In the summer when I don't use the a.c. I get about 50-55 mpg, so far best is 62 mpg. With a.c. I'll get about 43-46. This is because of driving style, Higher than normal air pressure in the tires (max sidewall), 185/65-15 tires on the rear and 185-60/15 tires on the front(the biggest I could get on the car), aerodynimic improvements, modified exhaust and fairly open roads with rolling hills. I recently had an exhaust leak and I temporarily replaced the exhaust with the factory exhaust and the mileage went down. It's quieter now but the aftermarket exhaust is going back on when I have the time. Keeping the speed down makes a big difference, above 50 mpg I usually lose 1 mpg for every mile per hour faster average. Chumly

I've had 3 Smarts, the 1st '08 was all stock, easily maintained 40-42 mpg, the 2nd Smart, another '08, I did not have it long enough to record a solid mpg record because of personal reasons, my present '09 Brabus has 17" wheels all the way around, nothing modded to the engine(not yet anyway) and I average 39+ mpg, it doesn't matter how easy I drive this one, I cannot get to 40, but I have a small notion it's because of the Brabus chrome gas pedal, it goes to the floor way to easy(lol)

Your fuel gauge observation occurred because the fuel gauges in these cars aren't linear. Each bar is not representative of a gallon but more of a calculated approximation. The first bar lasts 70-110 miles in my car. In that distance, it's already burned off two gallons of petrol. Every bar after that falls off in 30-40 mile increments. The "1 gallon countdown" in my car also adds an additional 30 miles on top of the miles the final bar gives me.

Sadly the fuel gauge shouldn't be used to calculate MPG as it has its own crazy programming that isn't linear with actual fuel level.

When I was homeless then subsequently unemployed, I used 87 octane exclusively in my 2012 451. At the time, Premium was basically a dollar more and every dollar counted. I ran it for over 20,000 miles like that with no adverse impact. The car routinely returned 45 mpg without struggle.

I started using 93 again after the (unrelated) fire...kinda used it as a sign to take better care of the car.

Nowadays, the car still returns 45 mpg on 93 octane at 133,000 miles and about 33-35 mpg while towing a 1,000 lb trailer.

My 2016 453 gets 45-55 mpg so long as I lay off the turbo.

it takes time grasshopper

5 days will normally not produce a few tankfuls of MPG numbers. The gas tank was most likely not full when you purchased the car, no matter what the previous owner/salesperson may have told you. Also, different gas pumps cut off at different levels in your gas tank, and while a half a gallon does not matter when you have a 20 gallon tank, with an 8 gallon tank it is more significant.

Let us know what your mileage is after 3-4 tank fulls.

If I had to guess, I'd say my MPG is about 35-40 on my Peanut car. My Subaru Forester gets 33, but is not the same and is not sporty like my Brabus. And the Brabus scoots along in some situations which make it a blast to drive.
I have a ScanGauge/e but use it to watch engine temp and voltage.
