High Detergents/TBN for shorter oci's

[SubieRubyRoo]

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.

I'm always finding some discrepancy or overlap when it comes to this subject. I guess that's why some, especially Mobil, emphasize carefully "balanced" oil.

This was from Amsoil's recent blog. I know what detergents and dispersants do, but I didn't think they help in the piston ring area.

Since I purchased HPL oil and I plan on keeping reasonable 5,000 miles oci 's, I wondered if there is any advantage to the high Detergents/TBN levels of this oil in a oci of this length?
Any possible disadvantages of going on the high side when not really necessary?

The HPL will most certainly go longer than that, safely. Why not do a UOA at 5k and go from there?
