| Petroleum products, such as gasoline,
kerosene, home heating oil, residual fuel oil, and lubricating oils, come from
one source - crude oil found below the earth’s surface, as well as under large
bodies of water, from a few hundred feet below the surface to as deep as 25,000
feet into the earth’s interior. Sometimes crude oil is secured by drilling a
hole through the earth, but more dry holes are drilled than those producing oil.
Pressure at the source or pumping forces crude oil to the surface. Crude oil
wells flow at varying rates, from ten to thousands of barrels per hour.

Call American Their Names A great difference between American social customs and those of other countries is the way in which names are used. Americans have little concern for "rank", especially socially. Most Americans do not want to be treated in any especially respectful way because of their age or social rank ; it makes them feel uncomfortable. Many Americans even find the terms "Mr. ", "Mrs. " or "Miss" too formal. People of all ages may prefer to be called by their first names. "Don’t call me Mrs. Smith. Just call me Sally. " Using only first names usually indicates friendliness and acceptance. However, if you do not feel comfortable using only first names, it is quite acceptable to be more formal. Just smile and say that after a while you will use first names but you are accustomed to being more when you first meet someone. Very often, introductions are made using both first and last names: "Mary Smith, this is John Jones.
