How many miles per gallon does a Double Decker bus get UK?
IIRC, normal double deckers tend to be 4-6MPG, with hybrids getting 8-10MPG.

Most of those buses get between 6 and 9 miles per gallon. Thats about the standard for 5.9 to 8.2 Liter diesel engines. Mileage for busses is impacted by the start and stop nature of their use. Mileage for similar engines in over-the-road buses and motor homes will average a few miles per gallon more.
Diesel school buses are already the most fuel-efficient in the industry, due to a higher BTU count compared to other fuels, providing better fuel economy and a longer operating range compared to similar-sized gasoline, propane or compressed natural gas (CNG) engines.
Fuel efficiencyFuel efficiencies used in this analysis were as follows: diesel bus: 4.82 miles per diesel gallon; diesel-hybrid bus: 5.84 miles per diesel gallon; natural gas bus: 4.47 miles per diesel gallon equivalent; and battery electric bus: 2.02 kWh per mile, which accounts for a 90 percent charging efficiency.
A typical passenger car carrying one person gets 25 passenger miles per gallon, while a conventional bus at its capacity of 70 (seated and standing) gets 163 passenger miles per gallon. These fuel savings yield commensurate cuts in CO2 emissions.
On average, a standard double-decker bus in the UK can seat between 60 to 90 passengers, with seating arrangements that typically include both upper and lower decks. However, some double-decker buses in the UK can have even more seating capacity, with some larger models accommodating up to 120 passengers or more.
“A typical passenger car carrying one person gets 25 passenger miles per gallon, while a conventional bus at its capacity of 70 (seated and standing) gets 163 passenger miles per gallon.” So the claim : A full bus (70 people) is 6.5 times more fuel efficient then a car.
A diesel engine requires less fuel to produce the same output as a gas engine. A conventional gas engine operates via a spark ignition system, which burns more fuel than a diesel engine's combustion system. As a result, diesel buses are more fuel-efficient per gallon and burn less fuel while idling.
