Crude, Synthetic, or Crude synthetic?
The black, thick, stinky stuff we know as crude oil is made up of many different things. In addition to hydrocarbons and hydrocarbon compounds, there are also varying amounts of sulfur, nitrogen, oxygen, metals such as nickel or vanadium, and water containing salts. Many of these have to be removed by refining in order for the oil to be usable. Once the crude is refined it will fall into a base oil category. The American Petroleum Institute (API) has developed a classification system of five groups based on manufacturing process, saturate & sulfur levels, and viscosity index. Group I is the least refined, while Group V is made up of chemically engineered base stocks.
What is “Synthetic”?
Synthetic oil is available at almost every repair shop, dealership, parts store, and quick oil change place. But how synthetic is it? In 1999 the National Advertising Division (NAD) ruled that some Group III base oils can be classified as synthetic. These petroleum base oils are highly refined, but are still petroleum based. Synthetic base stocks that are chemically engineered include Synthetic Hydrocarbons, Polyalphaolefins (PAO), different variations of Esters, Silicone fluids, and Polyglycols (PAGs).
In today’s post, we can see that all oil is not the same, and all synthetic oil is not the same. Many of todays vehicles require synthetic oil, especially vehicles with turbochargers and superchargers. Can the vehicle owner be confident that the synthetic oil being put in their car is 100 percent, pure synthetic, or is it a petroleum based Group III synthetic?
