What MPG are you using for the compare??

Re: What MPG are you using for the compare??
a possible 6% drop in MPG rating isn't to worry about but Iam a big Technical person and would like to see a standard put in place for reporting MPG is all.
Since ALL cars have a speedo and all cars have a gas tank and all roads have mileage markers to calibrate your speedo too I can only see one sure way for direct comparisons to other vehicles on the road and thats using mileage and pump #s.
Its your site so you can run it like you want I just noticed some people posting NAVI #s that were consistanly 4-8% higher in MPG than there pump #s
I guess I could only post when I do HWY driving and up my #s from 42.8 to 48+ but I won't
I do thank you for this site it puts Hyrids into perspective and how driving habbits can improve or reduce MPG.

Since I don't have the NAV system in my Escapes, I use the odometer and pump method. Sure, you will get some variations from tank to tank but ultimately you still get total miles driven and total gallons of gas purchased. The former over the latter gives you a darned good figure for lifetime mileage.
I use an Excel Spreadsheat to track my mileage and on both Escapes after 4 or 5 tanks you could see the plot of lifetime mileage approach where it is now and pretty much hold there. The individual tanks vary quite a bit but the lifetime average mileage stays pretty flat.
And anyone who thinks there isn't a competition going on here - I remind my wife all the time that she is killing the mileage in the '05 since she started driving it. See the numbers below, you'll see. She's learning though....

To return to the sailing analogy, I'd say what we have here are several boats heading the same general direction; some of the skippers are just cruising, and some are applying every sail and rig tweak they know to squeeze out another tenth of a knot in boat speed. The database contains people with a mixture of purposes. If I understand Jason's position, the database is more a cruise than a regatta, reflecting a variety of driving conditions and purposes, resulting in a big picture of hybrid performance. Drivers within the database can, if they like, set performance targets by observing what other drivers post, or not. I've been motivated by some of the mpg reports and hypermileage discussions; my mpg has improved because of them. When someone in a comparable boat cruises right past me, I want to know "how are they doing that?" I may decide that the effort is not worth the benefit and keep on cruising, or I may join the regatta and see whether there's any way to match xcel and other hypermilers ( the answer is "no," by the way). I see nothing wrong with encouraging drivers who are posting impressive numbers to conform to the math mpg norms used by the other drivers who have a regatta going inside the big cruise. The emphasis would be on "encourage" given the broader, non-competitive purposes of Greenhybrid.
