How do I get the best gas mileage on a highway?
How do I get the best gas mileage on a highway?
Avoid Speeding Increasing your highway cruising speed from 55mph (90km/h) to 75mph (120km/h) can raise fuel consumption as much as 20%. You can improve your gas mileage 10 – 15% by driving at 55mph rather than 65mph (104km/h).
What are the benefits of fuel efficient driving?
Fuel-efficient driving has important environmental benefits, too. Fuel-efficient driving techniques burn less fuel than other, more aggressive driving styles and thus produce fewer greenhouse gas (GHG) emissions, the leading cause of climate change.
Is it more fuel efficient to drive faster?
The short answer: Nope. The reason: The common understanding is that going faster burns more fuel and therefore, the slower you drive, the less fuel your car will use, but this actually isn’t true. Most cars’ peak fuel efficiency occurs somewhere between 50-60 miles per hour.
How do you drive with fuel efficiency?
Adopt these 5 fuel-efficient driving techniques to lower your vehicle’s fuel consumption and carbon dioxide emissions by as much as 25%.
- Accelerate gently. The harder you accelerate the more fuel you use.
- Maintain a steady speed.
- Anticipate traffic.
- Avoid high speeds.
- Coast to decelerate.
Why does my car use less fuel on the highway than around town?
But in the country we tend to make longer journeys, don’t stop as much, and that means we’re able to run more at a steady speed. Our engines aren’t at their most efficient when warming up from a cold start and fuel consumption during that phase is higher than it is once the engine is warmed-up.
Why is highway mileage better than city mileage?
But typically, your mileage is better on the highway than the city because braking losses waste more than aerodynamic losses. Valve timing is a major source of variation in engine efficiency.
Why does a car lose efficiency at high speeds?
Driving fast on the interstate loses efficiency mostly due to aerodynamic drag. My old CRX has good aerodynamics, but at really high speeds it doesn’t matter: it gets 50 MPG at 70 MPH, but less than 30MPG at 95 MPH. Air drag dominates at those speeds. Braking in a gasoline-powered car converts kinetic energy into heat.
What can I do to improve my car’s fuel economy?
Rear-mount cargo boxes or trays reduce fuel economy by much less—only 1% or 2% in city driving and 1% to 5% on the highway. If you need to use an external cargo container, removing it when it’s not in use will save fuel and money. Avoid keeping unnecessary items in your vehicle, especially heavy ones.

How to improve gas mileage in the city?
There are a few ways to improve your gas mileage in the city, and they all coincide—fortunately—with safe driving practices. The best thing you can do is drive gently: accelerate and stop at a controlled rate and try to spend as little time as is possible with your car idling.
