Dino in hot, efficient running engines results in varnish, and consumption.

This is what the cylinder head of my old Honda looked like when I was commuting almost 800 miles a week. ( 1250 kms+ ) I changed the engine oil about every 3 weeks, and I bought oil by the 4x4 case.
I had it apart to change the timing belt, and do a few other maintenance items.
When I had it apart previously to change the valve cover gasket, it was clean enough to eat off of it.
my d15b7 looked just like that when I got it. changed to mobil1 and wix filter and a little seafoam added to the oil and its now much cleaner at about 2500k after the change.
