Lets see.... if, not, no, well no
yes knock sensor not. Or in other words, if your engine DOES
have a knock sensor, it may benefit more from the higher octane
than an engine without one.... IF [which is pretty rare] it was
actually dropping engine performance due to sensed knock.

A knock sensor results in modified ignition and mix... IF there
is knocking, which surprisingly doesn't happen.

I get different mileages per tankful simply by buying gas in
one area versus another. Pretty consistent, and it is the
same brand, just different geographical area.

Besides, I *did* say anecdotes from credible sources.....

Or in other words, "maybe".

Synthetic oil, yes. It holds up better during heavy use.
Premium gasoline? Haven't heard of that one. My 90 and my 98 were both
designed to run on 87 and do that just fine on and off the road.

Depends on how long you want to keep it.

is it even possible to break down premium (valvoline/castrol) dino in 3000
miles or less?

ive gotten over 400,000 _hard_ miles out of one engine that was dino oil'd
every 3000 miles. granted it was a toyota 4 cylinder but still, even a
toyota requires lubrication.

Use the lowest octane that doesn't result in engine ping. Anything more is
money out the tailpipe.

I'm not a fan of synthetic oil in jeeps, unless its been run with synthetics
since the first oil change. Switching to synthetics on a vehicle with a few
miles may result in maddening leaks that you didn't have before. Also, its
hard to justify the increased cost, especially since offroad use introduces
dust and other contaminants that aren't issues on street cars, and which will
require you to change oil more often than the extended frequencies touted by
the synthetic manufacturers. My advice is to stick with dino oil, and change
it every 3,000 miles.
