Yeah, I've wondered about that. The thing is I actually do run fairly high loads during my pulses in P&G. Of course, that's followed by my glide at idle. And even though the pulse should lead to some fairly high temps, it's for a fairly short period of time. So...I don't really know
You're probably right that it would be worth it to "burn it out" every so often. I know soot build up can be a problem with the VG mechanism, as well as other things. Occasionally (once a month or so) I do have to make a trip out on the interstate at 60-65 mph, but even that won't really push my engine at all when I'm unloaded and in 6th gear.
