OK . . .What does a 5W-30 do that an SAE 30 won't? When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. The numbers without the W are all tested at 210Â° F or 100Â° C which is considered an approximation of engine operating temperature.
(Answer #1). The Industrial Revolution was a time when the world's economy started to be more industrialized -- things came to be made in factories rather than by individual artisans. Great Britain took the lead in this largely because of geography.y about mid nineteenth century it took firm roots in western Europe and northeastern USA.

The two most important of these are abundant supply of coal and iron and the economic advantages accruing to the country because of its colony.
The Industrial Revolution began in the United Kingdom and most of the important technological innovations were British. Mechanized textile production spread to continental Europe in the early 19th century, with important centers in France.his second Industrial Revolution gradually grew to include chemicals, mainly the chemical industries, petroleum (refining and distribution), and, in the 20th century, the automotive industries, and was marked by a transition of technological leadership from Britain to the United States and Germany.
