I am so curious as to how much gas is wasted when people sit for endless amounts of time in different drive-thru's!

I live in a small town and every morning I see an endless amount of cars sitting in the local McDonalds Drive -Thru! Sometimes there are as many as 35 cars, they actually line out onto the street!

need a mathematician to help me with this one haha!

God Bless! TOL!

HERE GOES:
:
3,000 calories a meal, divided by 15 minute wait equals 200 calories per minute, divided by 60 minutes/per gallon @ idle speed,= 1/4 gallon wasted to get fat!
:
Hope this helps, so try to eat at home, you'll save gas and your health.

Just think of all that junk food they are eating. That's the real waste of money.

All of it. I never use the drive thru windows. Park and go in. It's usually faster, and easier to make sure they didn't screw up your order.

Hi dontuknow and cheap2010skate, I wasn't inquiring about an actual total, I just was looking for somewhat of an overall estimate , but thanks for your comments! Hope you all have a great weekend and gee you got some points for answering haha!

dontuknow, that's great comment on them needing to buy a whole street! Love it! Plus the stock, I have thought that for years!

God Bless! TOL!

cheap2010skate; I would agree with your last sentence,on this post,even if it were possible that every vehicle on the lot had a gps databank recepter montoring all vehicles running,the difficulty is enormous!Sorry!

Counting raindrops on the windshield is easier Ha. LOL

I never use drive-thru's. I can't imagine how you would figure out the cost of wasted gas. You would need to know the type of car, how old the car is, how long they waited, how many days, how many times per day, etc. If you expend this much time and energy on calculation, it might be best to devote your time to something else.

frequently restarting and shutting down the car is bad for the car

Some newer cars are starting to have automatic shut off/restart when a car sits at idle at a slow light, railroad crossing and drive through lines. My guess is that the amount of gas saved will be a big part of their ads.

From what I have read modern cars burn about 1/4 to 1/2 gallon of fuel per hour at idle. Since every engine is different you will have to take the differences into consideration. Bigger engines burn more fuel and smaller ones less. So take the average number of minutes sitting idling divide by 60 and multiply by 1/4 for the minimum and multiply by 1/2 for the maximum and you will have two figures that probably will give you an idea of the fuel usage.

I used to have an old IHC van that burned about 1 gallon of gas per hour at idle and it was probably running well at the time. I was lucky to get 15 mpg with it on the highway. I knew this by an early mileage computer that I had fitted to the truck. It was most instructive.

So some cars will burn more than the 1/4-1/2 gallons per hour but that is a start.

The only drive-thru I use is at the bank. I use it about once every three weeks and usually there are no cars ahead of me.

"Mertieman" I agree about the lights that hold for ever! I live in a small town so our lights are synchronized very well thankfully, but I sure remember when I lived in SO. CA. and sitting waiting for a light to change!

I very seldom use a drive through unless one is totally empty. You waste money in this area waiting on red lights that hold for 3 minutes each.

Look at it this way,that extra engine heat keeps the parking lot warm,so if in winter you might choose to stop in your footing will be secure and not slip on adverse weather pavement. The USG needs extra gas tax revenue,to recover,Hungry people help out greatly dontuknow? HaHa! GOD is Blessing! The Experts say More in Less out is the Solution So drop in Line.. You Welcom!

The fuel consumption rate at idle varies from car to car. I've seen fuel consumption rates at idle range from nearly 0.8 GPH to around 0.1 GPH. There are macro reports/studies done on aggregate idle time costs that you can research.
