I have come across a couple of articles online elsewhere advocating the benefits of using an oil extractor to perform an oil change. The extractors praised the most were the economical ones made by Pela (Pela 6000 @ $49 and Pela PL-650 @ $86).
I drive a '79 240D... How do you guys with a similar car feel about using such a device for routine maintenance work? It definitely would make the oil/fluid change experience less messy... but does it perform satisfactorily, in your opinion? Pros and cons?
