Not a lot to say except that it does what it’s supposed to and it does it very well. For years I used a 5 gallon bucket with a 12 V vacuum motor attached to the top lid. It was such a mess to deal with the oil afterwards. The whole unit was just an oily mess. I gave this a try because I’ve heard so many positive things about the self-contained purpose specific oil extractor like this. Super easy to use and super clean and easy to pour the oil into another container for disposal. Changed the oil on my twin 300 Yamaha. It removed exactly 6.4 quarts as I expected and hoped. Not a single drop of oil ever hit the ground. I have found my oil change buddy.
