Gary<gary_mayfield@hotmail.com> asked:
I've always wanted to ask..... What is synthetic oil made from?
True synthetic oil is manufactured from polymeric precursors in processes
similar to other polymers and plastics. Thanks to big corporate $$ lawyers,
synthetic as applied to oil no longer means this. A good paper describing the
differences between oils is found at:
http://zddplus.labecon.com/TechBrief10%20-%20Oil%20Base%20Stocks.pdf
The big advantage of synthetic base stocks is their relative lack of parametric
delta. A 30W mineral oil has a much broader spread of actual molecular weights
than does a synthetic 30W oil. Synthetics in general are more stable over
their environmental range.
