Recommended SAE 5W30
How important is it to use SAE 5W30 oil? It's printed right on the oil filler cap. I understand the correct tranny fluid is critical, but what about the engine oil?
Considering the sludge issues the 3.7/4.7 engines are known for...I'd definitely use a lightweight, high quality oil that meets owner's manual specs.
