The service manager at the VW dealership recommended an oil extractor for our diesel Jetta. Since the oil filter is on top in the engine compartment, I don't have to drive it on ramps, get under the car, remove the sound pan, etc. Makes for a much cleaner and easier job of changing oil. I've used it on other vehicles too, but still have to get underneath for the filter. Handy for changing oil in lawn equipment and removing oil or fluids from anything that doesn't have a drain. Overfill an engine with oil? Not a problem, the oil extractor will take out just the right amount. It is all plastic, but seems very durable. The Amazon price was right - $12 to $15 less than I found at other vendors.
