Just what does this prove? Where is the link between a clean intake tract and the severity of use of an engine. If someone knows of one, please show me study data. How is it "crucial" to not drive like a granny? I had a 1997 Taurus that was my dads; he "grannied" it badly, yet the valve train was very clean after 100k miles when I popped off the valve covers. My wife's former 1996 Villager with 240k miles on it had a clean valve train, despite my years of "cheap" (inexpensive) house brand oils and typical filters, even with greatly extended OCIs.
Some engines have a tendency to sludge up, most don't. Some folks neglect their maintenance routines, most don't.
I see no correlation, let alone any causation, in regard to how one does or does not "granny drive" their vehicle and a clean intake tract.
Thank you for that tidbit of information.
