Re: uphill, with a/c, high altitude, & a trailer: use premium gas?
I do use premium, like Jerry suggested to climb the mountains out
of California, because I ping normally on hard acceleration at sea
level, and can't stand to let a Japanese car pass me. That means drive
about ten miles an hour faster than on the coast, at eighty five.

Re: uphill, with a/c, high altitude, & a trailer: use premium gas?
Actually, as you go up in altitude you can usually get by with a lower
octane. Thinner air means lower psi in the cylinder which is a lower
effective compression ratio. In Colorado it's common to find 85 octane
gas in the mountains. I don't reccomend it and neither does the owner's
manual but it doesn't ping when you rattle around at 8000 feet and up.

Of course driving on level ground at higher altitudes allows a lower octane
to be used. Driving uphill from lower altitudes doesn't give that same
ability.
