While additive diesel fuel will improve mpg in the engine, a better driving technique brings the advantage of being absolutely free. Adjusting the nut behind the wheel (guess who that is) is possibly the most efficient and cheapest modification a person can ever make to improve fuel economy.Plus, you can install the method in any car!Let’s save some money and look at what WE can do. But, of course, Safety First – every time (and keep it legal, of course)!1. Drive lessMove and live closer to work, carpool with friends, use public transportation, do more each time you do go out by combining tasks, work from home if you can.2. Remove all that junk from your trunkUnnecessary junk is weight you carry in your trunk and it doesn’t ride free. It takes energy to go back and forth, up and down. Removing unnecessary weight from your vehicle saves fuel.3. Remove the roof rackHow often do you use it? Sure, it looks pretty, but it creates extra drag and drag costs $$. Which flies easier – an arrow or a brick?4. Check your tire pressures every weekMake sure that your tire pressures are set right. A little higher doesn’t hurt, because it reduces rolling resistance – but don’t go crazy. Too high and you will ruin the center part of the tread. Too low and you’ll ruin the side-wall – and lower your mpg to boot.5. Leave in good time – no last minute rushing to catch upLeave a few minutes early so you don’t have to drive faster. Driving at a steady speed saves fuel.6. Turn off when you stopIf you are going to be stopped for more than a minute, then turn off. It won’t hurt your car, but it will help your bank account. Play safe here – watch the vehicles around you. Make sure your battery and starter are up to the task.7. Avoid heavy brakingBrake early, and gently. It not only saves your brake linings, but you automatically tend to avoid accelerating too fast in the first place. Remember, you left early – no hurry here.8. Avoid rush hour trafficIt’s always more of a rush, with more start-stop driving etc. You can’t turn off every five seconds. No, drive before or after the rush, if you possibly can.9. Avoid stoppingIf you look well ahead, you can plan better. The light is about to go red on you. Slow down immediately. If you time it right, you might not need to stop – keep rolling and conserve momentum.10. Cold air costs moneyAir conditioning and heating isn’t free. It loads the alternator, and that costs gas. Take it easy, especially at lower speeds.11. Close the windows and the moon roof (sunroof, whatever you call it)Modern vehicles are designed to slip through the air with maximum efficiency. They are designed with closed windows in mind. If you drive at high speed with open windows and moon roof, etc. all you are doing is increasing turbulence and wind resistance.12. Start and GoModern engines don’t need to warm up before moving off. Standing with an engine running means zero mpg!Lucky 13. Courtesy – even in trafficDriving with a good gap when following traffic, gives you more time to react and avoid abrupt changes in speed.14. Look well aheadThe further you look ahead, the more time you have to avoid abrupt changes in speed or direction. Both these changes waste gas, and tires too! If you look at the rear of the car in front of you, it’s both rude (just kidding!) but also an invite for squealing tires, when you realize – too late – that the traffic is stopping.15. Take off smoothly and accelerate smoothlyThis is possibly the number one way to save gas. Hitting the gas might sound and feel good, but you’re hurting your bank account! Take it easy.16. Last but never leastMake sure your car is serviced according to the manufacturer’s manual.You’re finding this too complicated? Then forget adjusting the nut - you need an additive diesel fuel. If you absolutely cannot do any of the above, take the pill. Try out this product, that is tried and true – you’ll save money – but drive safe anyway.
