High Detergents/TBN for shorter oci's

Sufficient viscosity and frequent changes are the key to Hyundai and Kia engine longevity. No oil is going to prevent fuel dilution and hard abrasive carbon soot from wearing you engine, but getting that crud out by changing the oil will.

So HKs are the only engine that suffers fuel dilution and combustion soot? Interesting. One would think HK would have copied a more successful engine instead.

Nope, many GDI/TGDI engines have this problem, HK takes it to another level and their engines are more likely to catastrophically fail if you aren't on top of it.
