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.

Seriously doubt it, although a good synth may hold viscosity better
at high temperatures and load. Also seems [judging purely from
the notoriously inaccurate guage] to hold pressure as well in
desert temps. And I *still* change at 3000.

Not sure that's fair, since I've seen a Toyota engine run out of
oil [loose filter] to the point it stopped... and then after a
good dose of STP and Marvel mixture, run for another dozen years.
Don't think I'll try this on my own engine, thanks.

sorta what i was thinking. i know dino is good enough for a couple hundred
thousand miles anyway (if changed ever 3k) and personally i dont want to be
driving a daily driver with that much mileage anyway. the toyota i
mentioned earlier was used commercially, even towed 12,000 pounds
occassionally.

never had a problem with the lower octanes. run the cheap stuff - you can spend more
on mod's that way. =)

also, if you off road, especially in dusty conditions, change the oil and check the
air filter more frequently.

I dont think Toyota is a fair comparison. I have seen the abuse they can take and
still keep running - like running until there is almost no oil, and then filling it
up and starting it up and driving it again.

I agree. If Jeeps were built like Toyotas, there would be no reason for
ANYONE to buy anything else. Ok, well there is Porsche...
