most miles on a tank of gas?

[bagwell]

aside from testers going 41 mph for 2 months straight and getting 150mpg and 1000+ miles on a tank of gas, what are some of the highest miles (NOT MPG) people have seen on one tank of gas?

I topped my insight off completely when I filled up last month and currently have 816 miles on my tank of gas....just under a 1/4 of a tank left.

Most people myself inculded won't run the car until the tank is dry and it stops!

It's asking for trouble, so it's difficult to say when it's really empty.

If people run it until the fuel light comes on and there are no bars on the gauge there could be 1L of 5L left who knows All are likely to be slightly different and likewise will give different miles per tank.

It's a tough one unles you try to use a measured quantity instead.

....Over the years, on all 3 of my Insights, I have done this test, with the exact same result. Carry a small, 1-gallon gas can in the back. Purposely run out of fuel----and turn the engine off just as soon as you feel it miss or sputter; that way the fuel pump & fuel injection is not completely dry, so it will restart easily. This same test is very important on airplanes, and I used it often when testing different aircraft back in the 1980's. It's extremely valuable to "calibrate" the fuel gauge. Many small planes have 2 or more tanks, with a valve handle to switch between them. I would fly along and quickly switch tanks when the engine sputtered, and note the exact position of the fuel gauge. Of course, these tests were done at ample altitude, with an airport within gliding distance.

After ALL THE BARS on the fuel gauge are gone, one can drive aprox 65 miles (5 speed model). (I estimate 0.8 gallons remain) Usually the low fuel warning light comes on with one bar left. At that point, I can drive about 130 miles.

To answer the original question, I have gone 1116 miles on one tank (10.76 gallons). And one time when I really filled the tank full using the "fill up all the pipes" technique (13.08 gallons) I drove 1344 miles!

I wasn't asking about running it out of gas, just wanted to see how far "normal" people can stretch out a tank before refilling.

Billy -- good post thanks! BTW that's a helluva LMPG !!!!!!!

I shoot for 700. Last tank was 775 miles, 10.18 gallons of Amoco Ultimate Gold. I drove around 50 miles with no bars on the gas gauge. Last three tanks have been around 75 mpg. I have not ran out of gas yet.

i usually fill up with one or 2 bars left on the guage...and get about 600-700 mi on the tank

but my mpg is NOTHING compared to some of the others here

though i am working on it , right now my LMPG is 57.8(bought it used w/ 94k mi)...my OMPG is about 58 or so...but increasing...ive been doing alot of 70+mpg trips recently

I routinely fill at over 1000 miles in the winter, and more than that in the summer. My lifetime best was just over 1200-something at round 12.5 gallons or so at the end of last summer.

On my car, the last bar disappears with exactly 1.1 gallons, but I'm sure everyone's vehicle is different.

For non-hypermilers, I would say trying to drive more than 40 miles after the last bar disappears is playing russian roulette.

Actually it was an average of 18 MPH for 9 days. The record stands at 2254 miles on 13.7 gallons, but you are right that is not "real world" driving. I belive the "real world" record is still held by Randall Berkholder at 1534 miles followed by Wayne Gerdes at 1526 miles, then me at 1520 miles. Wayne was the first to do a 1500+ tank, then Randall and I did one when we were practicing for the Insight marathon. Mine was half P&G and half normal daily commute. I have filled my car 123 times and have averaged 846 mile tanks. I have 20 1000+ mile tanks, 8 1100+ mile tanks, 2 1200+ mile tanks and then my personal best of 1520.

A good way to judge your range is to take your current tank average displayed on the FCD and multiply it by 10, unless you over filled the tank last time, then multiply it by how ever much you put in. On my car the half full mark is more like 1/4 full and should be good for + or - 200 miles.....Louis

My best is in my signature.

I ran my car to 1000 miles ONCE, but never again.

Too stressful!
