2010 Toyota Prius: First Drive Never mind Tony, I saw that you linked to it in the thread that chenderson2 posted. Unfortunately, that article is gone but your quote is still there. How low can I get my fuel economy to go? | PriusChat
Low Fuel Light came on this morning on the way to work at 616 miles. DTE was at 21 miles. WIthin a couple of minutes, the DTE went to ___ and the car posted a message in the MFD asking me if I would like to look for a nearby gas station. I will buy gas today at lunch approximately 650 miles driven on the first tank of gas. Will post stats after that fillup.
I have averaged (by car's calculation) 64.8 MPG on this first tank. That tells me that there should be a gallon in reserve. The wild card is the dealer's definition of a "full tank" on delivery.
LIfetime calculated MPG 50.2 Lifetime computer MPG 52.0 Seven tanks above 60 MPG (out of 267 opportunities)
The times I pushed it, I wasn't on the dealer's fill, but on my own fills after figuring how much refill the car took at various low markings. And I had a spare gallon with me. From one of your previous posts, and from the newly blanked out DTE display, this sounds like it could turn out like my 2014 Subaru. Its DTE has zero safety margin, and is blanked out after dropping to 30 miles. But there are enough other earlier low fuel warnings, far brighter and colorful than in my G3, that drivers have no basis to complain about running out.
Winter-only numbers: 64 tanks Computer Average MPG 50.7 Calculated Average MPG 48.8 Definitely some lower than the all-up numbers
Winter is subtle, but it does make a difference... First Fillup Data: 650 miles. (gas warning light came on at 616) 10.211 gallons of regular gasoline (off at first click) 63.66 calculated MPG 64,9 MFD MPG
Thanks for the report, astounding mpg, and not far off the displayed mpg: 2% error is much better than 3rd gen shenanigans. That empty gas gauge scares me. According to the manual the gas tank capacity is 11.4 US gallon. I'd guess that is not up to the neck, but who knows. I think you came pretty close to running dry, I'd play it safer next time there's no upside to that game.
I'm brave / foolish enough to do that in benign conditions after a few tanks, but most certainly not on the first one.
Now I see Toyota's game...get some good MPG results in the balmy California sunshine before the snow belt buyers mess up the Fuelly numbers. 69F? You gotta be kiddin me.
