    Is your onboard gauge less "off" that the Scangauge after you apply your correction factor? As best I can tell, the Prius cumulative mpg readout is very consistently off by the 0.956 factor Edwin mentioned. Scanguage fuel consumption data is next to worthless, because it is so inconsistent; it can not be calibrated per their instructions. I suspect that's mainly because it SOMEtimes counts phantom consumption when coasting above ~45 mph (the Prius equivalent of fuel-cut mode).

    Saturday morning went 3UP to an Achievement Event in Nottingham for youngest. We met Nic Hamilton (Lewis's brother the F1 driver) who did a great speech. 64°F.
    I drove until I saw a cheap gas station which was 3.8 miles after the FCD went to 0:

    50.0 / 15.0

    Flashing Empty @ 641 miles :p

    Average FCD over-report over last 3.9 years is 5.25% so I'll adjust the FCD numbers down by that for this tank.


    From gas station to park-and-ride tram stop to take us into the city:

    48.0 / 9.8

    Back home in the afternoon, back a different way to avoid the traffic, 77°F:

    51.5 / 30.7

    We're having a new kitchen fitted so have no cooker at the moment, only a microwave so on Monday the pub was calling!:

    30.8 / 1.4 - short hop to the pub - never good!
    45.0 / 2.2 - to other side of town to collect dog from in-laws
    43.5 / 3.3 - back home

    New tank at 48.3 (FCD 50.9) / 47.4 / Range 615 . Guess gauge F««««|««««E . UG at 45.9 / DTE 573

    I think it is very consistent. I rely on it. Now................why can't Toyota make it consistently ACCURATE ?

    Yes it is consistent, more so than the SG. The Scangauge I have calibrated to within +- 1% and it is reasonably consistent. With my mechanically simple setup I have no such problem like the Prius has.

    53.4 / 5.3 home last night
    69.3 / 5.2 this morning

    Tank is up to 56.1 / 380 mi and juuuuust above 1/2.

  7. Step daughter followed the driving rules for almost a week. (we had both kids sign a 5 page driving contract) She lost the car for a week. So, I drove the sonata a couple times this week when I didn't need the truck.
    She's back from her dad's tomorrow and has to 'help' change the front brakes before she takes the car anywhere.

    Ugh. Been a minute! I had a bit of a bad spot with a broken finger. Disrupted my income, and I am basically now caught up.

    Last tank in my lil ol Civic was impressive, 47.5. It likes summer, it really loves warm ambient temperatures more than any car I have paid attention to. A good grille block will be a must for winter. It likes to stay near 200* and really dislikes alternator loads.

    My truck has faltered a bit, due to the fact that I have gotten a lot of heavy (40,000lb+) loads lately. Nevertheless, the FCD reports not far shy of 9mpg, which is a real testament to how these modern trucks are working to reduce fuel burn. I’d have been about a full mpg less in my 10-speed manual, although company-programmed PCM restrictions actually would have held me back from what this powertrain does deliberately (neutral glides, etc).
