Re: dumb question.
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.
Gene Berg said that "the heavier the oil, the less it lubricates"
http://www.geneberg.com/article.php?ArticleID=237 third paragraph. Ignore
the part about clamping a cow magnet to the outside of your oil pickup tube.
;^)
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. :)

Re: dumb question.
It doesn't matter. You're still getting the protection of 30 weight oil
at normal summer temperatures, within the design life of the oil. For
more than you probably want to know about motor oil ratings, see:
<URL:http://www.advanceautoparts.com/english/youcan/html/ccr/ccr20040601ov.html>
And $19 is a good price. I last paid $30 at the local qwik lube.
But they put in enough to bring it up to the "full" mark on the
dipstick, too.
Here's one, though: The guy at the lube shop claimed that the red dye
in ATF fluid is designed to give up and turn brown about the same time
as the additives in the fluid give up. Anyone know if that's true?

Re: dumb question.
It doesn't matter. You're still getting the protection of 30 weight oil
at normal summer temperatures, within the design life of the oil. For
more than you probably want to know about motor oil ratings, see:

And $19 is a good price. I last paid $30 at the local qwik lube.
But they put in enough to bring it up to the "full" mark on the
dipstick, too.
Here's one, though: The guy at the lube shop claimed that the red dye
in ATF fluid is designed to give up and turn brown about the same time
as the additives in the fluid give up. Anyone know if that's true?
