My experience is that you can definitely use a lower octane grade at
altitude without the valves clattering. Once you ge to Jellystone the
altitude is near 7,000 ft and unless you've got it under a heavy load,
save yourself some $$ and give the regular a try.
You might CYA and take a small bottle of octane booster along in case
you ge bad gas or it isn't happy with the chance.
