Bests & Worsts Reviews from Amazon

I own a few cars (4 at this given moment, just between my wife and I) and, while I don't mind oil changes, I don't particularly look forward to climbing under the car, getting burned by oil, etc. I actually stumbled upon the Topsider after looking at numerous other options, none of which had enough capacity to handle the 9.5qts from my 2004 Audi S4. I first tried it on my 2005 Lincoln Navigator but the hose was too large to fit all the way down the dipstick tube so it wouldn't work. This wasn't a huge issue for me because I had to get under the car, anyway, to change the oil filter. Today, I used it to change the oil on my wife's 2004 Mini Cooper S. I followed the instructions - clamped the hose, pumped it 40 times, stuck it down the dipstick tube, released the clamp and waited to hear bubbling. It was honestly that simple. What's funny is the Mini was only supposed to take 4.7qts of oil (5 was OK) but the previous owner must have overfilled it and the topsider removed about 6 qts - all very effortlessly. I can't wait to use it on her 2001 BMW 330i or on my S4 - should make the jobs much easier. Even though it didn't fit the 2005 Navigator I still gave it 5 stars because it will make life so much easier, overall. I've already recommended it to several friends and one friend is borrowing it to do his 2003 E320 tomorrow. Very excellent product. ===== UPDATE 3/11/2015 I've been using the Topsider for about a year now during which time I estimate I've performed between 10 and 15 oil changes, plus a few buddies borrowed it for a few oil changes. I am still as thrilled with this product as the day I purchased it. Like other users, the little plastic clip began to weaken and wasn't holding like it previously had, so I decided to build a shut-off valve myself and I couldn't be happier. I went to Home Depot and picked up a ball shut-off valve, a few couplers and some hose. Now there is zero loss of suction and no more clamping of hoses. I recommend this to all my friends and family, it's a terrific product, well made and immensely helpful.
