400 miles to the gallon
To estimate the cost of driving 2,000 miles in diesel, you'll need to know your vehicle's fuel efficiency (miles per gallon) and the current price of diesel per gallon. For example, if your vehicle gets 25 miles per gallon and diesel costs $4 per gallon, it would take 80 gallons of diesel to cover 2,000 miles (2,000 miles ÷ 25 mpg). Multiplying the gallons by the price per gallon, the cost would be approximately $320 (80 gallons × $4). Adjust the figures based on your vehicle's efficiency and local diesel prices for a more accurate estimate.
