Not to promote a specific product - but I think this one is great for super easy oil changes. A MityVac oil sucker thingey . . . http://www.amazon.com/gp/product/B0002SR7TC/ref=oh_details_o05_s00_i00?ie=UTF8&psc=1 - I got the large size one here as my little Alfa Spider takes 7 quarts of oil in a little 2 Liter motor - and the Mercedes takes about 8. It sucks the oil out the dipstick, and about every 8 months I plan on removing the drain plug. Mine's kind of worn, so the less I remove it the better. The filter is still a mess to remove but this stores the oil oil and you just take the unit to the locak auto parts store and dump it out.
