Updated Information. Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by roughly 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic. ... Sensible driving is also safer for you and others, so you may save more than gas money.

What is the most fuel efficient speed to drive at?
The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it's illegal too).
Does Cruise Control save diesel?
Generally speaking, yes. Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.
Does a car get better gas mileage when the tank is full?
Reducing the weight of your car by 2.5% (by only filling your tank half full) would not have a noticeable effect on your fuel consumption. When all is said and done, there isn't a huge difference in fuel consumption, but there are some definite pros to filling your tank.
Do you get better gas mileage going faster or slower?
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.
Why is my mpg going down so fast?
A bad fuel injector or dirty/old fuel filter can drastically affect the flow of fuel into the engine. A fuel system problem is one of the most common causes of poor gas mileage. The more you run your A/C, the lower gas mileage you will get.
Is 30 miles to the gallon good?
Don't expect to attain higher than 20 mpg overall with a non-hybrid, and most offer less than 30 mpg on the highway. The best fuel-efficient non-electric vehicles get the following EPA-estimated combined numbers: Small Pickup: Chevrolet Colorado 2WD Diesel and GMC Canyon 2WD Diesel get 23 mpg.
Do diesel cars need to be driven regularly?
So it is advised that drivers regularly give their diesel vehicle a good 30 to 50 minute run at sustained speed on a motorway or A-road to help clear the filter. However, not all drivers do this type of driving regularly – which is why manufacturers have designed an alternative form of regeneration.
What RPM does diesel engine most efficient?
Most diesel engines have the peak torque produced between 2000 – 2500 RPM. Maintaining your RPM at around 2000 RPM will give you the maximum efficiency and will also keep the engine rev happy. Try and quickly up shift to higher gears, so that you can maintain a lower RPM at high speeds.
Is 56 mph the most economical speed?
Generally speaking, there is no one driving speed which is optimum for fuel economy. ... This was due to the old fuel consumption test being run at three speeds: urban, 56mph and 75mph – and 56mph was always, unsurprisingly, the most efficient of these. Typically, cars are most efficient at 45-50mph.
What diesel engine gets the best fuel mileage?
The Winner Is: Chevy Silverado 1500 2WD!
The new Chevy Silverado offers the best fuel economy for a diesel truck. It gets 33 MPG highway, 22 MPG city, and 27 MPG combined.
