2021 Limited 1.6T, 2018 Limited 2.4L, 2015 Limited 2.4L
Full Synthetic, 0W-20 Quakerstate, every 5,000 miles
FWIW, I just had the first “free” dealer oil change for my 2020 hybrid (7400 miles - manual recommends 7500). 0W-16 recommended for the 2.0L hybrid. I looked at the oil on the dipstick before taking it in - it still looked like honey - almost no darkening.I have a 2013 Hyundai Sonata GL and I’ve never owned a car where the crankcase looks so dirty after Every (synthetic) oil change, so frustratin!
Change to the newest oils with API SP ILSAC GF6A oils. There are 7 new tests which are very difficult to pass. The full version of this test requirements were released Dec. 2020. Many oils have failed the 7 tests.i think we need to get clarification on oil change intervals, and type. i know this has already been discussed, but there seems to be different answers depending on what dealer i spoke to. this applies to 1.6t engine. 2020 handbook says oci 6k. 2021 says 8k. when i called the dealers back in 2020, both said cars come with syn blend, and that is what they put back in. now, one dealer says the same thing, another dealer says there was a bulletin back in march(when we got our car) that put the intervals back to 6k for all years, and full synthetic. he also said what they put in is 5w-30. the other dealer, where we got the car, is smaller. the tech/adviser i spoke to said they have not yet serviced any 2021(or maybe he said any 1.6t) cars, and he would check with his tech. while i dont care for the dealer that told me full synthetic, 5w-30, i would take my car there for the free service, otherwise, i just take it to a local independent. which i have already done, twice. of course, calling hyundai customer service does nothing, all they say is ask my local dealer. when i tell them what the 2 dealers said, all i get is , "huh?" so, if anyone else calls their dealer, post back here what is said.
The new ILSAC GF6B or 0w-16 oils have passed very stringent 7+ new tests. Hyundai factory oils have passed the new API SP / ILSAC GF6A and GF6B. These oils have very sophisticated Total Base Number (resist acidification from ethanol fuel additives) and anti-wear components. This oil have passed, improving timing chain life, reduce volitility (old oils standard allowed 9%-13% wt lost in 1 hr, 250 C test), address LSPI - Low Speed Pre-Ignition, lower carbon and sludge build-up, lower cold (-30C) crank viscosity for cold start protection, more high temperature stability, etc..FWIW, I just had the first “free” dealer oil change for my 2020 hybrid (7400 miles - manual recommends 7500). 0W-16 recommended for the 2.0L hybrid.

Didn't you already post this 9,999,999 times on this site? Good grief.Change to the newest oils with API SP ILSAC GF6A oils. There are 7 new tests which are very difficult to pass. The full version of this test requirements were released Dec. 2020. Many oils have failed the 7 tests.
Hyundai/Kia/Genesis belong to ILSAC - International Lubricant Standard and Approval Committee org. The Hyundai factory oil have passed API SP / ILSAC GF6A and GF6B Tests and are certified.
Not all engine oils are created equal. Not all synthetic oil are created equal. Older oils (including Synthetics) have lost 9%-13% wt when exposed to 1 hr 250 C test, or lost 1/2 qt out of 5 qt oil in 1 hr., 250 C test. This contributed to carbon build-up, oil consumption and LSPI - Low Speed Pre-Ignition. (Data from PQIA, compared API SP vs SN vs SL). The new oils were tested to increase the Timing Chain life, reduce carbon, reduce sludge, lower cold temperature (-30 C) cranking viscosity, address LSPI, etc..
(Source of Data, PQIA). A company which passed the API SP / ILSAC GF6A is Warren Distribution. They blend oil for Costco Kirkland full syn, Walmart SuperTech full syn, AutoZone full syn, ORiely full syn, etc. The cold start viscosity for older oils were over 5,500 cp and the new API SP oils improved the cold weather protection by lowering cold crank viscosity to 3,800 cp. Costco Kirkland 5w-30 full syn is $24.95 for 10 Qts, Walmart 5w-30 full syn is $14.95 for 5 qt. Walmart full syn oil change is $49.95.
The best way to determine which oil is best is to use API (American Petroleum Institute org), ILSAC (International Lubricant Standard and Approval Committee org) and PQIA (Petroleum Quality Institute of America) Please read the label. Oil companies have until April 2021. After that date they get decertified and cannot use API certified star.
I will continue to post the new oil specifications API SP ILSAC GF 6A and GF6B, as long as “Used Oil Collectors”, silly annual oil change advocates, wrong oil advocates, diesel oil advocates, old single grade oil advocates are posting recommendations which damage our Hyundai engines.Didn't you already post this 9,999,999 times on this site? Good grief.
Both you and Gaz have advocated diesel oils which damage Hyundai gas engines. People on this forum need to know your decrepit scam to damage Hyundai engines.Idiots posting idiot stuff trying to look smart
I certainly hope a strong gust of wind doesn't knock you off your horse. I couldn't imagine a world without the Almighty Ray's sermons on motor oil.I will continue to post the new oil specifications API SP ILSAC GF 6A and GF6B, as long as “Used Oil Collectors”, silly annual oil change advocates, wrong oil advocates, diesel oil advocates, old single grade oil advocates are posting recommendations which damage our Hyundai engines.
Understood... editing my post. And will delete the content. I really found something in discussion. But can agree with you. For me all this is brain wash. I don't used to this. Sorry.I dont understand. The maintenance guide that comes with the car explains everything and is very clear and not at all complex.
You must abide by the lease maintenance requirements, if any, and the owners manual to maintain warranty coverage. Miles/KM or time, whichever comes 1st, isnt rocket science.
That redflagdeals site is popping up in tech/auto forums everywhere. Sorry, not going there and useless info too. Why are many are trying to drum up members and traffic to that site???
