I believe it to be purely economics. The drain plug may add 10 cents to the cost of the pan. Take that times the number of pans purchased and you will understand. Also the manufacturer doesn't want you to do any maintenance so you will be back to buy another car as soon as possible. Of course the dealers and service companies want you to come to them for maintenance and the time it takes is factored into the cost. Just my opinion. MN.
