Being a technician for a European car brand I can say these things are fantastic! Why other manufacturers didn’t pick up on these is completely beyond me. So sad when the brand in question changed the dipstick tube size and design so these no longer worked. Completely unnecessary change! Still awesome tools and an awesome review. Everything you said about the clear hoses and tank capacity is all absolutely true. We would leave the air hose connected and all the valves open when ducking out oil as you could use the vacuum gauge to see when it was no longer sucking oil. The gauge would rise up to peak vacuum as it is pulling the oil and then deep down to zero or nearly zero indicating it was done. This only works if you have a large enough air supply to handle the constant draw of many CFM of air consumption.
@@rickb6726 MB changed the diameter of the dipstick tube such that the normal oil sucker fitting no longer fits. To make sure nobody attempted a smaller adapter they also drilled holes all through the dipstick tube in the oil pan. So even if you did make an adapter, you wouldn’t be able to pull a vacuum to suck the oil out. They also made the tube shorter so it doesn’t go all the way to the bottom so even if you overcame everything else, you still wouldn’t get all the oil out. Yes you could stick a straw down the tube but the inner diameter of the new tube is so small that it would take way too long to suck oil out with a straw. Anytime something is too useful it’s taken away.
Why not just run the shop air into a single pneumatic switch block built onto the tank that connects your hoses and does all the valve/pressure work for you?
People have no idea how valuable that check valve is because it gets clogged so the other pieces don't. Just brake clean the hell out of it while pushing the valve down to fix.
I am a big believer in fluid extractors for oil changes. I have a MityVac 7300 that must be attached to a an air compressor. to provide constant suction The ones with a hand pump do not provide constant suction and will not remove all the oil. The MityVac is OK for home use, but is too slow for professional use.
A big OOPS! But hey, there was "no mess" haha. Great lesson in valve education. But I have one question, what was the brand of the quick disconnect that you were using? It looked like it was rubberized on the outside and easy to take on and off. I'm an older gentleman and if it would be a little easier for me to manage, that would be great, thanks!
Always include the mess ups! Provides realistic realism. : )
Excellent demonstration of a vacuum extractor
Thanks
When you turned the valve the wrong way I was dying laughing, good one man! LOL
I wish that I could say that I meant to do that for the comedy, but it was true stupidity. lol. Thanks for sharing.
Thanks for the review. I just bought one today. No more 340.00 oil charges at the Mercedes dealer
Thanks!

Richard Lawrence, what do you mean the changed the dipstick tube size and design and they no longer work?

Richard Lawrence, what year did MB change the tube? I have an 11 E63 and would love to save some $$
great review. I now know what to be careful of. Almost bought cheaper changer but your review changed my mind.
Thanks for the review. Just ordered one.
how big or small of a compressor should or can be used ?
Thanks for showing the full mess it made at the end. I was genuinely sad during the video that you edited it.
You’re welcome 😊 It sure was a mess, but it was funny.
What plastic is the thick hose that absorbs the oil from? Doesn't it soften from the heat of the oil?
U should add a regulator om the evaluation side, that way u can just set the psi & open the valve up completely.

That's great intel. Thanks for sharing.
26:09 oh my - that's the worst spill your shop has seen in a long time I bet !
Does it mean, you have to get an air compressor to enable you use this device ?
Yes, that is correct. you need an air compressor to use this. Thanks for watching.

Do you mean the quick disconnect for the air hose? I believe that one is a Prevost safety coupler.
@@Shoptoolreviews yes, thanks!
Very funny
Connect your air conditioning vacuum pump to the oil recovery tank .
if you know how to do oil changes. they arent messy, even done on the ground.
Lol, ok. Thanks for watching.
That thing sucks
Never thought we'd hear that. lol.
@@Shoptoolreviews good to know that you have great sense of humour
