Hey Everyone,
I just took my Sonata to the dealer to complete an engine recall. They needed to test the engine for knock and other issues since they claim a certain amount of engines from the 2011-2014 Sonata model years are defective. I'll provide a link below which has more detail on the problem. Basically their fix it to install a shorter dip stick which increase the oil sump capacity from 5.0 to 5.2 quarts. In my opinion it's a terrible fix because it doesn't guarantee anything, only increases oil pressure. But the issue is I always use M1 or Castrol 0W-40, the service manager said they need to top off the engine using 5W-30 synthetic blend as per Hyundai Corporate. Will adding .2 quarts (189ml) of 5W-30 synth blend cause any issues? I'm 1000 miles into my OCI, don't want to dump the oil unless I really need to.
For the record my engine has never consumed 0W-40 of 5W-40 which is why I use those grades. I didn't have the same luck with 5W-30 which required top off after 2-3 months. I suspect the turbo variant engines like higher weight oils, but maybe that's only true for my engine.
Either way, the only reason why I took my car to get checked out, is to keep the warranty intact. Which is now extended to 120k miles due to potential engine issues.
