An oil change for a 2008 VW Rabbit can be accomplished at home to save money and time. Drive the car upon ramps, locate the oil tank, place the oil pan underneath the spigot and unscrew the cap to drain. Locate the oil filter and using the appropriate wrench, remove. Take the new filter, place a bit of oil on the O-ring and screw new filter in. Add new oil and drive away.
