I have a gas station down the street from where I work. When I pulled into work, it was on e, the light had been on for a while, but I was running late. i had no choice but to park it in one of the dozens of parking spots I normally park in.
Come lunch hour, I started the car, on E (it couldn't go any further) and let it idle while cleaning off the car, then casually drove it to the gas station, and filled it. It normally never goes down past 3/4 a tank. But still, I've had a job at a ford dealership before. Lots of cars will remain running for quite a few miles past empty.
Ever watch Seinfeld? It's true.
Mind you, if you have some freaky fuel guage and end up stranded somewhere, don't take my word for it.
My story, however, of what happened to me today is true
I think it actually takes a lot more to start the car.
I am probably wrong, but i do think that the reason i get crap MPG (18mpg city, 25 highway) is because i usually start the car like 5-6times a day.
I don't know about 2.3 cause I have a 2.0, but when the E light comes on and I fill up righ away, its usually about 12 gallons. Our tanks are about 14.5 gallons, so your 3 is drinking gas like crazy if you can only do 15 miles on 2.5 gallons. On one highway trip I did about 55 miles on E and when I filled up it was about 13.5 gallons, so I still had plenty left. However I don't do it often, as road conditions may change an you can get stranded, especially in winter.
The point is you can do a lot more than 15 miles when E light comes on.
As far us starting the engine I think that only cold start-ups use more gas, as the engin is in open-loop. When the engine is fully warm the RPM jumps to 1700 for a second or shorter, and come down to 700 ( at least on my car), so if you think youre gonna idle for more than a minute and you want to save gas shut down your engine.
Hybrids do shut down the engine when you are at a complete stop, when you lift your foot of the brake, the engine starts automatically, and they would not do that if this method wasted gas. Now freaquent startups will put extra wear on your starter, so I use better judgement. Sometimes it is better just to let the car idle if it is really a short stop.
It's true, the gas light comes on between 11.5 and 12 gallons, so you should have between 2.5 and 3 gallons left. That is at least 60-90 miles of driving at 30mpg and for the sake of argument, thats still 50 miles if you get less than 30mpg.
this is great and all but how hell did we get to talking about how much gas is left when the light comes on?
Oh I see, it was Evil dead fan with his awesome story. But yeah, the light coming on shouldn't make you freak out. I've gone to school and back with the light on, and I live pretty far from school. They should have made it so it turns red when you only have like 10 miles left.
