Does it have to meet all 3 specs or any one of them?

I'm pretty sure I've seen Pennzoil Ultra 5W-40 Euro at AutoZone and Advance...

In fact the only two Ultra varieties my local AZ stocks are 0W-40 and 5W-40 Euro.

Why not Mobil 1 0W40? Cheap at Walmart, does well in my turbo cars...

On a side note, I can't use 0W-40 since I'm under warranty.
I'm planning on doing a used oil analysis on both 30 & 40 weight oil to see which on stands up to my driving conditions.


-Thanks

When you say "I can't use 0W-40 since I'm under warranty", it makes no sense at all. How would a heavy-duty-diesel-engine oil (5W-40) be OK in your gas-engine application while a gas-engine oil with virtually the same cold, hot, and high-shear viscosity but better extreme-cold viscosity wouldn't be OK?

If you want to use 40-weight oil, Mobil 1 0W-40 SN is the way to go, not a 5W-40 heavy-duty-diesel-engine (18-wheeler) oil.

Hyundai only list those 2 weights in the manual. The thing is the same engine is used in the Genesis Turbo and the manual recommends 0W-40. I suppose I could try it.

If you stay at 5K OCI's or less, I would just stay with Pennzoil Ultra 5W30... At 3.5 K oci's, you could use plain jane Pennzoil Conventional and be perfectly fine. Pennzoil Ultra at 5W30 is one of the best, if not the best, oils that you can buy...

You're asking the wrong question.
For that type of normal driving the lubrication demands of your engine would be better met with a syn' 5w30.
It's a common newbie mistake to think that because you may occasionally take the engine to red line on the street that you automatically need a heavier oil; you don't.

If 5W-40 is recommended but not 0W-40 for a gasoline engine, it's just a mistake or oversight by the guy who wrote the manual. Don't take it literally.

As other posters said, you don't really need xW-40 unless you drive very hard or tow. Lowest viscosity that is recommended is usually the way to go, especially for a new car. It will cause less strain on the oil pump due to lower oil pressure, better cold starts, and better fuel economy, without significantly affecting the wear.

My vote goes to Valvoline Synpower 5W-40.

+1. Are you going to use 5-40 in your Hyundai?

Yeah or 0w-40, I don't mind using 5w30 but I do drive hard sometimes. I just want to be sure Pennzoil Ultra or Quaker State Ultimate Durability (30) can stand up to abuse if I'm hard on the car.

...any one would suffice according to my correspondence with HyundaiUSA and two dealerships. ACEA being the least of their concerns.

Schaeffer 5w-40 is another top synthetic oil that will handle your abuse

Contrary to what any naysayers are telling you, any 5w-40 HDEO in SM or better does meet the manual requirements for your engine. You can use Rotella 5w-40 or Mobil 1 Turbo Diesel Truck just as easily as you could use some Valvoline, Pennzoil, or Royal Purple 5w-40.

If the automaker supplying the warranty isn't freaked out about it, neither should we be.

 

[Shannow]

Garak is, as usual right.

It's not like in the other thread manufacturers carrying the old CF diesel spec through their passenger car range, these fleet oils are maintaining current spark ignition ratings.

They are current, and compliant, and the manufacturer would have a hard time saying that their use would invlidate anything as long as the viscosity is appropriate to your vehicle.

 

[wemay]

+1 to Garak and Shannow.

 

[bigt61]

My vote goes to the cheapest full synthetic 5w30 you can find, probably SuperTech, if you insist on changing it at 3.5K. I'd stay with 5w30 unless you're racing your Sonata in some sort of Le Mans enduro.

These are somewhat contradictory specs. There is no ACEA A5 xW-40 oil.

What I can can infer from these specs is that the main recommendation is a fully synthetic xW-30. You can use 0W-40 or 5W-40 but do so only if you drive very hard or tow.

Just pick a quality, brand-name fully synthetic 5w30 ILSAC GF-5 oil and you will be fine. You need a fully synthetic oil because you have turbo. Stay away from store brands as sometimes they are of unacceptably poor quality. You can also use 0w30 if you are having cold-start problems in extremely cold weather, with possibly a little more oil evaporation from the turbo thanks to possibly higher NOACK.

There is no need for xW-40 or expensive low-SAPS ACEA Cx oils, as your manual don't call for them. The low-SAPS ACEA Cx oils are mainly for diesel engines with particulate filters -- they shouldn't be critical for gasoline direct-injection engines.

Interestingly enough Hyundai does not specify synthetic oil so any API 5w30 will do. I would suggest a 5w30 syn' nonetheless, even a store brand, and I know of no "unacceptably poor quality" syn' oils.
NYC doesn't see extremely cold temp's so there are no 0W-30s that would offer a starting advantage over the lightest 5w30s, consequently it need not be considered.
