resistance, reducing your gas mileage by 10%. The only exception to this is when its unbearably hot as its actually still more efficient to keep your windows down that to run your air conditioning. 7. Share your car. Bit obvious this one but many people never even consider it. You can increase your gas mileage by 50% when car sharing with your workmate on alternate weeks, for example.
