What is thicker fuel oil or petrol?

Fuel oil is thicker than petrol because it has a higher viscosity and density. Fuel oil is used in heating systems and diesel engines, while petrol is used as a fuel for gasoline engines in cars.


Viscosity of gasoline?

The viscosity of diesel fuel is directly dependent upon the temperature at which it's kept. At 100 degrees, the viscosity may be as much as 140 SSU. The higher the temperature, the lower SSU, so at 130 degrees the viscosity may only be 70 SSU.


Will a lower temp rated thermostat have any effect on fuel economy?

No, it could actually decrease fuel economy by decreasing the oil viscosity.

Vicosity increases as temperature increases?

"Viscosity" is basically a resistance to flow. Viscosity is inversly proportional to Temperature. For example, high viscous heavy fuel is heated to right temperature to lower its viscosity for proper combustion in diesel engines or boiler.


What fossil fuel is used to make petrol?

petrol is made from the fossil fuel oil


Why petrol cannot be used in diesel engine?

Two main differences: The fuel intake system is different and the firing mechanism is different. First, Petrol engines fire using spark plugs instead of heat and compression, and they might not get the diesel fuel to ignite fully if the compression is too low. Second, Diesel fuel has different viscosity, different volatility, different cleanliness standards, and different air/fuel ratios, so the fuel injection system has to have different design features.


Can we use fuel injector in petrol engine?

Yes, you can use a fuel injector in a petrol engine.


Why is petrol more efficient than ethanol?

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.


What is petrol fuel?

Petrol is the term used for gasoline in some countries, like UK, Australia, New Zealand
