Question 1

How do I calculate fuel cost per mile?

Accepted Answer

Cost per mile = Gas price ÷ MPG. At $3.50/gallon and 30 MPG: $3.50 ÷ 30 = $0.117 per mile. For EVs: Electricity rate × kWh/mile.

Question 2

What is the average cost per mile for different vehicles?

Accepted Answer

Gas car (30 MPG at $3.50): $0.12/mi. EV (3 mi/kWh at $0.12): $0.04/mi. Hybrid: $0.08/mi. Diesel truck: $0.20/mi.

Question 3

Why does the US use MPG while others use L/100km?

Accepted Answer

MPG (higher = better) is intuitive for comparing. L/100km (lower = better) better shows fuel savings - halving consumption halves L/100km but doesn't double MPG.

Question 4

How does speed affect fuel economy?

Accepted Answer

Most vehicles are most efficient at 45-65 mph. Above 65 mph, every 5 mph increase is like paying an extra $0.20-0.30 per gallon.
