Hi Jim,
So is there any real-world way for LMM owners to overcome the cylinder wash problem?
In the Midwest, B-20 seems to be becoming more prevalent -- politics of the corn belt, you know. Although I have a local source for the pure stuff, when I'm traveling elsewhere in the region it's sometimes a pain to have to hunt for it, particularly if I don't pay attention and let the tank get a little too low.
Would adding extra lubricant of some type moderate the washing issue until I reached a station with B-5 or pure dino?
And of course the ever-popular question about why GM designed an engine this way when the government was steering things toward increased use of these fuel blends? Much as I've loved my GC trucks over the years, I continue to be amazed and disappointed in some of their engineering and design decisions. Oh well...
