Does Driving in Neutral Save Fuel?

Driving in neutral does not necessarily save fuel, and in some cases, it can even be unsafe and is generally not recommended. Here's why:

Fuel Injection Cut-off:

Modern vehicles are equipped with fuel injection systems that automatically cut off fuel delivery to the engine when the accelerator is released, and the vehicle is coasting in gear (engine braking). This means that when you lift off the accelerator while in gear, the engine receives minimal or no fuel, resulting in fuel savings.
Coasting in Neutral:

When you coast in neutral, the engine has to idle to keep running. Idling consumes fuel, and in some cases, it can use more fuel than when the vehicle is in gear and the fuel injection is cut off.
Loss of Control:

Coasting in neutral means you lose some control over the vehicle, especially during emergency situations. In gear, engine braking assists in slowing down the vehicle, providing additional control and reducing the reliance on the brakes.
Engine Wear:

Frequent shifting between neutral and drive can increase wear and tear on the transmission components and may lead to additional maintenance costs.
Less Engine Braking:

Driving in neutral eliminates engine braking, which is a safety feature that helps slow down the vehicle without relying solely on the brakes. This can lead to increased brake wear.
Safety Concerns:

Driving in neutral can pose safety risks, especially in situations where you need to accelerate quickly or maneuver the vehicle. It's important to maintain control of the vehicle at all times.
If your goal is to maximize fuel efficiency, it's generally more effective to adopt fuel-saving driving habits such as maintaining a steady speed, avoiding rapid acceleration and deceleration, and ensuring your vehicle is properly maintained. Additionally, using cruise control on highways and reducing unnecessary idling can contribute to fuel savings.

Always follow the manufacturer's recommendations for driving and operating your specific vehicle. If you have a specific driving scenario or concern, feel free to ask!

If you know how modern engines work, you'd say no. But that depends on the situation.
Also, coasting down the road, you lose speed, and then you have to accelerate to get back up to speed, using more fuel. You'd be better off staying at one speed.
Another thing is that driving at higher speeds in neutral may cause transmission damage due to lack of fluid to bearings and clutches.

Well no, engine braking will always use more rpms depending on your speed, neutral disengages the engine to the transmission, so yes, you are saving fuel, not much, but it's definite.

I'm guessing if you are rolling down a hill it may save some. Due to lack of transmission drag you will roll a little further.

Yes, it depends who/how is driving, it’s all about timing,

I promise you're using less gas at the 300 RPM's neutral sets at. Than the 1.5k - 2k RPM's you're pressing on at

I don't understand. My 2015 Kia Soul has a nice "real time mpg" indicator and any time I coast for like 400m, it goes up 1 tenth (0.1 mpg)

I wouldn't save fuel while driving sport SUV like this G-Wagon😂😂😂😂

Dawg as long as it's a auto. Ride in neutral as much as u want

And he doesn't even explain why wow nice video 👎🏽😐
