Hi all -
Some time ago I picked up a case of Chevron 10W-30 before I knew much about oil. Since then, I have come to find out both of my vehicles suggest 5W-30 in the owner's manual. I have been using 5W-30 (Chevron, Shell and QS) but still have that unopened case of 10W-30. Are there any compelling reasons to not use the 10W-30? Temps here are very mild, so my thinking is it shouldn't matter. Thanks!!
