The number before the 'W' indicates the oil's viscosity at lower temperatures. 0W-xx is thinner than 5W-xx is thinner than 10W-xx is thinner than 15W-xx when they are cold. However, at operating temperature (test method defines 212* F) they are all xW-30... they are all the same once the engine warms.
The *BEST* thing you can do is run the lowest number before the W you can find/afford and the number specified in the manual after the W. The 'oil viscosity range chart' is a minimum acceptable temperature range you should run the oil in. As in, if you have engine problems after running 10W30 at -40 degrees, Chrysler will deny warranty claims. It should not be interpreted that you need to switch to 10W30 from 5W30 once summer hits.
Barring synthetics to achieve a 0W-xx rating, all the grades are the same price.

If you want more opinions on "which brand of oil" try searching... topic comes up almost weekly. Stay away from cheap filters like the orange w/ bedliner FRAMs (PH8)

Quick question. My jeep won't start. It runs fine. No issues there. I thought my starter was bad. If i bypass the ignition with a screwdriver the starter spins. Is it not engaging? Is it the silonoid? Is it something else? Any ideas?

Electric related question. Hellas on the bumper use a relay. Switch lights up and really clicks. So just to confirm my beliefs, the positive wire or ground to the lights is acting up. Correct?
