Default MPG conversation continuant from dude's welcome thread

If you're worried about fuel economy find a big rig and cruise behind him. Less drag=more MPG.

I think I hit 50 MPG one time

Say what you will but it's true. Hugged the semi for a bit doing 65-70, reset the calculator and first number it hit was 50.

Here's a simple comparison,

A student has gotten the following grades on his tests: 87, 95, 76, and 88.

Does this mean that the 95 never existed because his mean(average) is 86.5?

I cannot seem to get the last comment by F3ARL355 I think

Nice making the new thread.

Averages and students mean nothing. You are in a diploma level course: you get 100% on one exam worth 25% of your final grade, and choose to not complete anything else for the rest of the semester. When presenting your grades to a college/university, they then look at the 25% average you obtained. They don't care if you got 100% in one instance; the average tells a trend. The point is, the 100% is still there but it really doesn't tell anything about a student's ability.

I'm not saying it didn't happen, but having 50MPG for a split second does not mean anything. Do the calculations with how far you travel and the amount of fuel you used. That is how you figure out gas mileage.

How did you verify the flatness of the pavement and account for external forces like wind? Let me guess, you didn't. Is it so difficult to believe that you pressed reset on a segment of the road with a slight downgrade so that the car needed little to no fuel to maintain it's speed, there by enhancing and at the same time clouding the effects of the truck in front of you? Sounds to me like nothing more than a crude experiment with no control.

This was done on mythbusters anyway with a car averaging just over 30mpg at highway speeds without following a truck. At a distance of 10 feet behind the truck, it didn't even reach 45mpg. I'm willing to bet you weren't any closer than 10 feet, so you should just chalk it up as several factors coming into play. Particularly the fact that you were traveling downhill.

I hit 99 mpg. i don't understand what the big deal is. Find a long hill, put car in neutral to coast down and reset the MPG. 30 second later it will show 99.

At what point did I ever say anything about a downhill slope. You're putting words in my mouth.

Let me guess, you used this site http://green.autoblog.com/2007/10/28...-improve-mile/ to find the mythbuster information?

That's exactly what I was getting at! You can get the computer to show a crazy number, but it doesn't mean it's an accurate representation of your gas mileage. You don't go around saying your car gets 99MPG because the computer flashed the number for a few seconds.

He was saying you could have been on a slight downgrade and not known it. You could have thought you were on a flat segment but were actually going downhill.

I actually saw the episode but yes I used that website to reference the correct numbers. So what's you're point?

That is true. Over a length of time you will get a more accurate average reading. 50 MPG as an average is generally unobtainable with this car unless you drive like this guy

What I did obtain however was a current economy of 50 MPG for a short period of time. I know our computers give us average but that first number you receive is gonna be most accurate to your current MPG, which mine at that time was close to 50. Edit: I was able to hold that high number for a bit of time. Although it wasn't 50 I was A LOT higher than average. Distance unknown

I should have specified here about what I was saying to the OP. Current vs. Average. That I apologize

Just want to make sure you're not googling your points to find something that supports your claim. I don't really watch "Myth Busters" anywho.

Worried about fuel economy < getting road debris chucked at my car, not being able to see what's beyond the big rig and/or getting decapitated when he slams on his brakes while I'm playing Angry Birds.

Who cares what MPG you can hit for one instant?

Speed up to 155, put car in neutral, reset computer... World record MPGs!!!

Seriously? WTF is the point of this thread? Getting 50 MPG over the course of consuming one ounce of fuel means absolutely nothing. The trip computer is good only for those who are totally incapable of dividing miles since the last fill-up by the gallons pumped at the next fill-up. What is it about this that leads to so many pointless threads?

^^yes because its the final grade that matters! so 95 is not an accurate representation of his mark....

I achieved this while traveling across the skyway bridge in tampa/stpete. I reached the top then put it in neutral reset computer at 75mph and coasted till i hit the bottom.
