Hi. I was reading this post hoping to find an answer as to why when you add the called for 5.5 qts. of oil the dipstick shows at least .5 qts. past the top mark on the dipstick. Saw this posted earlier in this thread but saw no responses. Any ideas? 2011 3.8 V6. I had it changed at a garage and now did it myself with the same results. Dealer service manager says he's never heard of the problem.

Yes. There are some old threads on this problem. Dealer service managers are either don't know (service techs don't tell them) or are just lying. I will give your service manager the benefit of the doubt and say it is number one (techs don't tell him). But it is real and I have done extensive testing of the problem, trying all kinds of different ways to check the dipstick level in an attempt to figure it out (with oil filler cap off vs on, right after engine shut down vs wait at least 5 min, etc). One theory about this is that the oil filter on top of engine drains into crankcase very quickly after shutdown, making it appear that the oil level is over-filled.

When I change my oil, I use an oil suction pump inside the dipstick and move the drain tube around inside the crankcase to make sure I get as much oil as possible. When I do a thorough job of that, then I can put in 5.5 quarts and have the oil at the full level (not above that). But when oil is drained from the bottom, adding 5.5 quarts will cause the oil level to be much higher than the full mark on the dipstick.

The factory fill on my car was well above the full mark on my dipstick, so it sounds like Hyundai engineers don't even know what is going on. Questions to Hyundai dealers and to HMA have fallen on deaf ears. This is why Hyundai will never be a Toyota or Honda. They just don't give a damn.

So, from reading your reply it sounds like there is oil left in the crankcase after draining. That was one possibility I pondered. Also that's VERY interesting that you say the car "as delivered" showed a high oil level. Can't say that I ever checked mine when I first got it but wish now that I had. Funny how such a seemingly low tech issue can not be explained by Hyundai. I guess the obvious solution is to add only 5 quarts in the future. Now I can use that Fumoto valve I installed to remove the phantom 1/2 quart. Thanks for the excellent reply.

Maybe this issue is the reason Hyundai moved the oil filter to the more normal orientation on the bottom of the motor. Then that half quart stays out of the crankcase and the confusion goes away. Just a thought.

Possibly, or may have something to do with extra stuff needed for GDI, and they needed the space on top. I have not compared the old V6 with the V6 GDI to make a comment on that.

There is always oil left the crankcase after draining, especially when oil is drained through the drain plug (contrary to popular opinion). The question is: how much, and is that related to the discrepancy? No one seems to know if we are running 1/2 quart too high, just right, or 1/2 quart too low. As mentioned before, it could be that the extra oil in the crankcase when engine is shut off is needed to fill up the oil filter when engine is running.

HMA is too lazy or indifferent to ask someone in Korea for an explanation (I know because I contacted HMA).

Now that is what I call a write up, well done mate!

Nice post and very helpful pics--I have a 2012 Sedan and the oil filter mounts under the engine on the right side (pass side) of the oil pan/drain plug. When I removed the oil filter cap the place where the large 'o' ring installed was obvious. Then I removed the filter and looked all over the engine filter mount and the filter and the cap but could not find where the small 'o' ring would install. I assembled the filter and installed it with the new large 'o' ring and saw no leaks. Not sure if the small 'o' ring is installed on the newer design(under engine mounting.
Any ideas?

Small o-rings are for 2011 and older.

Are you guys using the Fumoto Valves on the Genesis Sedans?

I have a 2012 3.8 and am looking to install one one but am not sure if the long nipple type is going to fit fine under the engine cover or cause fitment issues:

Regular Nipple $26.64:

Without the Nipple $23.50:

I have been using these on my other cars and has helped a lot and have not caused any issues.

I tried to install one but with the way the threads were started, the valve body ended up sticking down, lower than the oil pan. Could have presented a problem and cause significant damage to the oil pan, or be ripped off. Didn't chance it and returned it.

Philth,

Thanks for the reply and is your car a 2012?

So for the 2012 what I understand is that we have a cover that goes underneath so that being the case we should be able to put the valve and even if it comes down an inch or so it should be fine as there are other components in the back that are lower. I doubt that it will be that much lower, the nipple that is. The Fumoto website actually also has a short nipple version so that might be a better compromise. The reason for the nipple is to have a tube connected to reduce the mess and the other reason is that you can stream the oil at a better angle if not using a tube.

I did my first oil change this weekend and did end up using the fumoto valve. No real issues as it fit back up in the cutout and wasnt sticking out any more than usual. Could have even used the longer nipple won without issues.

Re: 2012, 3.8 V6 Genesis Sedan

Nice oil change write-up.

Does anyone know if the 2012 V6 takes the same oil filter?

On the 2012, the oil filter is not on the top, rear of the engine its underneath, at the front of the motor, on the passenger side. It will require removal of a skid plate underneath to change the filter.

Funny thing is there is still a hole in the skid plate for access to the drain plug. This is the skid plate which needs to be removed to access the oil filter. Unless you are changing oil and not replacing the filter the hole seems unnecessary unless you want to be able to check for leaks.

REVIVE OLLLLLD THREAD
I got sick of paying the dealership so I did my oil change today. How about there is no skid plate under my car!!
Why? I got right under there and changed the oil FAST as heck. another thing, I put in 6 QUARTS by accident. Will I be ok?
I will check the levels in a few minutes. I got the Mobil 1 5W30 EXTENDED life since I have 118k miles.
Any advice would be great.

Thanks

Not sure if you have Mobil 1 Extended Performance (which is good for an engine regardless of mileage), or Mobil 1 High Mileage (which they sometimes "claim" is for cars over 75K miles).

If you used Mobil 1 Extended Performance, you are good shape with a quality oil.

If you used Mobil 1 High Mileage (or any other brand "High Mileage" oil) then it may be a problem. High Mileage oil should not be used based on the number of miles on the engine, but based on whether the engine is using oil between changes. If your engine does not use oil between oil changes, then High Mileage is not good because it contains chemicals to swell the seals to help prevent excess usage or leaks. Once you start using High Mileage oil, the seals may be permanently changed and it could cause problems if you started using an oil that was not High Mileage oil (the engine may start leaking oil, even if it did not before).

Moral of the story: Never use a high mileage oil solely based on the number of miles on the engine. NEVER.

Thanks for the reply. It is the Mobile 1 extended performance. YUP. i gave the incorrect viscosity, it is 10w30 not 5w30. I went by recommendations on the boards since it is hot (90+ here in the Carolinas). Again, the dip stick is showing a little over since I accidentally put in 6 quarts. I did however eliminate some of the car's vibration at idle but I would like for it to not feel like a HONDA that has over 100k miles and vibrating period.

Did I mention my shield under that bottom was missing? I think the stealer-ship did not put it back at ALL. What should I do? I cannot prove it 100%.

Not sure what boards you are talking about, but at next oil change I would switch to 5W-30. Both 5W-30 and 10W-30 have almost the same viscosity at normal operating temperatures, but 5W-30 is better for cold engine starting (where a significant percentage of engine wear takes place).

I just looked back at my recycling bin. It is 5W-30. SIGH. Im sorry about that.

I have always had the dealer do the oil changes but will do them myself going forward.
I have changed oil many times but have one question on the top mounted filter on my 2011.
Is it obvious where the little "o" ring goes?
The very good write up says at the bottom of the stick.
Can anyone show me a picture or explain where it is located
many thanks
