SAE classes and their meaning The numbers above the oil application range define its SAE (Society of Automotive Engineers) class. For multi-grade oils, this covers two grades e.g. 0W-40. These specify the operating temperature range for which the oil is best suited. The number before the...
“Our ancestors burned the oil of Earth madly and wilfully. They destroyed its coal recklessly. We despise and condemn, them for that, but at least they had this excuse—they thought that when the need arose, substitutes would be found. And they were right. We have our plankton farms and...
