With summer hitting the US soon lets look at different methods of cooling when thinking about cost of running.
Using Air conditioning does burn more gas, especially when driving in the city. Fuel consumption can go up by approximately 10%.
However it has been also noted that air conditioning saves on gas because it removes air drag caused from the open windows. This usually occurs when driving at speeds greater then 45 mph / 72 kmh. It can loose fuel efficiency by as much as 10%.
So a good rule of thumb to follow is when the car is moving at a rate of 45 mph / 72 kmh or slower, driving with the windows down is definitely the better option for fuel efficiency. That means that for trips to the grocery store, post offices, and visiting ma and pa, drive with the windows down. When town driving, leave the windows open, when highway or higher speeds driving, the AC is definitely the way to go.
Some other tips to help keep you cool this summer:
- Use the fan on the highest setting when to quickly cool the car down.
- Park in a garage or shaded area.
- Use windshield shades to help keep it cool
- Leave windows open (if in a safe area)
- When using air condition, recycle inside area as it should be cooler then outside.
