While I’ll agree they probably did design some in as any manufacturer does that uses a mm, that doesn’t account for the well know dilution problem with these cars as if it did, they wouldn’t be trying to fix it.Actually, the engineers do. The MM ticks away 2-3x as fast under shorter trips and frequent cold starts. Longer trips and prolonged operation under lean burn (hwy cruising) extend the intervals a bit longer. And all of our available readouts confirm that the MM operates a tad on the conservative side:

There's nothing wrong with changing out early. But as several members have proved, 5K may not always be soon enough.
