The fuel math, in five sentences
Assume a 400-mile tank, reserve about 15 percent of it, and the usable round trip is roughly 340 miles — our 200-mile one-way cap stays inside that. At 25 mpg, the longest trip in this table (394.7 mi round trip) uses 15.8 gallons, or $55.26 at $3.50 per gallon. Distances are straight-line times a road factor, so your odometer will read a little different. Tank sizes vary from roughly 300 to 500 miles across the fleet. Check current pump prices when you plan — $3.50 is a national-average assumption, not a quote.
