Oil Consumption in '12 R-Spec

[Mark_888]

And as for your over exagrated oil consumption usage, there are only a hand full of us who have reported it, out of how many 5.0's that are out there? That's what, maybe 2% of them?

I hope you are correct and only a few people have this oil consumption problem. When I read the first report in this forum about it, I assumed it was isolated to that one member, since I have never read one post since Jan 2009 about any oil consumption problems with the Tau V8.

But after reading about more members who have this problem (and that some have the problem and didn't even realize it until they read this thread), and Hyundai telling customers that it is normal, then alarms start going off. So now I am am suspecting that I was initially wrong about it being an isolated problem caused by customer abuse of the engine. Maybe Hyundai knows about the problem and fixed it for newer production runs, but that still leaves some owners in a quandary unless Hyundai is willing to repair their engines.

I haven't heard of any oil consumption problems with the Hyundai 3.8 GDI engine, so I would not have a problem with that engine. So I don't have any hysteria about GDI. I have previously noted that a lot of people complain about extra soot on their Genesis tailpipe compared to non-GDI engines, but that is not a deal-breaker for most people (although maybe not a good idea to get a white car with Hyundai GDI unless you want to regularly clean the rear bumper).

If your R-Spec 5.0 GDI doesn't use any oil, then maybe there is hope that the problem was a short-term production problem and that not all engines are affected by the oil consumption problem. But apparently Hyundai is saying that the high oil consumption is "normal" and is not intending to do anything about it. Whether or not Hyundai will repair those engines with the problem (probably a very expensive repair), or whether they expect people to keep adding oil, is what I would worry about.

Another thing that would worry me (if I owned a 5.0 GDI) is that some are now saying there is significant condensation in the crankcase that masks the true amount of oil that is being used, so maybe not everyone who has high oil consumption knows about it.

In any case, I think Hyundai needs to step up and get to the bottom of this situation and fix it.

I agree that Hyundai needs to step up. However, dealers'/manufacturers' claims of "normal" happen a lot. For example, BMW says the excessive oil consumption of their N63 V8 (7-Series) is normal, although its often 1qt/1500 miles. That truly is a design issue, although many variables are at play, including how the car is broken in.

Condensation is largely a behavioral/short trip issue. Witness the circa 2004 3.0 liter I6 BMW engines (M54 series) that blew their valve cover gaskets, spewing yellow sludge and oil out due to uninsulated crankcase ventilation tube that had frozen (condensation) in northern climates - specifically caused by oil that never warmed up - again and again. I have experience with that! BMW later offered a cold-climate replacement part. Short- trip condensation build-up, not compensated for with some trips of 50 miles every so often, plus shorter duration oil changes will harm all engines, not just GDI designs.

I never said that condensation was only a problem with GDI engines. The only thing I have read about with regard to potential GDI problems is fuel dilution (fuel gets into the oil much more often with GDI than with regular FI engines), and that frequent oil changes with synthetic oil is recommended because of that.

I have also never heard any association between GDI and high oil consumption, other than what is specific to the R-Spec 5.0 in this thread. Not sure if anyone with a Equus 5.0 or regular Genesis (non-R-Spec) 5.0 is having the same oil consumption problems, or if it is limited to the R-Spec version of the 5.0. I don't even know if it related to GDI or not. The point is that, contrary to what I first thought, it seems that quite a few are experiencing this high oil consumption, to the point where Hyundai is saying it is normal.

I think we should limit the speculation on what Hyundai thinks is 'normal'.... as I'm sure HMA has much better grasp on the statistical analysis / failure rate of the TAU motor (4.6 and 5.0 mill) then any user on this board.

I would also assume so, but some people have reported that their dealer told them that such high oil consumption is "normal." That could mean one of two things (neither one is good):

1. There is a pervasive problem and the high oil consumption really is "normal" (or at least common) and therefore Hyundai will not fix it.
2. Only a very few owners have the problem, but they are being told that Hyundai will not fix it because it is "normal" even though it is not normal.

If a Hyundai owner has the high oil consumption problem and Hyundai will not fix it, then it doesn't really make much difference as to which one of the above is the case.

Thanks to this thread I checked my oil and discovered that it was over 2 quarts low. I had the oil changed at 3400 miles and had 7900 miles when I checked it yesterday. Alarming to use 2+ qts. in 4500 miles. I went to my Hyundai dealer this morning and, after explaining the situation, the service advisor said that they had not encountered any oil consumption problems. The oil has been changed and no oil leaks were found. The service advisor has placed my car on an oil monitoring program and instructed me to bring the car directly to the dealership if I discover any oil usage. Again, thanks to the OP for bringing this issue to this board. I feel more at ease and protected now that the problem has been entered into the Hyundai system. I will now begin checking my oil level at least once a week.

Most, if not all, manufacturers will state that the loss of a quart of oil between oil changes is not excessive. I agree, especially with regard to high performance high revving engines.

It's clear here that some members have a hard on for R-Specs. The constant bitching about the GDI 5.0 and the R-Spec suspension is getting old. Fact is no car is perfect, and that holds equally true for the Genesis. While some express that a 429 HP Genesis is too much, for me, and I suspect others, the 5.0 power was one of the attractions.

I'm hopeful that all of the Genesis owners on this board, and everywhere, are happy with their vehicles. I know I am, with the exception of my rear bumper center chrome strip, which has a wrinkled area about 5 inches long, and my shift knob which has an area where the black color is gone. (It's going in for repair as soon as I have time)

Wishes of Merry Christmas and a Happy New Year to all.

Peace

John

John - I could have not said it better! The only car in my experience that rivals this one was my 79 MB 6.9, and in its time, that was the quickest production bank vault on the planet.

I have been fortunate to have owned a number of fast, powerful and sporty cars in my lifetime. For a high end, powerful and sporty sedan, the R-Spec for the dollar cannot be beat. I have been extremely happy with my R-Spec since I purchased it in July. Other than this concern with oil consumption, the only thing that I wish my car had was an even more powerful engine along the line of a CTS-V. I owned a 2009 Cadillac CTS direct injection before my R-Spec and never had any problem with the engine. Of course that does not mean that the 5.0 Hyundai V-8 will not/does not have a problem. This remains to be seen. At this juncture, I think this is a great engine that combines power with good economy.

John, I agree with you and both me and the misses love our R Spec. Matter of fact, when I said something to her yesterday about the oil consumption, her answer was " I don't care if you have to keep putting oil in it. Do what you have to but we are not getting rid of the car. "

Even after seeing this thread, I hadn't thought much about the oil until my oil light came on briefly and I found that I was 2 + qts low. That just means I need to start checking my oil more often. And yes, I bought the car not only for it's looks but for the 429 HP as well.

I think the car being two quarts low means Hyundai better order you a new engine under warranty. I would never put up with any new car using oil, much less put up with a $40,000+ car using oil. Why be so passive?

 

[Crusty Old Shellback]

I plan on keeping an eye on it and have already reported to my service advisor and will continue to do so if need be. I agree that it's a hassle. But hey, it's got a 100K warrenty so if something goes bad due to no fault of mine, it gets replaced.

I've had a lot worse problems with other new cars.

Quick update - I read through the service documents, and they refilled my oil with 5w-30 instead of 5w-20 this time. Consumption seems to be a little slower, but over 600 miles it looks like I'm still down about a 1/3 of total capacity, according to my dipstick reading. At this rate, I will be back to the dealer in early January to register the consumption.

i have to say again that my 2011 4.6 with 77k+ miles has never used oil or been low with 5000 mile oil change services. Also my Suburban with 350cid v8 has never used oil in 172,000 miles.

You mean 1/3 of 7+ quarts (or 2 quarts) or 1/3 of the way to the "add oil" mark??

Just had my oil change at my local southern california hyundai dealer and they to used castrol 5w30 edge syntec oil. The service tech also gave me a heads stating that they charge all r-spec 5.0 vehicle owners for 8qts oil because they put 7qts in the vehicle and then run it for a bit. Then they recheck the oil level and some vehicles will need a bit more than a half quart-hence that's why they charge for 8qts. After researching the castrol oil here's what I found on castrol site as one of the oils for our vehicle (5w30 edge syntec oil):

"CASTROL EDGE, SAE 5W-30
SL, SM, API* 5W-30 - AN ADVANCED PROPRIETARY FORMULA THAT PROVIDES PERFORMANCE AND PROTECTION IN EXTREME CONDITIONS SUCH AS TOWING, HAULING, HIGH AND LOW TEMPERATURES, RAPID ACCELERATION AND STOP AND GO TRAFFIC." http://www.castrol.com/castrol/LubesSelector.do

I definitely meet the requirement of "rapid acceleration and stop and go traffic." Again I am old school and check my oil every time I fill up my gas tank and sometimes after I run her really hard as I put her in the barn wet.

How much oil does your R-Spec use between oil changes?

How much oil does your R-Spec use between oil changes?

The first oil change was completed at 3000 miles by the dealer (It was the owners vehicle). I purchased it at 3300 miles. Yesterday when I had my first oil change it had almost 6500 miles. It's two months that I've owned it and from my monitoring I have not had to add oil. Like I've mentioned in prior posts I check my oil at every fill up now. However the first month I actually check it daily. I do this on all my new vehicles (after break in period or miles) as it gives me good feel of how much oil is going to be used between oil changes. And I've owned several new vehicles over the years (bmw,toyota,ford,subaru,honda) and actually had two that were definitely using oil between oil changes. I plan on doing the next oil change at around 13k. If I find that it uses oil between oil changes I will let you all know. FWIW-I drive the vehicle daily to work about 35 miles round trip and about 50% of these miles are stop and go traffic. On week ends I tend eb and flow on the miles but I tend to go out on highways or freeways that safely afford faster driving speeds. FYI-the bmw and subaru were using about 1qt between oil changes (appr. 6000K). A tip to those iding oil usage I would recommend keeping a log book for your vehicle. I keep one in the glove box, doesn't have to be anything fancy but use it to record information and you would be surprised what you learn and what can be correlated to iding issues. I was a pilot and A/P student in my youth in college and old habits are hard to kick as we always had to complete our pre-flight which included checking the oil every time you flew those old 150s and logging into your log book.

Suuure it was.

Okie, dokie.
