This will cause the oil to get whipped up into what will almost look like a milkshake , and cause all kinds of problems , like oil to come out the breather . If you run a deeper pan it there to get the oil away from the rotating parts .

I run mine where I can just see the fluid on the tip of the stick. I also have a finned pan that helps radiate some of the heat away. On a hot day you can put a fan to blow air under the car and across the fins to help a bit with cooling.
