First time after more than three years, I filled up my gas tank today and it's only nine bars? I always fill it up when the last bar starts blinking with beep: it's been around 8.2 gls - 8.4gls every time and today is not different. Is it easy to fix? I don't want to start keeping track of the odometer when the gas gauge is not accurate anymore.
that happens to me once in a while as well. sometimes it goes to 10 after a little driving, but not always.
I've noticed similar behaviour with the ChuggyPig, (to the OP) don't agonise too much about it, I expect your odometer is accurate, at least consistent, so the gauge on the gas-pump must be accurate (it's the Law!) so keeping a log over time sounds like your best plan, and at least it will be accurate! hope this helps - Wil merged Also: Check out the downloadable User-Guide to see what it says about running out of gas (p.20) https://attachments.priuschat.com/attachment-files/2015/10/95919_Prius_User-Guide_iconic.pdf - Thanks Ron!
