can you drive your car in neutral

[ORebecca]

No, you should not drive your car in neutral. While it is technically possible to coast in neutral, it is a dangerous and inefficient practice that offers no benefits for modern fuel-injected vehicles and significantly reduces your control over the car. The primary risk is the loss of engine braking, which is the natural resistance provided by the engine when you release the accelerator in gear. This resistance helps slow the car down and is a critical safety feature, especially when going downhill. Without it, you place excessive strain on your braking system, which can lead to brake fade—a dangerous condition where brakes overheat and lose effectiveness.

Furthermore, driving in neutral in an automatic transmission can lead to improper lubrication. The transmission pump, which circulates fluid to cool and lubricate the gears, is often driven by the engine's input. At highway speeds, if the transmission is in neutral, the pump may not operate correctly, potentially causing premature wear or damage over time. For manual transmissions, the act of shifting into neutral while moving is less harmful but still eliminates engine braking and control.

The idea that coasting in neutral saves gas is a myth for cars built after the 1980s. Modern engines with electronic fuel injection (EFI) are designed to cut off fuel flow almost completely when you are decelerating in gear with your foot off the accelerator. In contrast, when in neutral, the engine must use fuel to idle, meaning you're actually burning more gas while coasting.

Scenario	In Gear (Drive)	In Neutral
Engine Braking	Available, aids control	Lost, increases brake wear
Fuel Efficiency	High (fuel cut-off on deceleration)	Lower (engine idles, consuming fuel)
Transmission Health	Optimal lubrication and cooling	Risk of inadequate lubrication (automatics)
Overall Safety	Maximum control and responsiveness	Reduced control, delayed acceleration

In short, the safest and most efficient way to drive is to keep your car in gear until you need to come to a complete stop.

It's a bad habit. I tried it once on a long downhill to "save gas," and it felt sketchy. The car started picking up speed way too easily, and I had to ride the brakes the whole time. My mechanic buddy later chewed me out, explaining that I was cooking my brakes and that modern cars actually use less fuel when you just leave it in gear. You have less control—if you need to accelerate quickly to avoid something, you're fumbling to get back into drive. Just don't do it.

From a pure mechanics standpoint, the vehicle will roll, but control is severely compromised. The principal hazard is the elimination of engine braking, transferring 100% of the deceleration duty to the friction brakes. This can cause overheating, especially on declines. For automatic transmissions, there's a secondary risk of insufficient lubrication at high wheel speeds. The practice provides no mechanical advantage and introduces significant safety and maintenance downsides.

Think of it like this: your car's engine is a built-in helper for slowing down. When you're in gear and let off the gas, it helps you brake gently. Putting it in neutral disconnects that helper. Now, all the work is on your physical brakes, which can wear out faster and even fail if they get too hot on a steep hill. It’s also a safety thing. If a kid runs into the street, that split-second it takes to shift back into gear could be the difference. It’s just not worth the risk.
