I advised that both, my manual and the dealerships I frequent make no mention of this. The dealerships abide by the manual. I've owned two Sonatas and now a Sportage with the 2.4L without issue and our 2.0T now has 179k miles without issue. So your last "dig" at the 2.4L is cute but not my or my family's experience. I've also used 5w20, 0w20, 5w30 and 10w30 in the 2.4. Oil choice was not my contention your claim that Hyundai specifies 4k mile oci was. Now you cleared it up by saying "your dealership" does this [not that it's a mandate from Hyundai]. So that settles it for me.
All in all, thanks for your points of view. All are welcome regardless of disagreements.
What interval are you running then? 7500? You're going to get sludge unless you're using synthetic. Any time i see a car that's consistently run 6-7000 between changes it has sludge or is very dirty
Yes, I use synthetic in my current 2.4 Sportage. Since I DIY, it gets changed between 4-5k miles now that I've reached 12k on the odo and my non-scientific break-in schedule is done. The Sonatas each had maint pkgs that called for every 6k mile intervals. Those vehicles got Synthetic 90% of the time since I brought my own to the dealership. But that oci was the dealership recommendation. When I pointed out the manual says up to 7500, they said that would be fine too. After doing the math, I realized that the only I'd get the full value of the pkg would be to change out every 5k miles because of the mileage per year calculated by pkg exp date. So that's what I did. When the pkgs expired, I did a few dealer changes before going DIY. When the Techs would wrap up the change, they would ask me what interval I'd like the computer set to...with 7500 being the max. I kept it at between 4-6k miles. The Santa Fe Sport Turbo is the wife's vehicle. She drives under the Severe Service Schedule (works 5 miles away but takes 35 min or more to get there). Every Tech I've talked to ( including bitog member, 69Torino), and the Hyundai USA tech help line have advised that as long as the max oci in manual is met, along with proper fluids, warranty coverage assured. Just don't extend past 7500.
