There are two major categories in fuel savings:
- driving habits
- vehicle maintenance/upgrades
First, DRIVING HABITS:
- Anticipate, use your brakes less, and don’t accelerate quickly. Look far down the road ahead, even if “far” is a city block. Get into turn-lanes smoothly and early: avoid accelerating to get in front of traffic. Anticipate stops or slow-downs ahead and take your foot off the gas: try to coast much more than you brake. Additional coasting distance saves fuel and extends brake-pad life. Remember: he who leaves stoplight quickest pays more at pump.
- Use Cruise Control. It saves fuel and speeding tickets. But it’s not just for cruising. The “Resume” button can give you decent acceleration without wasting fuel.
- Overdrive and gear selection. If your automatic has Overdrive, use it. If you have a manual transmission, shift early to keep engine rpm’s lower and always use the highest gear for highway cruising.
- Slow down. As you increase speed above 60 mph, wind resistance increases rapidly as a percentage of total fuel consumption. Typically, every mile over 60 mph costs you ~1% in fuel economy.
- Carefully consider your route and the time of day: traffic flow is a huge factor. For example, say that along your interstate travel route, the space between vehicles averages 3 to 4 car lengths… typical of traffic in many large cities. If it’s stop-and-go, fuel economy will be bad. But if traffic is moving smoothly and fast (at 60 – 80 mph), then fuel economy can be superb: those rushing vehicles create a jet-stream of air that dramatically reduces wind-drag losses. Up to 30% gains are possible. For maximum fuel economy, follow a larger vehicle and use cruise control. Also keep in mind wind direction: if the wind blows strongly from the right and you’re in the right lane, you’ll get NO break in wind resistance from vehicles ahead.
- Plan and Combine errands to make fewer trips. Think like your great-grandparents did. Plan meals and grocery shop once a week to once a month: just make a list of other errands during the week, plan your route, and do it all in the same trip. Arrange with other parents to carpool or pick up the kids for you. Such planning may seem like work at first, but it frees up time, helps you relax, and can improve your average fuel economy by 5 to 15%. It can also cut your average weekly miles by 20% or more. Total dollar potential: save 10-35% of monthly fuel costs. How does this help fuel economy? During the first several miles while warming up, the engine and transmission are not operating efficiently. This is why city fuel economy can drop dramatically in cold weather, when it can take 10 miles for the engine and petshub.xyz to warm up. Automatic transmissions in particular can be power hogs when fluid is cold, and manual transmissions can feel like you’re shifting in molasses. (Hot/cold temperatures are one of many reasons to use a full-synthetic 100,000-mile transmission fluid). So, combining two or three trips into one reduces the miles you drive, and also gets you better fuel economy.
