Fuel dilution is only an issue if the engine never reached operating temp, ie short trip winter driving. My engine runs for 8-10 hours straight and the oil has never smelled like fuel. The 1.6l NA gamma engine is pretty solid. The accent is kinda like the old 90s corollas. Very reliable cars and probably the best car that hyundai makes.
Would M1 EP stand up to 7500 miles of severe service?

Why would I be on borrowed time? It's not a theta engine.
There you go, I have a 1.6T Gamma. Operating temperature reach may be the the case for you, but I reach temperature and I would get some fuel dilution even in the summer. That fuel dilution was greatly and I mean greatly reduced this winter. And unlike before with another oil, this oil flashed off all the increase level of fuel in the oil this spring.

Oh really? So, what are you doing...Uber or Lyft around Boston? I can’t imagine a worse place to do it, haha. You must be at Logan all the time. That place is an absolute zoo. I try to fly out of Manchester whenever I can now, it’s so much easier...no lines, easy parking, no in or out traffic.
You should do a documentary on YouTube about your car/your maintenance. Because if it can handle what you’re putting through, people will want to know about it. I’m actually kind of serious. Lol. People would be interested.
I'm sure these mechanics would be happy to perform the more frequent oil changes as well. How long has Toyota been doing 10K mile OCI? Two decades?

I have a friend that was an engineer for Hyundai. He said he’d go into his Monday morning meetings with a suggestion on how to fix a simple problem - whether that be a knob on a radio that kept breaking or a sun visor that kept falling down - he said he, or anyone that came up with a solution would be laughed out of the room. Even if it costs 2 cents, it’s too much. They wouldn’t do it. They won’t spend to fix anything unless they have to or are forced to.
And they aren’t the only companies he’s worked for that are like that. He’s seen other companies buy a transmission from a reputable manufacturer...they present them with the tranny. And said car company says...ok, no, we don’t want to pay that, so reduce the component quality and rip the price down. And they will. Meanwhile a different car manufacturer will buy the same exact tranny and keep the quality/price as is, and it lasts twice as long.
All of these companies could be build super reliable cars if they wanted to, some don’t. It doesn’t fit their business model. And I’ll tell you what, if you look at it from their side of things...it works. It’s a business. Most people won’t even own that car more than 10,000 miles or so past warranty. Then they’ll buy another one or lease another. I have a friend that has never had to fix one single thing on his Hyundai’s - he’s never owned them past 50,000 miles - and he loves them! Buys Genesis almost exclusively now. Different strokes for different folks.
And I probably should mention that I do like Hyundai cars/SUV’s. I have seen some go pretty long on Mileage without a ton of problems. I’d call them at least average in reliability.

Keep in mind a few things...mechanics actually enjoy giving people GOOD advice on car maintenance. They really do. And mechanics hate performing oil changes on customers cars. You don’t make money on oil changes. It’s a waste of time. You go out there and get that car, drive it in your bay, change the oil and get payed .3 tenths of an hour. Meanwhile it took you 20 minutes to find the car in the parking lot and drive it in. Or the place they work for is running a “promotion” and you have to give them a free tire rotation with the thought that we’ll “sell more brake jobs”! To only see them take it somewhere else. Heck, most places have lube techs on salary...believe me they don’t want to see more oil changes come in and work harder. Lol.
I work in the industry. I go 5,000-6,000 miles on oil change intervals. And believe me when I say this, MOST techs I know go 3,000 miles. They think I’m nuts for going even 5,000 miles. They joke when they’re pulling their 3,000 mile oil and ask me if I want it.
But I’m not suggesting oil change intervals for people, I could care less. All I’m saying is...mechanics aren’t telling people to shorten up their oil change intervals to make money.
So , looks like you have a Hyundai Accent with the 1.6L Smart Stream engine ... I do not know if this engine is DI or not as Hyundai shows DI with multi port PFI indirect injection listed . I only run a 4K mile OCI with a Hyundai 2.4L DI engine - all I can say is try it for a 7,500 mile OCI then get the oil tested to know for sure .
*Owner of 2.4L Hyundai '17 Sonata 36K miles (with limp mode software upgrade) . After factory fill I run 5W30 D1 / G2 synthetic oil (various) and either the OEM oil filter -35505) or the Fram Ultra (9688) for 4,000 mile OCI's . I keep oil at the "F" mark on the dip stick and I keep receipts ... Probably won't matter much but that is my routine I use with oil and oil changes . Wife's 3.8L Kia (2007) and daughter's 2.0L Hyundai (2010) engines have been boringly totally reliable with my oil and oil change regiment .
Because typically, IMO, Hyundai engines are just not made as well in design and they use lesser quality metals and materials than say Toyota, Honda, Mazda, etc. They are 100-150k engines. Not saying they'll blow up, but they'll start having oil burning problems, gasket/seal problems, etc., etc. At least that has been my experience with them. Yours may turn out to be the exception. I've generally found this site pretty accurate: https://www.motorreviewer.com/engine.php?engine_id=17

I can't believe the 125-150k life expectancy assigned to these engines. Would not work for me. Every car I have had I put 230-300k on and even then, the engines were fine. Sold for other reasons.
The Toyota 10K OCI is for normal driving conditions. If you driving highway, you can even do 15K probably.
The severe service, is a different story, and if you want to keep your car for long time, even on Toyota 10K is way too long for severe service.
The other things to consider is mechanics see the vehivled with problems. Other than preventative maintenance items, if they see it then, they basically don’t see the cars or even talk about what could be a problem. Mechanics will see a sludging engine, but not realize they are only f5% of all those vehicles had that problem.
So mechanics will only see those Toyota’s that operated under severe service and think all then should be service under the severe service schedule.

On the flip side they are also NOT seeing these problems with the vehicles on the shorter oil change intervals, but they are seeing them fail on the higher change intervals. Then they give their advice. Because they are the ones seeing it on a daily basis...seeing why it happens, seeing others not experiencing it...seeing the trends and correlations, will always lead a tech to say, "don't do that". It's the way it is.
It's like a stock broker telling you not to buy in a certain sector because he's seen people lose there (yet plenty do well in that sector). Or a doctor telling you not to eat high cholesterol/saturated fat foods because they can lead to heart attacks - because that's what he sees and that's the industry trend - yet others won't have heart attacks, many actually, or they'll be a new study saying cholesterol won't give you a heart attack (and five years later that's proven wrong). People in industry give advice off what they see, what they experience, what the trends are, what is happening now enough times to say...ok, there is something here with THIS. Same for guys who install widows, vinyl siding, hot water tanks, cook, clean, bake, paint, cut hair, grow plants, cut grass, sell watches, insurance. They're going to tell you what is best, a lot of times we won't take their advice and a lot of times it doesn't matter because we won't keep whatever it is long enough or use it to the extremes they consider "normal". And yet there are times we should have taken their advice (I've learned that too). Lol.
My engine uses no oil and runs just as good as when I bought it at 133k. I cannot see why it wouldn't go another 100k without problems.
Regarding the part of the statement that Hyundai uses lesser quality metals and materials, does the reviewer have proof of this or are they just spouting inflammatory poppycock?
Depends, dealerships seem to go with 10k for toyota/lexus. The real answer it
depends on operating conditions.
Test and find out. It’s worth the $20.
Pulling a trailer all day long or operating on dusty dirt roads would be what I would call severe service.
In There absolutely is a correlation between wear metas in uan argument in favor of using the cheapest oil that meets spec. So long as you maintain short intervals.
I can’t say it’s irrational, but it’s probably a minority opinion.
The logical compromise might be to use low buck synthetic for the severe service schedule.
There absolutely is a correlation between wear metals seen in UOAs and wear rates. Otherwise no one but oil change hobbyists would do them. And not for very llong.
