Question: how much diesel is left?
Answer: At 1,688,000,000,000 barrels of crude oil, the Earth has 442,095,238,095 gallons of diesel fuel left. Assuming a mileage of 5.5 MPG, diesel fuel trucks have enough fuel left inside the planet to travel 2,431,523,809,524 miles. The estimate is enough to travel from the Earth to the sun and back again over 13,000 times.
