Oh come on 8.72 gallon total tank and you think we can believe you got 800 miles on that one tank. You would have to be getting around 90 mpg and if you're doing that you're in the wrong business and should start your own car company.


800 / 8.72 = 91.7431193

I read it as the car had a total of 800 miles and the last tank - which was only a fraction of that - showed 38mpg.

i am getting upper 40's (MPG) in my stop and go commutes, i just went over 11,000 miles in my smart. my best trip to date was 61.6MPGs, this was for an inter-state commute, 40 miles, average speed of 42mph.

get a scan gauge2, i've had one in my smart for 6 months, i've improved my mileage by 15% with this device, you can see what your smart is doing, and "outsmart" it.

P.S. i got 61.6mpgs with 87 octane gas

Well, I live in an area where avg. sl is about 30-45, and there are a scarcity of lights and stop signs.

And as I said, on an interstate, the mileage is significantly lower.

BTW, my gauge finally dropped this am w/82.2 on the trip odometer.

Yes the car had a total of 800 miles on it and that last tank I got 38 MPG.
The following tank with wide Tires I getting an estamate of 28.

38 to 28

Think I'd be "rethinking" that one

Well as I said before its prolly not so much the tires them self causing the mileage as now I'm more cofortable with corners and the car. A 30MPH corner at 75 may have somthing to do with the milage ;-)

Actually I used to get my best tanks on my old Honda Insight when I broke down and just went off of my "trip mileage". What I am talking about - some cars have a tripmeter A and Tripmeter B (the Insight even had more than that) so I could break down each commutes mileage while still maintaining a tripmeter for the entire tank. If I tried to maintain the highest average for each trip then the tank would come out phenomenal. With that car my best commute was 110 miles at 105mpg. The tripmeter in that car was dead on accurate.

This same thing can be done with the use of a scangauge - just use the "current" screen. Unfortunately I intentionally keep my scangauge tank average set low, for example if it says I'm getting 39.5mpg, I'm most likely getting 41-42mpg.

Oh, rural New Jersey and 58mpg. I DO BELIEVE THAT! Those rural roads in Jersey are perfect for hypermiling up there! I always get MUCH better mileage when I'm driving around up there than compared to here.

I thought you meant total miles on trip meter for that tank not total mileage on car itself.

NP,

Just an update. When I had the tires mounted on the rims they inflated the tires to only 32. The tires are rated at 45 max psi. So I filled to 40psi. That seemed to help a lot and the thrill of taking corners too fast has warn off so that should help too with the led foot
