Geez - give it a rest!

I assume you are looking at synthetics, and Hyundai recommends a 5W-30 for that engine. Don't use Castrol Edge 0W-30 European Formula, although Mobil 1 0W-30 AFE is OK because it is not a European Formula oil.

Personally I think Royal Purple is overpriced and about the same as a mid-quality synthetic. Probably the best of the three brands mentioned is Mobil 1 EP (Extended Protection) 5W-30, and Walmart sells it in 5 quart jugs at a very reasonable price.

That was me. I use a Mityvac 7300 Fluid Extractor that is hooked to a small air compressor that I already had. Since the 2009-2011 Genesis V6 has the oil filter on top, using a fluid extractor to pull oil from the dipstick tube completely removes the need to jack up the car for oil changes. My understanding is that most BMW and MB dealers use fluid extractors also. It doesn't always work with all engines, but does work fine with my Genesis V6, and I get more oil out that way then via a drain plug ("if" I spend a few minutes and move around the plastic tube that goes into the dipstick to make sure it gets the maximum amount out).

Someone with a 2015 V6 said that the oil filter may be accessible from the top by someone with long arms, even though the filter is mounted at the bottom. But I have no confirmation on that. I don't believe there is any way to do that on the Genesis V8.

One reason I use an oil extractor instead of ramps is that it seems like it would be hard to get all the oil out via the drain plug if the car is not level, but I don't have much experience with ramps to verify that.

I hope I will not be punished for posting in the 2015 section of the forum even though I don't own one.

I am quite familiar with oil extractors and yes they work well however unless the car is designed to have the oil removed this way then chances are you will be leaving quite a bit in the engine compared to the old fashion plug which was designed for removal of the most oil.

Boats are well known to use oil extractors as most you have no access underneath. The engines used in these are of the American iron type and you will leave almost a quart in those if you extract. Been there done that. On the other hand I also own a PWC and there is no other way but to extract however the design of this is made to use this system and allows for almost complete oil changes. Notice I said almost.

Bottom line is if there is a drain plug, you will remove more than an extractor ever will.

But as Mark pointed out, is that really true if the car is up on ramps and not level?

Gravity always works.

Depending on design it may hinder or actually help. I have no clue if this works well on the Gen 1 or 2 for that matter. If Hyundai says to use the drain plug then this is what I would do. Mercedes on the other hand uses extractors on many of there cars but they are designed for this. Even so I still use the drain plug on my Mercedes. Something about the fact that any contaminants will accumulate on the bottom and draining via the plug will flush them out for sure.

True - but not necessarily to your advantage if the drain plug ends up higher than the low point of the oil pan when the car is on ramps??

 

[Mac West]

Works just fine.

I agree that an oil extractor may not work on all engines. But it does work well on my Hyundai 3.8. I have measured the amount of removed during oil changes to see how much oil is removed via an extractor vs drain, and I can get more oil removed from the extractor. Aside from measuring the amount of oil removed, I can tell that the extractor does a better job than a drain plug because my new oil is much cleaner after the first drive, since there is very little oil in the crankcase after using the extractor. However, I do move the plastic tube (that goes into the dipstick hole) around a few times to make sure I the end of the tube is at the bottom of the pan. I also had good luck with a V6 Toyota engine. So my experience is at odds with yours, since I get more out via the Mityvac extractor with an attached air compressor.

When I first tried an oil extractor, I used a hand pump version to create the vacuum to start the extraction. That did not work well at all, and I now use a Mityvac extractor that requires that an external air compressor be attached (a small one is fine). Using an air compressor can pull out physical containments out the bottom of the pan, as a fair amount of suction is generated by the attached compressor. But the oil filter will catch the containments anyway.

Not saying your results are incorrect however as mentioned all depends on design of the engine, mostly of the pan and dipstick location. Dipsticks are dipsticks and are not intentionally designed to be positioned in a location to extract the most oil. In your case it works fine however from what I have read so far the 2015 has a redesigned oil pan because it now holds something like 7.25 quarts so we cannot assume it will work well on the Gen 2 until someone experiments.

My Mercruiser engines which are basically from a 350 GM small block would always have dirty oil after an oil change through the dipstick and this always bothered me. I needed to pull both engine several years back and took the opportunity to install a remote oil change kit as I now had access. Basically a hose connected to the oil pan drain plug and then connected to a pump which amounts is the same as draining from the plug. Oil is now golden after a change and I get an additional 3/4 quart out of each engine. Obviously the extraction method worked poorly on this design although it is the recommended method by Mercruiser due to constraints in the boat.

325 prop HP each. On a good day I get 1.25 mpg.

That's all? Mine is shrinkwrapped for the winter or I'd show you my 7.4 liter (454 big block) Mercruiser (though only 1)
BTW - Super clean bilge: you're as meticulous as I am, it appears - very nice!

32' express cruiser used as a weekend cottage. Have highly modified the entire boat over the last 10 years. 1997 but looks like new and works like new. Always vacation on the boat every year. My only way of pulling the plug and relaxing. Boat picture album for those interested. Now you know why I call myself Midnight Sun. http://midnightsun.smugmug.com/Midnight-Sun-Photos/

Now back on subject.

I said up front that "It [oil extractor] doesn't always work with all engines." I don't know why you think I claimed otherwise.

But one thing I noticed when I first starting using the extractor on my Genesis V6 is that the first time I used it the tube got stuck far from the bottom, and I left almost 2 quarts in the crankcase. But next time I experimented with turning/twisting the tube to make sure it was at the bottom, and then after all the oil seems to be extracted, then moving it around even some more, and only then did I get it all out (and a lot more out using the extractor than with the drain plug).

Also, if you use one of those hand-pump extractors on your boat, those are worthless. I know because I tried one of those before I bought the MityVac version that uses an external air compressor.

I have a pella unit. They work very well. Really no need for an air compressor as once pumped up it will empty the entire engine with the suction that was created. About 20 strokes is all it takes then sit back and let her suck. http://www.pelaproducts.com Here is a video on how to use it. As you can see he pumps it up at the beginning and then lets it do the work. Pretty simple, clean and fool proof. https://www.youtube.com/watch?v=wawzok1uzdE

First extractor I bought was a Pella that I bought at a boating place. Absolute POS. No wonder you think extractors don't work well at removing all the oil.

The MityVac attached to a small electric air compressor can suck the chrome off a trailer hitch, and remove all the oil from your engine (if you bother to move the plastic tube around a few times).

What in the world does the brand of vac used have to do with how much oil you get out. It's where the dipstick tube guides your insertion hose that determines this. If the unit creates proper suction then the oil is coming out regardless of unit brand. I can assure you after probably 7 years the pela is still working fine however I agree the Mity Vac is of superior quality as I own one of those also however of the add oil design as opposed to extract.

I am not talking about brand, I am talking about whether the oil extractor is designed to be hooked to air compressor to create suction. Not all MityVac's have that feature. I can assure you that the results of an extractor that is designed to work with an air compressor (even a small electric one) is far superior to one that works with a hand pump if you want to get ALL the oil out. Any hand pump extractor can get 80-90% of the oil out. All I can say is that you have to try it to understand the difference.

 

[Genesis5.0]

I have a 2015 with 5.0. How many quarts of oil will it take for a oil change with new filter change as well?
