Ton Miles Per Gallon

as that’s a valid concept.

Shuffling an individual around bereft of gear or goods lacks meaning. Just “means” he does it with the air conditioning a motorcycle lacks. But he can’t account for unused capacity re empty seats and cargo space. IOW, it’s no test.

Make the test[s] real.

Vehicle scaled weight against published shipping weight (curb weight) for any test.

Loaded to limit, is the real FE test.

66-75% capacity for regular driving as the baseline.

.

Do I get to use my 18-wheeler for that? Because ton-mpg makes this thing look like a star, and I drive waaaaaaaaaaaaaaay more miles in this than in any car...

Is this at 50-40 mph pulse and eoc?

I'm after it! Just recorded a 62 mpg tank that averaged about 72 in the last 200 miles because I started hypermiling the car more aggressively. Probably would have been a 58 or 59 mpg tank. Just refilled, now I have my wheel well covers back, and this is gonna be my 70 mpg tank!

Leg 1 was some low speed between lights and then 55-40 EOC

Leg 2 was 40-30 EOC

Leg 3 was 55-40 EOC and then some in town at the end...

Thanks for posting back.
How do you keep battery voltage up?
Mine drops to 12.3v if i eoc too much with the headlights on

[mpg_numbers_guy]

^ when I do EOC I bump start the car 90% of the time to avoid further 12V drain from engaging the starter. LED headlights cut headlight draw in half. I still see 12.3v every now and then, and sometimes 12.2v, but most of the time it never goes below 12.5v.

A deep cycle battery, either AGM, lithium or maybe a supercap setup, is in the works when my almost new 12V goes bad down the road.

[19bonestock88]

^ same. My FLA battery is fairly new and hasn’t had even the slightest issue starting the car, and I don’t consistently hypermile enough to cause a consistent battery drain... admittedly since I left my day job and am getting divorced again I’ve not always felt up to it lol

Hi,LEDs are technically illegal in the uk
..
I was thinking adding a solar panel, to charge the battery just after I park the car, but they don't work during the night

Nope, but it's more fun if it is between now and the end of summer in late September. I'll be doing it a second time (first was in 2014).

You're still really close at 67 or 68 mpg. Go for legend!
