I did the no no and topped off the tank. Thats good for 100 extra miles. Oh, and for those that are wondering. I have the ulev 13 gal tank.

 

Alright, that makes more sense. Thanks for pointing that out. I'm not a topper-offer.

 

I generaly don't top it off either. I just wanted that little extra for this attempt.

 

haha i'll be glad to make it to 600 miles on a tank i've never topped off a tank, never will. besides, i live close enough to gas stations that it isn't inconvenient to fill up..12-15 days at a time

 

Hey Tom-
you can do it! my gas light comes on at 2 bars and I've gone 25 miles after that and filled 10 gallons. I have the 11.8 gallon tank (pzev) so that means with 2 bars there's at least a gallon left. If you've got 4 bars- AND your tank holds more- you've got to have at least 2.5 gallons left
so go for it.
Myles & I are going for the first pzev 600 mile tank. ok- so it's not the first....but it will be a first for us! don't think I'm going to make it this tank though- I was doing really good till last week when it got cool again, and my mileage went back down to 49 from 54. bummer.

 

Speaking of topping off, I learned this about the Civic GX natural gas vehicle:

"If driven from LA to Washington DC, the GX would emit less pollution than spilling a teaspoon of gasoline on the ground."

Pretty amazing, huh?

Anyway, on the 700 mile thing - I have seen in my car that I usually have about 1.5 to 1.75 gallons left when the "low fuel indicator" comes on for the first time. So even taking a conservative number of 48 MPG, I believe I can get AT LEAST 72 more miles. Many times, my low fuel warning light will come on, then on a later driving session it will again turn off. I have two tanks over 700 MPG for far, with the 13.2 gallon tank !! Good Luck All !!!

 

Larry, are you a topper offer or do you just stop when it clicks.

 

I stop at first click, always, without fail.....Learned that a few years ago when I read that the EPA and other recommend never topping off.....

 

I think you will do it... the pucker factor will be high though!

Your MPG numbers are getting better and better, I would think you are driving more conservative than ever before.

Good luck with your personal challenge.

 

maybe i can do it this tank i'm at 200 miles and 51.4 average mpg, pumping tires from 42 psi to 44 psi this weekend. if anything, i'll make it to 550 miles !
