Take the pull-top cap off of a quality water bottle (the type that you can pull up to let water out and then push down to close off the flow) and thread it onto a quart-sized bottle of motor oil. This has several advantages. First, it allows you more control over your oil bottle, reducing the chances of spilling and, in some cases, taking the place of a funnel. It also allows you to direct the oil into hard-to-reach places. And using a good pull-top seals the oil as well as the original oil cap for spill-proof storage.
