With a 0w-30 weight oil, your only choice is synthetic. Option of this weight are still pretty slim.

 

My preferenses is Mobil1 oil. I have used the oil since 1976 and never had engine problems

 

Let's not over think this rather simple non-complex matter. Opinions regarding engine oil requirements are like ear lobes; everyone has at least two The automobile manufacturers hire engineers to figure these things out although the marketing/finance folks sometimes interfere. Read your owner's manual and abide by it regarding oil viscosity/grade and don't exceed the Normal Maintenance Schedule OCI. Like my 2021 N Line 2.5T engine your SF 2.5T calls for 0W-30 full synthetic which, as pointed out FishRamLion is not a readily available viscosity. I use Mobill1 0W-30 AFE purchased from NAPA Auto.
If your "local guy" is a dealer don't trust them to use the specified grade oil or fill the correct amount 6.13 US qt. Ask and verify!!
2021 Santa Fe Owners Manual (hyundaiusa.com)

 

CORRECTION: Page 2-12 of the Owner's Manual calls out 0W-20 for the G2.5T-GDi engine whereas page 2-14 calls out 0W-30. : "Requires grade engine oil. If a lower grade engine oil (mineral oil including Semi-synthetic) is used, then the engine oil and engine oil filter must be replaced as indicated for severe maintenance condition."
CONFUSING??!!

 

You get 6 free oil changes at the dealer with your 2021.

Why are you taking it to “your guy”?

 

Maybe your dealer supplements Hyundai's complimentary Maintenance which is as follows:
Hyundai vehicles that are eligible for Hyundai Complimentary Maintenance receive no-cost oil changes and tire rotations (at normal factory scheduled intervals for 3 years or 36,000 miles, whichever comes first) performed by Hyundai-trained technicians at normal service intervals (see vehicle owner’s manual for applicable maintenance intervals). Hyundai Complimentary Maintenance includes:

• Engine oil and filter changes using Hyundai genuine oil filters and Quaker State oil
• Tire rotations to ensure even tire wear

For routine maintenance I take my N Line to "your guy" who happens to be "me" DIY

 

Hyundai recommends Quaker State. Walmart has QS in both 0W-20 and 0W-30. I personally also think that Mobil 1 may be better, but if you document that you used Quaker State it's one more point if anything goes wrong.

 

I have also used Mobile 1 for as long as I can remember and never had an engine problem. My local dealer will use Valvoline full synthetic for the complimentary free oil changes. That is why I will use Valvoline when I change the oil between his oil changes. I would find out what your dealer will use and use that.

 

3 years complimentary oil changes with every vehicle deal uuhm... there always seems to be a draw back on dealers side that someone gets to be to good to be any good, for the everyday new vehicle owner that has just bought it. whats hyundai's oil change interval's? when does Hyundai expect you back? for next oil change.? & again hyundai with Quacker state oil i mentioned already on a other

post Quacker state has a contracted deal to use Quacker state Oil. win...win for both Quacker state & Hyundai. there oil filter is a good basic standard oil filter nothing special with it. use a fram XG Ultra much better since its a synthetic nano fiberglass beefier type media at filtering oil much better than oem.

 

Look at the oil filler cap, check the manual. As long as you follow the recommended change schedule, dino or synthetic is fine provided the proper weight is used. Synthetic might improve mpg. Synthetic has better numbers on paper, but dino oil will not wreck your engine.

 

Schedule the oil change with the dealer, sit in the lounge and have a cup of coffee, watch a little Jerry Springer (or Maury) and don’t worry too much about it. You might ask for them to use a synthetic, or synthetic blend, but you already seem to know that conventional oil is fine up to the 5k miles service interval. After all, it is a complimentary service through 36k miles.

 

I would go with 0w-30 or 0w-40 too

 

Can someone highlight what the tradeoff is between 0w-20 vs 30 or 40? I googled it but am still not quite sure what one is trading off going with 20 instead of 30 instead of 40. Tnx.

 

The 2nd number is the viscosity level when the oil is hot. A higher number means thicker, a lower number means thinner. You need to consider the typical temperature in your region. You need to consult the manual, it should have a chart of temperature and oil grade.

 

Turbo needs 0w30, not 0w20. Personally I would change the oil inbetween dealer oil changes and abide by the Severe Maintenance Schedule in your Owners Manual.

In other words, the dealer provides free oil and filter at the Maximum schedule and you should do oil changes inbetween that maximum schedule. That's when I would opt for 5w30 synthetic, when ''your guy'' does the work. 5w30 will better protect that new engine and perfect for your Virginia climate.
