Can I leave my car running while I sleep in it?

Can I leave my car running while I sleep in it? No! Do not do it. If you take a nap in your car with all the windows closed and the AC running, there is an increased risk that the same air will be recycled inside the vehicle, and fumes from the engine will make their way into the car through the cabin.

Is it better to idle in park or neutral?

Keeping an automatic transmission in Drive puts an extra load on it, which drains fuel. In neutral, it’s resting — or at least as close to rest as an automatic ever gets. This shift is even more important when the air conditioner is running, so the engine doesn’t have to strain so hard while idling.

Is a Ford Focus a low emission vehicle?

Alternatively, the 2.0-litre diesel engine emits 105g/km of CO2. If you are looking for a petrol car, the cleanest engine is the 1.6-litre engine which emits 110g/km.

Is it better to keep an old car or buy a new one?

The “50 Percent” Rule. On a purely pragmatic basis, it’s almost always cheaper to keep an existing car running than to purchase a new one. If a car looks good and has been maintained meticulously, having a mechanical problem fixed now might prolong its life for tens of thousands of miles down the road.
