uphill, with a/c, high altitude, & a trailer: use premium gas?
 

..... in my 4.0L TJ?

Manual says use 87 octane and that's just great. Should I up the octane any as
I head up to 6K feet with my family, a camping trailer, the A/C blowin', etc?

Temporarily upping the octane for climbing mountains/hills wouldn't be a bad
idea at all... it'l help reduce the pinging that can happen when the engine
is under load at altitude. Run 87 the rest of the time though since higher
octane doesn't really do anything for normal driving in a 4.0L Jeep engine.

Hi Jeff,
There is less air at higher altitudes, therefore less octane and
gasoline are needed to maintain the fifteen to one ratio. Of course,
less energy used equals less horse power.

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.
