Recent gas expenses, and how much I make per mile:
January: $201 ($1.83)
February: $235 ($2.10)
March: $260 ($1.87)
April: $242 ($1.80)
May (4/29-today): $34 ($1.79)
Note how well I did in February...gas prices at the time were around $2-2.20.
I think I've done everything I can to maximize my profit and minimize costs, except for running stop signs.
