This was at the gas station. I was able to fill with 10.4 gallons. Could have come close to 600 miles!
You'll never be satisfied, it'll be 600, then 650, hehe. I'm at the other end of the spectrum: if the gauge is anywhere below half, if I see my favourite brand, I'm tanking up. Helps that we're low consumers, this is every 3~4 weeks.
True, but likely only about 1 gal usable remaining. When the last pip goes out you want to be close to a station. If you wanna hit 600mi for a tank you need to see the indicated average close to 56-57. Good luck with that.
I NEVER recommend that anyone PUSH the envelope as far as running the gas low on a Prius, or any vehicle for that matter. But I would say, that a Good/Bad thing about Prius ownership is filling up and realizing you really COULD of gone a whole lot further. At least with MY Prius I find the gauge, the warnings, all to be very conservative. Which probably IS a good thing. Because as much "fun" as it might be to go as far as possible on a tank? Running out of gas is both potentially damaging and dangerous. So I try to take some enjoyment out of appreciating how far I have driven, and the fact that I had more left in the tank than I thought. I'd rather fill up a little early, than fill up a little late. Gas cans and long walks aren't fun. Losing power while driving is dangerous.
My main motivation for filling sooner: I'm logging fuel consumption tank by tank. Low tank increases odds someone else'll fill up, and that's when bad things happen. I can always salvage things, but I'd druther not have to.
This reminds me of a post a while back...(with lots of people jumping in about things not relevant)... All I said was "I could have come close" to 600 miles. Thanks to many of the posters who have once again reminded me what a wonderful place this is.
