If it calls for 5w-20 use only that weight ......We see many of these cars that go to the Quickie lube and get the wrong oil in them. ..........Most of the sludging issues we see on newer engines are due to the use of heavier than specified oils. ...The 2.4 is a variable cam timing engine, and the 5w-20 is critical to proper cam phaser opperation . .......The instructors repeatedly drilled this to us at Chryslers training center........Tom
