How To: Change Your Oil, Part 2
How to actually change the oil
Keep in mind that this is only a guideline for the actual procedure. This is where you should check a service manual to be sure you’re not screwing anything up. (Honestly, my Land Rover is the only vehicle I’ve had that is very specific about the operations procedure, but you never know) Failure to follow the factory instructions can result in the oil pump losing its prime and, thus, its capacity to pump oil. Remember: oil serves as a much better lubricant than air does. The same principle applies if you forget to purchase all your oil and filter prior to getting started. It is tough to drive to the store with no oil in the engine*so be sure you have ENOUGH OIL and the PROPER FILTER and the PROPER TOOLS before you proceed. Got it? Good!

Draining cold oil isn’t recommended, as you will be leaving all kinds of dirt inside the engine. By driving your car a few miles before draining the oil, you’re stirring up all the sediment into suspension so it will flow out of the sump with the old oil. Plus, as an added benefit, hot oil running down your arm will warm your extremities if you are forced to service your car in sub-freezing temps. Read more
