Interesting, thanks for the link. I noticed in the owner's manual it was recommending top tier gas or fuel additive packets or something. Got it on my list to look into. Looks like top tier puts more gunk on cylinder heads, but WAY less on valves.

Do you have a source for the additional buildup on the cylinders? Only things I’ve read mention a 20% reduction in build up on the valves but nothing about any additional buildup.

Figure 8 in the PDF. It's not much, certainly not compared to the amount of reduction that you get on the valves.
