Best fill in 6 years in the Firefly/Metro: 84 mpg US with 3 new mods

I've seen some very encouraging numbers on the ScanGauge after my latest batch of mods (done since my last fill-up), so I filled the Fleabag before hitting the half-tank mark because I wanted to find out if they were for real. (And I made sure I filled it right to the top of the filler neck.)

2.8 L/100 km = 84 mpg (US) = 101 mpg (Imp)

That's over 582 km / 362 miles of my typical summer usage: mostly on scenic route & back roads, with a max posted speed limit of 80 km/h / 50 mph.

The latest mods...

1) New air dam:

2) LRR RE92's:



It's now wearing the worn out set of RE92's on alloy wheels from the ForkenSwift (RIP).

3) Full wheel discs




I re-used the discs from my failed magnetic attachment experiment (zip ties this time!). A little bit sad to cover up the pretty Suzuki alloys, but the results are attractive in their own way!

Ever since I put the air dam on, I could have sworn that my butt-o-meter was telling me good things. And then with the wheel/tire change, it got even better.

It's actually one of my best non-pulse & glide, non-competition tanks. Not counting those, I beat it back in 2008 when I was alternator-less for a portion of that fill. But I haven't run without the alternator for a few years now.

And comparing some trip data, I had a best ever trip to & from my friends' cottage, AND with the highest average speed I've recorded on that trip. (I tend to spend some of my efficiency dividends on going a bit faster.)
