I think that's what happened to me, just sent out the sample to Blackstone (PUE 5W-40), I went the maximum 5K allowed by the manual. I've been doing a lot of bumper to bumper driving recently, I think fuel might diluted the oil somewhat.
The oil was pitch black coming out but it flowed well. When I wiped the container I could see the oil wasn't completely black. I can't wait to get the results, although I'm worried they might not be good.
Hyundai pretty much discontinued this engine, the new Sonata now has a smaller turbo that makes less power, they no longer offer the engine found in my car on the Santa Fe and Genesis coupe. Recently I've also seen a few of engine failure posts on the Sonata turbo forms. Who knows how these owners took care of their cars, I think some people don't follow the OM and do extended drains. I recall one member trying 15K OCIs...
You'll be fine. The engine was discontinued in the Genesis Coupe (Santa Fe Sport will remain unchanged) because they want to make it more 'upscale', according to The Korean Car Blog. All forums will bring out the 'worse case scenarios' as well. The oil color doesnt bother me at all anymore. I change out at 4K miles and have never smelled fuel. I even used a dexos synthetic blend once, and after 3500 miles, no fuel smell. I have seen enough UOAs where wear numbers have been fine with some dilution involved. Now, 15k miles is just asking for trouble.
