The comments are pretty much spot on here.
Here is a snippet from how stuff works:
The
viscosity grade (for example, 5W-30) tells you the oil's thickness, or viscosity. A thin oil has a lower number and flows more easily, while thick oils have a higher number and are more resistant to flow. Water has a very low viscosity -- it is thin and flows easily. Honey has a very high viscosity -- it is thick and gooey.
The net of all this is to stick with your oem requirements, however if you are a tad off with the 5w you will be fine for now but stay with the 0-40 as these cars were designed for the oil specified.
