What does your owners manual say about oil quantity for drain and fill? On my 2009 V6, it is 5.5 quarts, but many people report that only 5 quarts are needed according to dipstick. 2012 may be different due to filter moved to bottom of engine.

Synthetic 5W-30 or 0W-30 is good choice.

The info on the car symbol is in section 4 and 5 of your owner's manual. Everyone should read and study the manual to know all the features and functions of the Genesis.

2012 3.8 Genesis. now with 21,000 Miles. I've had 4 oil changes, all performed by the selling Hyundai dealer. In all cases, they used 5 W 20 weight oil instead of the called for oil, 5 or 10 W 30. The car has been used in very hot weather. Have they damaged or hurt the long term viability of this engine?

In a word mstrubbe NO. See BobistheoilGuy.com and in particular the "MOTOR OIL UNIVERSITY" portion. 20 minutes of light reading and you will not think the same about motor oil again. I too have the 5W-20 grade of oil installed by the dealer and I'm perfectly happy with it and have no fear of the oil ruining the engine.

I would not go so far as to say that his engine is ruined because the dealer put in 5W-20 instead of 5W-30, but I would not say that they are equal in that particular application.

I know that in the 2009-2011 Genesis models (V6 and V8) Hyundai recommended 5W-20 oil. Apparently, starting in 2012 (I am taking OP word for this since I don't personally know) when Hyundai introduced the GDI versions of the engines, they now recommend 5W-30. Why did they do that? We are pretty sure that Hyundai can claim better MPG with 5W-20 oil, and that CAFE numbers are very important to Hyundai (and other automakers), so one has to assume that if they did change the recommendation to 5W-30 that there was some good reason for them to do that, which most likely involves better engine life/reliability at the expense of slightly worse MPG.

Besides that, BITOG is a cesspool of rumors and folklore, and I would follow the Hyundai Motor America recommendations over what the dealer or BITOG forum says.

I will admit that in some engines one can use either 5W-20 or 5W-30 without much concern as which one is used, but when the manufacturer changes their recommendation from 5W-20 to 5W-30 I would follow their advice.

I've only read the "motor oil university" plus a few articles. You, Mark, must mean the forum section of the website. " Cesspool " hmm I assume you mean the site contains unfounded, erroneous, or even purposefully harmful info. You might have a point. However, the info in the university and in particular the subject of viscosity I find to be very informative. You can't go wrong sticking to the Hyundai recommendation. I'd like to hear their rationale for the recommended oil.

Any where there is a public forum there will be erroneous and unfounded information. It's the nature of the beast. To think there is no misinformation here is ludicrous. Some peeps even contradict themselves.

I think there are several problems with discussions about motor oil (especially on BITOG):

1. Some people are religious about motor oil, and are born-into a particular brand and stay with it for the rest of their lives. You would be safer bashing their religion than their choice of motor oil.
2. Some people favor boutique or other obscure brands that have lots of folklore, even if the boutique companies get their components from a major oil company and just pour dye into the oil to make it unique. The more obscure the brand, the more some love it, even though actual production of motor oil is now done by fewer and fewer very large companies.
3. Many people don't understand that oil companies are sold, merge, or now outsource much or all of the production of their products. Many brands are just marketing companies that sell someone else's oil (even if they used to make their motor oil). Things are not the same as they were 25 years ago, but the old beliefs die hard.
4. Some people easily fall victim to bait and switch tactics, such as Amsoil, which publishes tests on their extremely expensive non-API certified oil (non certified because it will damage your emissions system), and then sell their cheaper API Certified oil that is no better than what you can get for half the price just about anywhere else.
5. Rumors are unsubstantiated, and then repeated as fact somewhere else. When someone asks for proof and you trace it back to the source, it ends up being one big circular rumor mill.

I run Mobil One which rates pretty darned good, and others (but not all) rate well. It's good enough to be factory fill for AMG, Porsche, and Corvettes, so it goes in everything I own except my bikes/ATV's.

That's quite a comprehensive list with loads of information, but, how does one interpret it?

Good question. Plus, if one were to compare the specs of a 5W-30 and 5W-20(or 10W-30) of the same brand, "many" of the specs would be noticeably different, much more different than the difference between brands of the same viscosity (in most cases).

Then you have trade-offs between engine protection and better mileage (energy conserving formulas). Also trade-offs between wear protection and federal compliance with emissions systems (some additives that produce less engine wear may damage an emissions system).

But in any case, someone using a decent quality full synthetic is way ahead of the game compared to conventional oils. But there are some differences between synthetic components, such as Group III (hydrocracked mineral oil), Group IV (PAO), or Group V (esters). Most of the "premium" synthetics these days are blends of Group III and IV/V components. But Group III technology has improved in recent years and in many respects these oils are almost as good as those with significant Group IV/V components.
