Oil and Petroleum use is very efficient.

Oil-filled radiators are generally considered to be efficient for heating a room because they use electricity to heat oil, which then radiates heat evenly throughout the room.
It does not matter where oil comes from it is bad for the environment shale oil is just a Les efficient source of oil.
There is enough oil in the ground to last for about 10 years unless new technology is invented. There is enough oil tied up in oil shale to last for many centuries when an efficient way of extracting it is discovered. There is enough oil tied up in the oil sands of Canada to provide for the needs of the world for a century if a more efficient process of extracting it is found.
Oil heaters are generally less efficient than other types of heating systems, such as natural gas or electric heaters. This is because oil heaters have lower energy efficiency ratings and can be more expensive to operate.

An advantage of an oil free heater is that it is more efficient and it will heat up faster than others.
The 10W 40 oil is thicker and is thought by many to be more efficient.
The best way to ensure that your car is as fuel efficient as it can possibly be would be to change its oil regularly. If you know how to change oil yourself, it is important that you perform this task after every few thousand miles. For the majority of car owners, they will take their vehicle to a good mechanic to get the oil changed. This ensures that your car is fuel efficient and eco-friendly.
Cooking oil can be separated by filtration, but certain oils are much more efficient than others in properly filtrating. The best oil for filtration is cottonseed.
1. It is very efficient 2. It is also inexpensive to burn
