    No, I've heard too many stories of folks "topping off" their tanks which can risk getting gasoline inside the charcoal canister...and it's not cheap getting that replaced.

    I estimate the amount of gas she needs (like 7 gallons) and will turn the auto-fill level from "fast" to "slow" at around 5 gallons to finish it up. Once it clicks, that's it.

    Just a one time thing to see how much gas there is from auto shutoff to overflowing.

    Do you know? If so you can save me the trouble.

    @VelvetFoot - a thought just occurred to me - you seem to be getting what I consider to be stellar (at or above EPA estimates) fuel efficiency all things considered (winter in New York). I also remember seeing posts from you mentioning removing the plastic wheel covers and installing wheel center caps sourced from Amazon.

    So - the mpg's you've observed to date - are all those with the plastic aero-wheel covers off? And I "assume" some mix of city/hwy driving?

    I ask because, my daughter in southern California is in the camp of those that don't like the looks of the plastic wheel covers (her comment is "makes it look like a Tesla"), and she prefers the look of the alloy wheels 'hidden' under the wheel covers. I earlier told her that after I drive her LE from Louisiana to Socal I could remove her wheel covers if she wanted but that she might experience a slight drop in overall mpg's. [I shamelessly stole your idea and ordered the exact same wheel center caps off Amazon that you did and also verified they fit, so ready for exposing the alloys].

    So I'd love to be able to tell her it's at least possible from your experience to get at/close to EPA mpg's even with the wheel covers off - but want to make sure that's what you're actually doing.

    @Probity , I never removed the wheel covers, except to put on the center caps.
    That must've been somebody else.
    I like the look of the wheel covers.
    One COULD be of the opinion that it makes the rotors appear less tiny, which is also a thing, apparently.. :)

    Tangentially, I recently got the oil changed by the dealer and they may have put in 0W16 instead of 0W8.
    I think I'm getting less mpgs.
    Hard to prove though. :)
