2008 Ford Edge: What is the oil type and capacity?

EacH2008 Ford Edge comes with the same 3.5L V6 engine, which makes deterMINIng engine oil type and capacity relatively simple. Your Edge will require 5.5 quarts of SAE 5W-20 synthetic motor oil. In emergency situations where 5W-20 is not available, it's permissible to also use SAE 5W-30 in the short term -- though it's extended period use is not recommended. To understand why, we must look at what the numbers in an oil's weight mean. The first is the viscosity at startup temperature, and the second is at operating temperature. Higher numbers mean a more viscous (thick) oil, which can introduce friction into engine operation. Over the long term, this can prematurely wear and tear Your engine, which can likely lead it to fail sooner. Therefore, it's worth paying the few extra dollars for the "better" oil, so long as Your engine can use it.
