Oil Change, 15,000 miles / 2 Years

[martyk]

I have a 2012, 4.6 Genesis. I am coming up to the 15,000 mile/ 2 years, oil change. I have used Synthetic oil, Mobil 1 Advanced Fuel Economy, 0W-30. But Genesis recommends 5W-20, or 5W-30. Should I change to 5W-20, or 5W-30? I’d appreciate your help in recommending the best synthetic oil, thanks in advance.

Mobil 1 0W-30 is a suitable replacement for 5W-30. I have used this oil many times on my Genesis V6. Be careful not to use a 0W-30 European Formula oil such as Castrol Syntec (it will say European Formula on the bottle). There are no conventional 0W oils that I know of, and Hyundai does not require a synthetic, so that is probably why they don't mention it (and also they don't want you using a European Formula oil).

I would not use a 0W-20 or 5W-20, especially on the 4.6 Tau engine, or even the GDI V6.

Unless you live where it gets to 30 below, and your car sits outside in that weather, the difference between 0w and 5w is insignificant.

5w30 or 5w40 in warm climates. 0w30 in cold climates. Mobil 1, Pennzoil Ultra, Castrol edge, Valvoline Synpower, are all excellent oils. Pick one and stay with it.

Mobil 1 0W-20 AFE and 0W-30 AFE are Advanced Fuel Economy formulas and have nothing to do with what temperature one lives in. These are the only viscosity that Mobil 1 AFE is available in. So I would not hesitate to recommend Mobil 1 0W-30 oil in even the warmest climates (compared to 5W-30).

The only 0W-30 synthetic that I know meets Hyundai specifications is Mobil 1 0W-30, since the others are European Formula oils that should not be used in the Genesis.

But I do agree that there are some other good brands of oil available, but most of them are 100% Group III synthetics, where Mobil 1 is typically (varies by product) at least 35% Group IV or V synthetics and the remainder is Group III. Pennzoil Ultra is probably an exception and similar to Mobil 1, but hard to come by and seems pretty expensive unless it is stocked at your local Walmart (most Walmarts do not seem to stock it anymore).

Pennzoil Platinum would be better for your car than Pennzoil Ultra. Without trying to explain it here, go to Pennzoil's website. They have a great tool to show you what you should use (assuming you want Pennzoil).

Just for fun I tried this site and it has some incorrect model info regarding Mercedes. says 210 series for e350 2007 model= incorrect.

Can you elaborate on that? I went to their site and used the Oil Selector and for a Genesis 2012 V8, it says:

• Premium Performance - Pennzoil Ultra 5W-20
• Recommended - Pennzoil Platinum SAE 5W-20
• Meets Requirements - Pennzoil SAE 5W-20

Are you looking at something different than above? If, please provide a link. If not, I think you are misinterpreting the info they provide, since they clearly state everywhere on their website that Pennzoil Ultra is equal to or better than Pennzoil Platinum in every category (except price).

Presented as fact?? Hmmm. My experience is quite the opposite with a 2012 R-Spec. Ultra 5-30: 1/2 qt. usage in 7,500 mi.; Platinum 5-30: 1 qt in 4,000 mi.; 5-20 Platinum (and Mobil 1): 1 qt. in 2,500 mi.

I see why you don't "want to explain it here."

The issue of what viscosity to use is complicated by the fact that Hyundai recommends 5W-20 in order to achieve better MPG ratings and meet CAFE targets, rather than is really best for engine longevity. But certainly, I have never seen anyone from SOPUS (Shell Oil Products US) ever claim that Pennzoil Platinum is a better oil than Ultra.

Hey martyk!

Hyundai prefers that you use 5W-20 motor oil for their 4.6L engines. Thus, we recommend using our Pennzoil Platinum or Ultra 5W-20. Both will give you unsurpassed protection in keeping your engine clean, protected from future wear, and resistance to mechanical breakdown (oil thinning) over the life of the oil change.

Many of us have come to the conclusion that the 5W-20 recommendation from Hyundai is so they can meet CAFE MPG requirements, rather than what is actually best for the engine. In particular, some Genesis 4.6L engine owners have solved their high oil consumption problems when switching to 5W-30, and most others have noticed less engine noise (including those a V6).

Since you work for Pennzoil, can I ask what the heck happened that most Walmart stores no longer carry Ultra? I guess a lot of brands have had problems competing with the 800 lb gorilla of synthetics (Mobil 1), but now that most Walmart stores don't stock it anymore, the price is much higher elsewhere, and that makes sales go down even more. Seems like a vicious cycle, and its too bad because I wanted to try it. I'll pass on Platinum, although it is a fine Group III synthetic.

FWIW I drive a 2013 R-spec, use Mobil 1 5w-20, and in Atlanta heat have never noticed any oil consumption between 5,000 mile oil changes.

I also used it in our 2003 Honda Accord V-6 and for 180,000 never noticed any oil consumption or engine issues whatsoever.

I think that most of the problems occurred for the 4.6L in 2012 MY. Hopefully they made a manufacturing line change and fixed the problem for your 2013.

I have never noticed any oil consumption in any car I have owned in the last 20 years, and was not suggesting that 5W-30 is generally needed to prevent oil consumption in automobile engines. A fair number of people on this forum who had excess oil consumption reported improvement when switching to 5W-30 (sometimes at the suggestion of a dealer). But clearly, no engine "should" use noticeable amounts of oil even with 5W-20.

However, even if there is no oil consumption with 5W-20, the question remains as to which one (5W-20 or 5W-30) is "better" for your engine, even at the expense of a slight loss of MPG. A few times I compromised and mixed 5W-20 and 5W-30 (same brand and type of oil) to effectively have a 5W-25.

For similar reasons, even though many people have not reported "problems" with conventional oil, I feel safe in believing that synthetic is better for my engine, even though it would be difficult to prove based on merely anecdotal evidence.

You're comparing potatoes and tennis shoes....... a 5.0 is NOT the same as the 4.6L.... that's all the explanation needed. gawd..... some peeps just don't have a life except to go on forums and hate on peeps trying to help out.

Additionally, the OP was asking about a Hyundai Geneis..... NOT a stinkin' money pit Benz...... duh!

Also, the OP has LOW mileage...... the Pennzoil Ultra is for "higher" mileage cars if you know how to read a chart........ again, peeps just make out of stuff what they want to in order to justify their existence on a forum that should be more about helping peeps instead of hating on others comments who are trying to do what the forum is designed. But, you guys are everywhere.... on every forum...... no exceptions here.

explanations my bug ole butt!!! bbbaaawwwwaaaaahhhhhhaaaaa

I agree that either 5w-20 or 5w-30 will do the job just fine; change intervals and driving habits are far more important. I do think it might be that 5w-20 might pump faster on startup and this is when about 98% of engine wear occurs. having said that I once owned a 1976 Olds Cutlass, put over 300,000 miles on it with conventional 10w-40 and never had any engine issues or oil consumption.

Have a good day.

what about Mobil 1, Advanced Fuel Economy, 0W-30.

That is an excellent oil, and a good choice for the Genesis. I have used it for most of the oil changes on my 2009 V6 Genesis.

One cannot compare conventional oil and synthetic oil at the "same" viscosity rating, because in actual use they are not the same, especially over time.

Also, although there is an issue with "some" 2012 Genesis R-Spec 5.0 engines with regard to oil consumption, that is an unusual situation relating to the engine, and not the oil. Even if a higher viscosity helps in these specific cases relating to the 2012 R-Spec 5.0, that does not mean that other engines will suffer oil consumption without a higher viscosity. No one said that.
