oil change - do it yourself

You should find the oil drain plug on your 2000 BMW 740i on the bottom of the engine oil pan. There may need to remove the under side air deflector to gain access. The oil filter is most likely a cartage type located on the top side of the engine. When you consider the cost of purchasing the oil and filter, the time involved in changing the oil, and the issue of what to do with the used motor oil, you may decide it is better in the long run to have your oil changed by your local mechanic.
