Why for you is normal the fuel dilution on that engine?

Because it's direct injection, which is notorious for fuel dilution.

So, I just got the results of my OTHER 2013 Santa Fe 2.0T. This one has about 118K miles and had an engine replacement at 61k miles. These results are for only 2800 miles on the interval, vs roughly 3800 on the other car. This clearly shows that fuel dilution is still occurring, but notably less. The viscosity held up slightly better which makes sense due to the shorter OCI. Both cars have been on Amsoil 5w30 SS.
Aside from the idea of needing to go up in oil weight, the shorter interval clearly had an impact. As a reminder, the Severe OCI recommendation for this vehicle is 3k miles, so there's obviously something to it.

I don't know
With your fuel dilution problem, good chance your rings are jammed. Valvoline Clean and Restore should be your oil of choice for the next 5 oil changes. I ran Amsoil SS, Mobil 1 Extended, Mobil 1 ESP. I had massive fuel dilution issues especially in winter, Until I ran Redline Performance with it's high Ester content, my fuel dilution dropped to almost nothing to a very low amount. I was as high as 1.2 to 1.5 qts in a 3,750 oil change dump cycle. I am also tuned so I am dump more fuel then normal. BUT once the rings could move even with a tune I have so very little fuel dilution. My hypothesis after the fact was jammed rings. We now have Valvoline C&R that will do the job for $30 for 5 qts from Walmart. None of those other oils stopped my massive fuel dilution issues, so use an oil that CAN. My 2 cents.

Interesting. Thanks for sharing.
Re read, I think you missed an addition I put in as I hit edit send after you posted.
I'm trying to understand how Red Line helped with fuel dilution. Better piston ring seal?
Red Line won't clean up ring deposits.
I got a little stuck on that as well. The impression that Redline motor oil is mainly ester based is off base to start. Especially in 2024.
I checked not too long ago and the 2024 MSDS said 50-70% PAO. If I had to guess they're using 15-30% ester in some grades, which is a lot, but not majority.
I have the 2014 model of your Santa Fe in my family (son's car). I've maintained it since new.
Do you do the Hyundai-recommended Techron fuel system cleaner at every oil change interval? If not, this is a MUST for these engines. I don't always use the Techron, but I do use Gumout Complete Fuel System Cleaner instead--I believe this is roughly equivalent to the Techron product. Either will keep your fuel system in good shape.
As for oil, I think these Hyundai's (especially the turbo versions) are perfect candidates for Valvoline Restore & Protect oil. I intend to convert my Hyundai vehicles over to that as soon as I use up my older oil stash. Also, if your PCV hasn't been changed recently, I'd recommend doing that ASAP. Spark plugs?--If they haven't been changed in the last 30,000 miles, I'd recommend changing them ASAP. These engines don't require a lot of maintenance, but it has to be done on time. Good luck!

I do not think that Valvoline Clean and Restore has more cleaning power than Amsoil SS.
Sure it does, that's what that oil was designed for exclusively. In bet millions of dollars were invested into it. Redline has more cleaning power then Amsoil SS, that's what it took to fee up my rings. Amsoil SS did nothing for my car. I ran 4 straight runs of it in a row and I was loaded with fuel.
I have been running HPL EC to keep my rings free since Redline priced me out of their oil, and I have been running Motul 5w-40 8100 Clean Gen 2. That's nothing special, just a group 3 and will bind up my rings if I just used that. I had 2 oil changes left in my Redline Performance Euro 5w-30 I was saving. I just did an oil change last night so one more change out of Redline left. If I go to run a special oil in the future I will be running HPL instead of Redline since if I buy a 5 gallon pail it will be cheaper then Redline and HPL we all know is a better oil, especially when Redline pulled back some of the ester on the oil I used, on a formula refresh, if I remember right.
Impressive all the kinds of oils that you have been using and the data collected. Did you have think to add some good TCW3 in the gas to keep the combustion chamber clean?
Who said ANYTHING about % of ester??????? YOU did. Oxidation I think was 90, more ester then Amsoil SS at 49 in his Polaris Labs UOA. What is so so strange is Lake talked about esters cleaning ability what 2-3 sentences. AND CLEANING RING LANDS NO LESS.( with an ester based Restore for Cummings engines) And how the old Restores had 110 oxidation and it was ester that were the cleaners in that oil. Buster, of all people with truly a BS comment that ester doesn't clean ring lands. When clearly Lake's opinion is I would think high on this site. MAN what's up, are you on "gang up patrol"for the klan here? 123 here it comes ( we all know what I mean here).
I even PM Molakule on his thoughts why, the "Klan" of course was all over my posting on how "an oil stopped my fuel dilution". We have learned since how bad Hyundai/Kia jam up rings since they soot up their oil worse then other cars.
Good example 1.5 months ago a relative who owns a 2014 Kia Soul had it in the dealer with what appeared to be a fried engine from running it out of oil. It's his new driver daughters car. He changes oil every 5,000. Except this time he burned through it at 5,100ish. The software Hyundai/Kia used to push it into limp mode if it hears rod knock, limped it. She drove/limped it home and he towed it to the dealer. They said it was fried and offered him $300 for it. WHAT I said. VERY odd a dealer offers money. SO tell me more what's the job ticket say, he read the rod knock code # to me. I said you can always get rid of it for that . Take a gamble here, go get 4 qts of the cheapest oil you can find at walmart and fill it and drive it home. When you are buying that oil buy a jug of Valvoline C&R and a Fram Edurance oil filter. Run it 3,500 mile rinse and repeat 3 times. See if you get less oil use as you go. Check the oil every week. I have not talked to him since my last call, I will have to check.
Oh yeah. I asked him a week into this how the car is running he said like nothing every happen, no rod knock or weird noises.

No, it is not a combustion chamber issue. The car gets one of the 3, Redline, Royle Purple, or Amsoil injector cleaner every other to every oil change depending on my wallet weight at the time.
There are many different ester types and I'm not sure the POE Red Line uses cleans at all. It will run clean but to remove existing piston deposits requires a certain ester type or chemistry... and certain quantity. That was my point. I don't think Red Line is designed to clean piston rings. It does have high detergent levels so it will clean sludge and keep contaminants suspended.
So your not sure? So the POE Redline doesn't clean ring lands. Ok. It sure fixed my issue for some reason. Once my stash is gone I will be using HPL to clean. We all know that oil cleans and cleans very very well as per the HPL owner. And he also stated their HPL engine cleaner used ester to slowly clean. HPL uses the right ester to clean in their engine cleaner. We all now know the POE Redline uses doesn't clean "ring lands". I will use HPL now because Redline doesn't use the POE that cleans "ring lands". Glad you told me that. I don't want to spend good money on things that don't work or do the job they are suppose to do. 123 (cough)

Stay with the same oil and start using fuel injector cleaner with PEA.
