dumb question.

This is what I get for dropping my Jeep off at a Dodge dealership for
a quick/cheap oil change. Oh well, worst off I run for a while,
flush, and refill. Only $19 for a full oil flush isn't bad.

By the receipt it looks like they put 5 quarts of 5W30 in.
...er..
Should be 6 quarts of 10W30.

I gotta start paying more attention....

Oil looks nice and clean but 5W is more for < freezing expected
in the next interval. It's close to fall, but not that close to
winter. On the other hand the oil is only 10 cold with a viscosity
of 30 at operating temperature. i.e. more for easier starts in cold
weather.

I'll top off the oil with some 10W30 synthetic so that's not a biggie.

Still though, I've got a few more thousand miles of travel in 90+ weather.
From what I understand there really isn't an issue since the weight is still
30 and the engine operates at the same temperature anyway.

Thoughts?

Why not try a can of STP?

I try not to put additives in the oil. Figure the
bottles have enough as it is.

From what I've read (and I've read a lot in the
past hour or so) it seems that 5W30 is the standard
oil that all Dodge dealers install and is more for
the modern engine with tighter clearances. Since
my 4.0 doesn't burn any oil or drip even with synthetic
it should be fine for the next 3,000 miles.

Worst off I get an excuse to drop in a nice shiny stroker kit.

My owner's manual (1995 YJ) says to "Select oil viscosity according to the
lowest air temperature expected before the next oil change using the engine
oil viscosity chart". According to the chart, 5W30 is good up to a "lowest
air temperature expected" of 60º, and 10W30 is good down to 0º! There is
considerable overlap there. According to this information, I could probably
get away with either 5W30 or 10W30 year round, living where I live.

It's not just easier starts. An oil that is too heavy can cause increased
wear during cold starts, because it doesn't get to the bearings fast enough.

Like you, I would probably have chosen 10W30 for an oil change in August,
but this little misunderstanding won't hurt anything.

I put a couple of hard-drive magnets on the oil filter. Figure it
won't hurt anthing and if it picks up some metal that's good too.

That's my feeling. Maby they will send me up to Peterson AFB this winter.

Still not needed, Doug. COS hasn't seen more than 2 days below zero
in a long time and AIR the coldest we saw this last winter was like
-5. This global warming thing is questionable in it's extreme
application, but we haven't had much winter for a good 8-10 years. Of
course, the decade following the last string like that made brass
monkies an endangered species <g>.

Ok, this is also OT, but serious-what is a "brass monkey", if anyone
knows (they very well may not)? It appears to be an old (circa
1890's-early 1900's) railroad term, but all efforts of historians to
find out have been so fruitless that no one can even speculate as to
what it was. I find the origins of old terms in our language
interesting, so I would love to know if ANYONE in here has any idea.

The best explanation I have heard dates to the old navy times. They used
a formed/dimpled brass plate on the old ships to stack cannon balls
on, the brass monkey. When it got cold enough the brass would shrink and
the cannon balls would roll off. "Freeze the balls off a brass monkey"

Of course this raises a new question. Why did they call it a brass monkey?
