pancakes

When y'all make pancakes do y'all use butter or vegetable oil? I use aunt jemima however you spell it. All I got to do is add water to the pancake mix. But when cooking it on the pan do y'all put butter so it won't stick or the oil? How much do y'all put? Just asking since I use butter but everytime I make pancakes it burns more on one side. They also look ugly and a little raw when I'm done cooking them.
