it was very cheap and very easy to get
it has suggested that gulls petrol is not as fuel efficient as others and also your mum
its less fuel efficient because it burns quicker then diesel.
Petrol is more efficient as a fuel than ethanol, because the energy generated by burning a fuel is primarily released by formation of bonds between oxygen and carbon or hydrogen. One such bond already exists in an ethanol molecule, whereas in petrol few or no such bonds exist.
The only demand that will become high when petrol prices rise is the demand for fuel-efficient cars.
The most fuel efficient SUVs so far released in 2013 are those by Honda. These are proving very popular, have had good reviews and selling well. The fuel efficiency is better for the diesel rather than the petrol models.
Both would be good on fuel economy but Honda has a better overall reputation.
diesel only comes in fuel injection, the fuel needs high pressure to ignite, and cannot only be sucked in like with a carburator on a petrol engine
Diesel engines are more efficient and do use less fuel, but they do not cost less than a petrol engine, they cost more. Diesel fuel also costs more. A diesel engine will however last longer.
Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.
petrol is a hydrocarbon fuel
diesel is more efficient
No Petrol is a fossil fuel
