Which Oil Evacuator to buy?
 

We had used up our last "included service" on our CPO 2014 E350 so it's finally time: I gotta do an oil change.
So I read up on it and it seems oil evacuation from the dipstick is actually the preferred method ...go figure! OK guys, so without breaking the bank and getting esoteric, which Evac tool is the one that simply works as it should? Name names, gents ...not to mention how much ya got it for! :) Thanks a bunch!!!

I personally have this model, SHURflo 8050305426. Connects to your car battery (cord is a few feet - lots of length), flip the switch, and let it run. Has great capacity, built in safety features and overall works like a charm. Includes extra long tubing that easily reaches bottom of our dipstick tube. Change the oil in about 20-25 minutes mess free. Costs about $130-150 online. Never have had such easy oil changes before this pump and the top engine accessible oil filters on Mercedes. I prefer this over the eVac style where you have to pump.

For those retirement age people (like me) who realize that hand-pumping a topsider is infinitely easier and less taxing than crawling under the car, a Mityvac 7400 is a good choice. I've used the more expensive evacuator/dispensor model for 12 years now, but have never needed to use the dispensor feature. So I would get just the evacuator model. 7.4 liter capacity is just the right size for the high capacity sumps in our cars... $55 to $70 depending on where you shop...

I've used that Mityvac since I got the car and its been great. I do occasionally go the old fashioned route and get up underneath to drain but only to have a look at things with the plastic pan removed.

I was thinking about the mityvac, but that ShurFlo looks pretty cool, and not that much more dough than the MityVac. The thing that concerns me about the hand-pump versions is the reviews I've read talk of occasional problems with the vacuum seal deteriorating, especially over multiple uses, and so it takes more and more pumps to keep it working until it finally ends up dying and you have a large useless cylinder.

My "thought" is that with an electric motor, it is less likely to break, and doesn't rely on any vacuum seals ...so long as the motor works, that's all that's needed to evac the oil to drop into a bucket. Hey elohite, how long have you had yours for, may I ask? And does it come with the right hose end to fit into the MB dipstick? The amazon listing makes no mention of what fittings it comes with. Thanks!! :)

I have had it for about 2 years now and around 15+ oil changes on various family cars without any issues. I foresee many years of use to come and if it did somehow break by chance I feel it has definitely "paid for itself" and I would repurchase it again in a heartbeat. The tubing diameter on this is perfect sized and overall long length is perfect for the MB dip stick. Trust me, you won't regret getting this over the hand pump versions. :y

Something to consider is the ease with which the evacuated oil can be transferred from pump reservoir to a disposable plastic container The Mityvac has a wide pouring spout that makes fluid transfer to old milk jugs easy. From the pictures, I can't see if the Shurflo has a similar pouring spout.

Perfect, Elohite ...that's just what I wanted to know. Thanks!! :)

FWIW, I like the fact that the Sureflo (and its competitor the Jabco) are in a bucket with which I can just go to my local auto prts place and dump the oil there. No need to transfer to any other container ...easy IMHO! Thanks, all!!!

Just a quick add-on…if you're using a vacuum engine oil evacuator, there's no need to use a long, thin hose in an attempt to reach the bottom of the oil pan. The stock dipstick tube goes all the way down and is a convenient "straw" to vacuum the oil out. Just make sure there's a tight air seal between the dipstick tube opening and your vacuum device. I was having difficulty getting more than 5 liters of oil out using the thin tube that came with my Mityvac. Then I remembered reading about this tip so I reconfigure the Mityvac to seal against the dipstick tube instead, and I got 8+ liters out, which is expected for the M278 engine.
