Smiles Per Mile

Boy i wish we could edit our posts! should be SPM! :50:
with that your math is squewed. A Prius only get smiles downhill.

So my formula for SPG is as follows

if mpg > 15 then mpg * 10 = SPG
If mpg > 15 then mpg /10 = SPG

For example SRT-8 7L mpg = ~7

7 *10 = 70

Prias mpg = ~50
50/10 = 5
Prias spg = 5
SRT-8 7L SMP = 70

Got mine down to 9.9 mpg lol Granted, this is sitting for the winter for 3 months now and starting occasionally. I also, never drive long distances, so even at my best it's like 16 mpg. When I drove it on the freeway to work I'd get 20 mpg once in a while.

I also drive it like I stole it.
