Honda Civic Real World MPG

Replying to: sebring95 (Dec 06, 2007 1:38 pm)

Unfortunately, I only had a $10 bill [doesn't go far nowadays, eh?] so I did not get the exact full tank re-fill numbers...OTOH, the '03 civic almost always had the light on at 380-390 like clockwork and got a consistent 42-43 mpg 68-70 mph...so, I should have gotten in the 40 mpg plus range at least....I am guessing the 'drive to nothing' range is about 510-525 range....intersting this is the best I could get in a honda fit which could be filled up in the long neck to about 12 gal. or so...it would get 43-45 mpg over the same roads...I would think the civic at 55 mph with the 5 AT should do the same.....??

"I understand, but essentially that renders your original question unanswerable."
 
Well, to be more specific what is important is estimating how far the civic will go before running out of gas when the "E" light comes on. I have no accurate way of telling if 13.2 gal is actually in the tank the way I fill, nor if it varies much for different pumps. Actually unless the driving conditions are unusual I can expect 400 miles between refills without problems.
 
Gas stations can be few and far between, but not much city driving so at over 8000 miles I am averaging over 40 mpg since new.

"I guess the safe range to refuel is 400-450 range"
 
With over 50 years of driving, I've found the safest range is when the needle gets to the 1/4 tank mark.
 
People have gotten stranded figuring that out!

I'm trying to figure out how you came to that conclusion.
 
FWIW, even though my wife and I have only been driving for 35 years each, we've covered over a million and a half miles combined. Couple that with the fact that I used to be a professional wrench and worked on MANY cars and I think I might have some empirical observations to offer in this discussion as well.
 
So, what do I think about the quarter of a tank recommendation? Way too conservative. I've never seen any scientific or empirical evidence that suggests that driving a modern car (with an in-tank fuel pump) down to the "E" mark will harm anything in a car. Yes, yes, I've heard all of the arguements about picking up debris from the bottom of the tank and about needing to cool electric fuel pumps with the gasoline, however, virtually every car on the road these days has enough of a reserve capacity beyond "E" to cover those issues.
 
My advice? Drive the car until you show "E" and then fill'er up. The only exception to this rule that I follow is when I'm heading out on a long trip (where I fill up almost regardless of how much fuel is in the tank), or when there is a question of fuel availability (kind of a "bird in hand..." scenario).
 
Best Regards,
Shipo

Essentially I do what you do. While the Civic does get good fuel mileage, on the down side one can indeed get 40-42 mpg (better or worse obviously) and get ranges of 560-588 miles or so, You can STILL run out of fuel, if you are not calculating on most probable data.
 
Since I have a diesel, even on longer trips passing into some of America's remote deserts, it is a no brainer to let it go till the fuel lamp and buzzer goes off, as I know from several data sources there is at least 2.4 gals or app 100-142 miles to go. Depending on how one drives the range can be from 700-826 miles.
 
I also am mindful of the 1/4 tank metric, especially on my SUV in the snow. I have been on those snow trips that are supposed to take 3.5 hours and wind up taking 10 hours. Naturally EVERYONE else is running out of fuel as I am....Of course you line up at the only mountain fuel station for miles around and get into line and think lets head to the restroom,... which is already 43 folks deep.
 
Reminds me of a filling stop I made once on the way to San Diego, CA. The attendant came out of literally an old 1950's style room and insisted on pumping the gas. Since he was going to monitor the process I asked where his rest room was. He sort of hesitated and then the lights came on and pointed in the direction and said the odd house was over there. Sure enough when I went in it WAS an odd house. I was half way expecting Rod Sterling to surface and announce the next episode of the Twillight ZONE!!
