Great explanation Frank!
I wonder what extra precautions, if any, are required to make engines with cylinder deactivation reliable? With the same cylinders deactivating and shifting a higher load to the remaining ones, I would expect those to wear out faster. Is there any evidence of the active cylinders wearing out at faster rates than the others?
I bring this up because I get a full Blackstone oil report every year when I change the oil on my TSX. Every year it shows slightly higher than average iron wear, suggesting I might be wearing my engine out a little faster than most. My best guess as to why this would happen is that I tend to shift early and place a larger load on the motor when accelerating. I'll go to 85-90% load on every acceleration event including infrequent pulse and gliding.
