Is it OK to coast in neutral in a car?
It is fine to coast in an automatic in neutral as long as the engine is running. If you stop the engine completely and coast (as is often the case when being towed), you can damage the transmission.
How does coasting in neutral save you fuel?
So the argument that you’ll save fuel doesn’t work, because you won’t. See, many modern vehicles will, when the system detects the vehicle is coasting (no load being applied via the throttle), shut off fuel supply or in those with the technology deactivate cylinders to reduce the amount of fuel being consumed.
What happens when you coast to a stop in a car?
The reason is that the ECU/TCU is programmed to detect situations in which the wheels are driving the engine (e.g. when downhill or coasting to a stop) and to shut off the fuel injectors, hence zero fuel consumption. If you switch to N, some fuel has to be used to keep the engine idling.
What happens when you put your car in neutral when driving down a hill?
Unfortunately, it doesn’t work like this for vehicles. See, when you take either your manual or automatic out of gear and into Neutral when driving down a hill you end up using, at the minimum, the same amount of fuel and perhaps more because the engine is still working and the fuel is still flowing.
Why do you put your car in neutral when coasting?
It’s unsafe. You need to be able to use the accelerator to avoid an unexpected road hazard; cars don’t handle well in neutral during sharp cornering maneuvers when the engine isn’t connected to the drivetrain. So why on earth would you put the transmission in neutral—whether on manual or automatic—when coasting?

When to put your car in neutral to save gas?
That usually starts at around 1000 rpm, and if you pay attention, you can sense when it’s happening as the engine will rev up slightly. And that’s when the scan tool or oscilloscope will show injector dwell rise from 0 to 5 to 10 percent. So you’re actually wasting gas by putting your car into neutral.
Is it bad to coast to a stop sign in neutral?
Coasting in neutral is dangerous and it burns up more fuel. Here’s why. I get mail. I’ve said, on the record, many times, that it’s a bad idea to coast downhill or up to a stop sign in neutral. It’s unsafe.
