What it costs to keep fuelled
$4,444a year, fuel only
The 1991 Dodge AW100/AW150 Ramcharger 4WD is EPA-rated at 10.8 MPG combined (9.8 city / 12.3 highway). Over 15,000 miles a year that is about 1389 gallons, $4444 a year in fuel, or $0.296 per mile at $3.20/gal.
Across its full 1984–1991 run it averages 10.8 MPG, essentially flat across 8 model years.
The band is how far one gallon carries it: 10.8 of the 60 MPG this scale runs to. The square tick is the special purpose vehicles average, 17.7.

How this is worked out
- Start from the EPA combined figure for the model year — a laboratory test cycle run to a fixed procedure, not a road result. Where a year sold several engines or drivetrains, the trims are averaged and the trim count is printed beside the row so you can see how much averaging is behind it.
- Fix a pump price. This site keeps one reference price, $3.20 a US gallon, fixed JUL 2026 and printed next to every dollar figure it produces. It is an assumption with a date on it, not a quote — put your own price in.
- Fix an annual distance. Every annual figure on this site uses 15,000 miles a year, roughly the US average. A cost per year with no stated distance is not a number, it is a mood.
- Divide distance by economy for gallons, multiply by price for the year's fuel, divide price by economy for one mile. The per-kilometre line is that last figure divided by 1.609344 — the same money, in the unit most of the world drives in.
- Stop there. No depreciation, no tyres, no insurance, no servicing. This is the fuel line of the ledger and it is labelled as one; depreciation usually dwarfs everything on it.
gallons/yr = miles/yr ÷ MPG fuel $/yr = gallons/yr × $/gal cost $/mi = $/gal ÷ MPG cost $/km = cost $/mi ÷ 1.609344

Re-run the ledger at another pump price
Every line above rests on one pump price. Here is the same entry re-costed at six others, because the price is the part that changes while the test sheet stays put.
