It sort of breaks my heart to start my Jeep up at elk camp every year... it's
usually somewhere around -15 F at 4:30 am when it's time to fire up the rigs to
get to the trailheads. I have a block heater but dammit, I can't find an
outlet to plug into up there <g>!

Would my engine be better protected if I switched it to synthetic oil before
the hunt? It's a '97 4.0L with 86K on it. Runs great. I'd probably switch
back at the next oil change. I typically do the oil every 3000-4000 miles. Is
it bad to switch like that?

In weather that cold, a synthetic is definitely a good idea since it really
does flow much better in extremely cold conditions. I'd run 5W-30 synthetic
in those conditions. Maybe even 0W-30 synthetic would be a good idea for
those cold starts. I don't run synthetic due to its added cost and in my
temperate climate, I don't see a whole lot of REAL benefit to synthetic over
a high quality mineral-based multi-weight oil. But I sure would run
synthetic without a second thought if I lived and drove in an extremely cold
climate like you do. :)

Synthetic is better at these temps but I wouldn't worry about 'only'
-15F, the Jeep will tolerate it easily. (different story around the -25
to -35F range!) Make sure you have fresh oil (5w-30). a good battery,
and get it to operating temp quickly (drive it, don't idle it for 20
minutes)

I'd be more concerned over the battery than the oil. For that temp and
that far from civilization, I'd replace any battery over 4 years old.

Can you please explain, why do you drive it to heat it up quickly?
Thanks in advance
