Added note: Valvoline chose not to "certify" their oil because of cost, JUST as Redline and Amsoil has chosen to do the same, not certify, while exceeding the certified minimums.
Flack from the oil wars: Tom Read, a spokesperson for GM's powertrain technology group, warns that using an alternative oil might diminish performance.
"If a customer uses a non-licensed engine oil that is simply ILSAC GF-5 quality, they will not enjoy the benefits of using a Dexos-licensed product," Read says. Those benefits could include better low-temperature performance, cleaner pistons and better aeration performance, he says. "This could be especially important as the engine oil ages."
Read's case for Dexos sounds compelling, but Valvoline's Smith isn't buying it.
"Our SynPower 5W-20, 5W-30 and DuraBlend 5W-30 went through all the Dexos testing and passed all the requirements," Smith says. "But we felt that carrying the Dexos name was not providing the consumer with any value."
Rather than raise the price of its oil to offset the cost of licensing the Dexos name, Valvoline chose to forgo the license and keep the prices lower, he says.
Smith says that GM's engine-performance warnings are part of its goal to drive consumers to dealerships for their maintenance. "We feel that they are taking choice away from the consumer," he says. Focus on the Oil Basics
Setting aside the claims and counter-claims of manufacturer-specified oil superiority, here's all you have to remember: As long as you follow the oil specifications shown in your owner's manual, you have nothing to worry about.
In the event that the dealership tries to void your warranty over the use of non-manufacturer oil, know that the Magnuson-Moss Warranty Act will protect you. If your vehicle doesn't have an oil specification, you have more flexibility in choosing your product. Finally, make sure you know the proper viscosity for your car and change the oil at the proper interval.
Added Added Note: I read somewhere that Valvoline now certifies those oils and is charging you more for that cert.
While I stated this is some of it's form above, I thought I would add this from another forum, since typing time and another opinion can be useful when hashing over oil choice and warranty manipulation by dealers and manufactures.
If you live in the USA you have the Magnuson-Moss Warranty Act that gives you protection from the manufacture abuse, and in almost all cases, dealer abuse (since some don't know the law). Some try to pack crap up you rear end , but the minute you bring up your rights with the Magnusen-Moss Warranty Act they back right back down with their rhetoric game. Some don't even know there are laws protecting the car buyer.
First you most likely have oil viscosity options. Like in my 2018 Hyundai Kona turbo, 5-30 is spec and 5-40 is an option if no 5-30 is available. Sorry Hyundai 5-40 is a far better oil viscosity for a steaming hot turbo then 5-30 and they know it. Most of the time the key word is "recommended" and not "must use". I live in Minnesota and we see 30 below from time to time, I will be running 0-40 in the summer and 0-30 in the winter. In a turbo GDI with fuel dilution issues, and my rough service use, I want a 40 weight oil that will HOLD the spec of the 30 weight when it is sheared down from use and fuel dilution. I myself will never run a 0-20 or 5-20 oil. Now they are pushing 0-16 and 5-16 oil. Sorry you can take your CAFE standard water oil and stick it ..... I want some oil that can hold a oil film boundary layer when pushing the motor in high rpms or severe heat. I don't care about the manufacture 's mandate for CAFE mileage figures. You see these same cars ( high performance ) use 5-40 and 5-50 in Europe and other countries because they still think they need to use the "proper" weight oil for the use case, and not to meet some government CAFE standard BS figure. But even they are getting bully wipped into following their form of CAFE standard at the determent of the engine.
As far as the manufacture, most if not all they look for is if you have oil in the car and not red ATF or gear oil in your engine crankcase. Or engine oil in your gearbox, ATF in your CVT trans. Example: I have a relatives in both the largest Audi dealer and the largest Lexus dealer in Minnesota. Both have never taken and oil anaysis of any blown up engine for the last 10 years both have been working at prospective places. All they check for is proper oil for the proper location, No red oil in the engine oil ( ATF) and they smell for gear(hypoid) oil in the engine, other wise the warranty goes through as it should.
I have talked to both Amsoil and Redline about this and they get a couple "dealers" who strong arm customers and deny warranty on oil and say it was "the oil" that caused the problem. Never the manufacture.....WHY, because the manufacture KNOWS about the Magnusen-Moss Warranty Act and knows the customer has rights and there for doesn't, in almost all cases (in the USA) try to screw the customer with a sweeping generality of denying warranty on falsehoods. Now a days the oil is so far superior even in cheap name brand dino oils that oil is really never an oil issue. It's a design and manufacturing issue. Because part of the law is the dealer or manufacture has to PROVE the failure, YOU done have to prove anything. Other them is a rogue dealer who is clueless to the law tries to push you around, you just have to push back.
Example: I owned a 2013 Elantra GT 1.8 liter. I use Fram's best oil filter, the Fram Ultra, a completely different filter design from the other cheap junk Fram makes and that has the bad rap. The Fram Ultra high quality fully synthetic filter, that is in the top 5 best oil filters made.
I brought my car in at 14,000 miles with the Hyundai tick of death, they told me 2 separate times this is normal. They said I SHOULD use Hyundai oil filters, they found that other aftermarket brands can exacerbate this problem. They pulled the Ultra and put their OEM "swiss cheese" filter on and still the same loud ticking noise. Still, I get this is normal. Being I have had years of engine building and owned a hobby Audi repair shop I know that this is not a normal sounding engine. On the third time in with this sound I said "here are the keys and I don't want the car back until you fix the problem, this is not "normal". 4 hours later, I get a phone call saying I will be getting a new engine. So just because they tell you it is so, doesn't mean it is so.
Added note: Fram saw an issue with Hyundai motors and their filters so about 5 to 8 years ago they redesigned their filter that are speced to the Hyundai's to match or exceed flow and increased the can thickness to compensate for Hyundai's higher oil pressure they use to "compensate" for badly designed engines they have been known for. So I have zero issue using a Fram Ultra on my Hyundai's. In fact I bought my Hyundai Kona Turbo with 16 miles on it and I went directly home and took off the swiss cheese OEM filter and spun on a Fram Ultra at 32 miles on the engine. Any issue Hyundai.... I have Fram's R&D engineers and all their month long documentation this Fram Ultra exceeds Hyundai's own crap swiss cheese filter and my Fram filters my oil to far better degree then the OEM. No warranty issue because the Magnusen-Moss Warranty Act stated by law, I can switch out my filter or if THEY state I must use theirs, they have to give it to me for FREE. This stops proprietary common use parts gouging like filters, tires, oil, and ect....
Fram Ultra and the exclusive Fram Titanium at Advanced Auto are the only Fram's I would run. I am running the Titanium now. I bought 6 of them and the manager dropped the price down to $9.xx. The Fram Ultra speced for the Hyundai was brought back to get redesigned about 5 years ago to increase the can thickness and change the gasket and match the by=pass valve closer to the OEM Hyundai filter. Fram's customer facing rep told me the Ultra flows better then the OEM filter since it is a semi-embedding filter that lets a particle embed deeper in the filter material vs the OEM with a paper filter that acts like a screen door screen and slows flow after "caking" on top of the so called screen door screen.
The Titanium is the exact same as the Ultra except it has a better gasket and the holes that go arounf the main center threaded port are a lot larger then the small ones on the Ultra. Fram advertises the holes on the Titanium are tear dropped and increase flow. Just marketing BS, the increased hole size increased flow. You will be fine with both, but if they cost the same, I will default to the Titanium's everyday.
I called the dealer yesterday to schedule my first oil change, I am currently sitting at just under 2k miles. I asked what oil they used and they stated conventional so I opted to upgrade to synthetic, they also stated they no longer use 5-30 as the standard and it is now 5-20 or maybe she had even said 0-20. I guess this just came in from Hyundai corporate as the new standard viscosity.
Any thoughts? I may just take it to my cousins shop for the first change and put my own oil and filter in. Im sure the dealer will charge a pretty penny for a synthetic oil change. My Kona also came with a complimentary 3 year maintenance but apparently its only good for one oil change a year or every 7000 miles and its also just conventional.
Is Hyundai just being cheap with the oil recommendations or were these engines designed to run on conventional 5-20?
If you have a turbo, my opinion is "don't do it". Call another Hyundai dealer and ask them if 5w-20 is what Hyundai is stating is the new oil IF you have a turbo. I don't think that person was right. Hyundai's need thicker with questionable internal engine metallurgy and oil boundary layer issues. I myself would only use 5w-30 in all cars as a default viscosity. I have a feeling you received the wrong advice from whoever you talked to. I think they just do mot want to carry 5-30 since most of there cars are non turbo, which is a dis service to their turbo customers. They SHOULD be knowledgeable enough to know their turbo engines have fuel dilution issues and watering down oil with fuel is even worse with thinner oil. So many clueless people working at dealerships these days. Even some service managers are clueless on some things that years ago they would not be.
I think I did a full synthetic oil change with my dealer for my car's first oil change. When I got the receipt of work performed, mine said they put in 5w-20 as well. I then switched and did my own maintenance because I didn't want to pay $70+, and the oil cap says 5w-30.
I’m going into the dealership today for my first oil change at 2000 miles. I had to “upgrade” to synthetic and specify 5-30 Quaker state full synthetic. The service representative was a bit rude when I asked what kind of synthetic they use and why they opt for 5-20 over the recommended 5-30. If I didn’t ask they would of put conventional 5-20 in so I’m glad I inquired further. She was good at making me feel stupid , not the best customer service. Now I’m not quite sure I trust this dealership and may look for a new one. They also specify my complimentary maintenance is only at 7500 miles, the Hyundai app states 6k with my driving habits. She was also offended when I asked about what kind of filters they use , I just wanted to make sure they were OEM Hyundai as I have heard about dealerships using cheap bulk filters.
Anyways I’m happy to get this first change over with and get a solid base with a synthetic now that my engine is most likely broken in. I’ll go back at 7500 for my complimentary which includes the tire rotation.
I wish I was there, I would of reversed the rolls on that conversation. I just can't believe Hyundai doesn't have training with their front line people. Cheap 5w-20 in a turbo car is really stupid. Hyundai has a far amount of turbo cars in the the last 5 years, they should be 110% educated on something as simple as oil spec for a car. It is just the culture at Hyundai dealerships that they have not educated their employees as they should. I would still not trust they put in the right oil because they always default to 5w-20 that is about all they have. Most dealerships would love to upsell you to a more expensive oil for more profit IF they had it. Again, I always stated if you can't trust your Hyundai dealership go to a clean higher end looking (not a dumpy looking ) VW or BMW privateer import repair shop to have it done. You will have a lot less push back and they most likely have the oil in stock. It is good you ask questions and demanded what you want, but with Hyundai dealers I still don't trust they will do what they say, too many people don't give a crap and will do it wrong and say they will do it to appease you. Call me cynical.
So my experience at the dealership was actually pleasant. I dealt with a different service advisor and they were very helpful and even gave me a discount on the oil change. They even had a box of the Quaker state synthetic 5-30 sitting behind the counter specifically pulled for my oil change.
Also this employee had the right info and said since mine is a turbo the recommended oil change is every 6K and that the non turbo is 7500 so obviously who I spoke with before didn’t know anything about their own vehicles which isn’t cool.
I am so glad I decided to do this first early oil change and not wait until the recommend complimentary one. My car instantly felt smoother , pulled harder and reinforced my love for this platform. I know it’s not just in my head too, getting that factory break in oil out of there is crucial if you car about your engine and performance in my opinion.
They even gave me the left over oil, kudos to this dealership (this is also where I bought the vehicle) . Now hopefully they give me a good trade in value when I buy my Kona N in a couple years 😎
Yeah I will most likely be back at 7K for my complimentary maintenance plan since I just did one at 2K. And then I’ll just go at 5K intervals until the program expires.
I run premium fuel so I hope that helps a bit with the carbon buildup and fuel dilution. I’m no mechanic or gear head but I want to do everything I can to take care of the car and keep it running at it’s optimum level. This is my first brand new car and I have always wanted one so I could take care of it properly from the jump. I realize for longevity I probably should of gone with an NA engine but the turbo and DCT was just so much more enjoyable.
Yes , I should probably create a signature with my model.
It’s a 2021 Limited AWD Thunder Grey . Also I heard some peoples engines or parts are made in China . I checked all mine out and it’s all from Korea.
Yep i have seen your posts about the rear diff and I will be having that fluid swapped out sooner then later. I am a spirited driver , I’m not always stepping on it but I do enjoy performance.
What mileage do you recommend I change out the rear diff fluid? Was it 7500 ?
Thanks for all the help!
