Besides using cruise control, you can also apply the following tips to save fuel. The tire pressure monitoring system, or TPMS light, typically looks like parentheses with an exclamation mark or dot in the middle. Letting your tire pressure drop below 25 psi can cause an increase in friction, De Haan said, forcing the engine to work harder and getting you fewer miles per gallon. She does discourage turning your car on and off in stop-and-go traffic, however. "Driving safely means being able to respond quickly to traffic conditions," Gaines said. "If people drove at a slower pace of acceleration and avoided racing through a red light, it would help them prevent [...] burning through gas and using energy," he said.
Does Cruise Control Save Gas? Is It Better For Gas Mileage?
Each time you accelerate, your engine consumes more fuel, and braking wastes the energy that could have been used to maintain your speed. Highways, on the other hand, offer a more consistent flow of traffic, allowing you to maintain a steady speed and improve your fuel efficiency. So, whenever possible, try to avoid congested areas and opt for routes with smoother traffic flow. In addition to maintaining a consistent speed, cruise control can also help reduce speed variations.

Adaptive Cruise Control is the newest form of cruise control in vehicles today. ACC works by adjusting the speed of your car to the flow of traffic as you drive. ACC systems can sense road speed, but they also can register the presence of other vehicles. So, the simple and correct answer to the question of does cruise control help you to use less gas is yes, but only in the right circumstances. Additionally, the cruise control system is often designed to operate more efficiently than an average driver, making subtle adjustments to optimize fuel use.
Benefits of Using Cruise Control
Early cruise control used a device called a “flyball governor,” which used centrifugal force to spin two balls mounted to a shaft, connected in turn to the throttle valve. As load increased, the balls spun and raised a sliding ring that caused the throttle to open. That allowed a vehicle to maintain a steady speed, even when climbing inclines. Cruise control—particularly adaptive cruise control—can help you save fuel. Before we get into how cruise control can contribute to efficient driving, let’s get an understanding of what this function is, and where it came from. Yes, Adaptive Cruise Control can improve safety by maintaining a safe distance from the car in front of you.
Increased fuel economy
Since fuel consumption is greatest during acceleration, it stands to reason that the best way of achieving peak fuel economy would be to maintain a set speed. This can be quite difficult to achieve by way of standard pedal application. However, maintaining a set speed is easily achieved through the use of cruise control. However, in urban areas or congested roads with frequent stops and starts, cruise control may not provide the same level of fuel efficiency.
However, that’s not the case in vehicles that don’t have traction control, which includes most produced before it became mandatory in 2011. In those vehicles, the cruise control simply delivers more throttle when the wheels spin, resulting in a bad outcome for all involved. Whether gas is $5 per gallon or $2 per gallon, there’s no reason to waste any of it with all of the advanced technology at our disposal. Auto stop-start, cylinder deactivation, fuel injection, and electronic ignition all work together to provide a measurable increase in fuel efficiency. The first rudimentary versions of cruise control appeared in the late 19th century, but the modern version was invented in the 1940s by Ralph Teetor, a blind mechanical engineer. His goal was to stop the jerky speed adjustments made by his chauffeur, which led to the invention of “Speedostat”, later known as cruise control.
Cruise Control in Different Weathers
He's dad to a son and daughter, and plays rude guitar in a garage band in Worcester, Massachusetts. There are times when cruise control, adaptive or otherwise, is ineffective, and it can actually be dangerous in some circumstances. Anything above that starts to deplete a car's efficiency, De Haan said. Your mileage may improve by up to 2%, however, if you use the manufacturer's recommended grade of motor oil.

Cruise control safety tips
On the other hand, overinflated tires can lead to decreased traction and uneven wear. Drivers should avoid cruise control entirely in bad weather, including rain, sleet, and snow, but the reasoning for this is often muddy. A Google search will result in a whole lot of uninformed opinion based on flimsy understanding of how cruise control actually works in a modern vehicle. During World War II, when gas was rationed and the national speed limit dropped to 35, there was a flurry of activity from inventors looking to maintain a constant speed automatically.
Cruise control is generally good for your engine when used appropriately. It maintains a steady speed, reducing strain and enhancing fuel efficiency. However, avoid using it in hilly terrains or heavy traffic, as constant speed adjustments may lead to increased engine stress and decreased overall efficiency.
There’s no sudden pressure on the throttle caused by accelerations which could trigger more fuel injection. Your engine will keep operating in the set RPM range, and the torque range remains the same which results in less fuel spent. Utilizes the same sensors to boost safety features, including lane-keeping and automated braking. These features are particularly helpful in maintaining vehicle control and reducing the likelihood of collisions. The actuator — a key component — connects to the throttle pedal linkage and manages engine power to maintain a steady speed. It’s an elegant symphony between the accelerator, throttle, and speed control, all to keep our ride smooth and consistent.
Allowing the computer to make decisions means that you’ll likely have a more fuel-efficient outcome. If you’ve ever contemplated which grade of gasoline to put in your tank, you’re not alone. Learn more about octane ratings and what they mean for your engine.
The main reason cruise control saves you money on gas is one of consistency. Cruise control maintains a constant speed without need for constant pressure on the accelerator. When old cruise control systems accelerated back up to the required speed when you pressed “resume,” they basically floored the gas until the car got back to the required speed. This aggressive acceleration used a fair amount of gas, so modern systems accelerate in a slower, smoother, and more controlled manner that’s considerably more frugal. Adaptive cruise uses radar sensors to identify other vehicles and detect the speed they are traveling at. Let’s say your adaptive cruise is keeping you at that 50 mph on an open highway, but you then start to come upon some slow-moving traffic ahead.
And if the grade is steep enough, the engine will eventually stall. In the hills, it attempts to maintain speed and may over accelerate. Thus in hills accelerating a bit before the hill, slowing, and coasting down the other side tends to be more fuel-efficient than attempting to maintain speed. The primary purpose of cruise control is to level out the speed of a vehicle and give drivers a reprieve from pressing the gas pedal on long journeys. Cruise control is beneficial when you’re traveling in your car, truck, or RV.
