Ok I did it finally!! I went 513 miles in one tank of gas! I have been trying to do this every since I purchased my '01 Prius last November.

I purchased my wonderful car used over Ebay, got a great dead but I had to drive it back from CO to OH, oh no big deal, I guess the only way to get use to the car. :lol:

I broke the 500 mile barrier during the month of March in Ohio, when it was hovering about 60 to 75 degrees for about 2 weeks. Those comfortable temps really do make a difference to the batteries.

When I filled the tank I pumped in about 11.3 gallons and manually estimated the mileage to be about 45.4, the computer estimated the mileage to be 51.6, which is not to comforting to see that big of a descrepency.

Most of my driving is done in the city-secondary roads, sub 45 MPH, One time before taking a highway trip, after only about 155.1 miles I filled up my tank, the computer said I was getting 57.2 MPG and I manually computed the mileage to be 59.5, I added a wopping 2.605 gallons. That amount was after the 3rd or 4th click of the gas pump saying the tank was full, so I squezed in a little more.WOOHOO! That made my day.

I hope other people are having good results as I am with my prius.

Regards,

Jason- Dayton, OH -- '01 Silver Prius

Re: 500+ Miles in 1 tank

Hi Jason,
I managed to get 500+ miles per tank of gas three times last summer. Two of the times were unintentional as I was not paying attention to the gas gauge or the trip odometer until the chime went off and the last bar started to flash. The best was 523 miles. I still had one bar left on the gauge, but I decided not to take a chance. The car took 11.2 gallons of gas after that so there was not much left to play with!

As to the difference between the computer and your calculated mpg for one filling, that is normal. The computer is usually a bit on the optimistic side, but the problem is that each fillup does not fill the tank to the same exact level. If you compare the computer's figure to your calculated figure for three or four fillings, you should see that they are a lot closer.

Good luck with your car!

Oh ok Thanks!

I tend to notice the most acurate mileage is on the first click of the gas pump shutting off, usually at that amount is the closest to the computer estimatd compared to how much you can physically get into the tank. But we know that the prius has a bladder in the tank that affects the amount of fuel that goes into it. So this can throw the whole thing off.

Im going to try again, now since it is warmer I should be able to easily break that mileage on 1 tank.

Use caution overfilling that bladder! It will expand. Others have reported pulling out the gas pump nozzle only to get fuel spewing forth all over the place. Very un-fun.

Now, just to add the jealousy factor, I will report that I always stop pumping on the first click. And, here in Houston, where the temperature is nice and warm most of the time, I regularly get more than 500 miles to a tank. I will have to actually look at this fill up ('cause I am having a good tank) and see how far I get.

 

[Sterling_Aug]

My maximum mileage so far is 518 miles on a tank.

Right now (since the weather is warmer here in PA) I am at 498 miles on this tank and the 10 gallon used warning light did not even turn on yet.

My MPG went way up since I increased the tire air pressures up to 43-40.

 

[tdonoughue]

Well, unfortunately, I had to do some poor driving at the end of my tank and only wound up at 498. <sigh> Figures.

I keep my tires at 47.5. I think it works very well. The ride is slightly stiffer, but I prefer that feel in the suspension. Tire wear is much better and the gas mileage is very nice. No significant change in breaking/wet weather handling.

I have tried them at several different pressures. Much more than 47 doesn't seem to affect mileage that much for me. But the difference between even 42 and 47 is notable.

You do have to be careful, because if your dealer is like mine, when you bring the car in for the complimentary service and they rotate the tires, despite all instruction, they will put them back to 35...

560 miles on tank

Ok, I did it again, I broke the 500 mile barrier. I went 560 miles on a tank of gas! When I filled it was just under 10 gallons, the weather got colder here in OH, so I was not able to get the full tank on warm weather.

If the weather holds out I will be attempting to break the 600 miles.

Dont try this at home kids!

Don't try this too far from a gas station either!

616 miles on my tank

I broke 616 miles on my last tank of gas. I had 575 miles with 3 bars left. Two of the last bars really shut off quickly leaving the last bar, but no warning signal. I didnt take anymore chances on pushing this last bar. But can say I broke the 600 mile mark. I was averaging 58.4 mpg.

Re: 560 miles on tank

I actually ran out of gas on the freeway; I was trying to push it to see how far I could go. What ended up happening was the battery kicked in full bore, as I coasted to the exit. The "red triangle of death" simple illuminated the LCD, and no other functions were available (couldn't change the radio station ). I got to the gas station one block after the ramp.

After I filled it up, it was back to normal. I don't plan on letting this happen again (it can't be good for the 'lectric motor to kick in at 65 mph), but it is comforting to know that in a pinch the poor thing won't come to a dead stop on the beltway

Broke 600 miles in tank...

Hello everyone,
I did it, like I said I would attempt, I attand 615 miles in a tank of gas!!

The first click of the gas tank was about 10.3 gallons and then I was able to squeeze in another gallon, so I roughly got about 58 MPG!!
I love this car!

This is the farthest I will go on the tank before I need to fill up. I drive only city and do not use the A/C, well this will be the first summer that I have had the car so I do not know what will happen, will try to not break down and use it... :?

The 2004 Prius should be able to definately go further on a tank of gas.. That will be interesting to see how far 1 can go in it.

You guys are using regular 87 octane pump fuel right?

 

[Jason]

Of course, that is what Toyota says to put in, the engine is design for 87 octane only.
