A typical modern application would be Honda motor's use of 5W-20 (and in their newest vehicles, 0W-20) viscosity oil for 12,000 kilometres (7,500 mi). Engine designs are evolving to allow the use of even lower-viscosity oils without the risk of excessive metal-to-metal abrasion, principally in the cam and valve mechanism areas.
It was introduced in 1974 as a Multi-grade 5W20 viscosity synthetic motor oil. The brand now includes multi-grade motor oils, oil filters, synthetic grease, transmission fluids, and gear lubricants. [14] The Esso and Exxon motor oil brands have largely been discontinued.
We should probably fix this section up. I noticed that the Mercury Grand Marquis 2002+ was listed as taking synthetic, noting that it takes 5W20. It uses the Ford modular 4.6L V8, so if that engine needed synthetic, MOST police cars in the US would be forced to run synthetic, which is not the case; ask any fleet manager.
A sample of synthetic motor oil Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks .

The oil fails the test at a particular temperature if the oil is too viscous. The grade of the oil is that associated with the coldest temperature at which the oil passes the test. For example, if an oil passes at the specified temperatures for 10W and 5W, but fails at the 0W temperature, the oil is grade 5W. It cannot be labeled 0W or 10W.
