Since I have had the bearing issues, and have listened to some other
opinions on the subject, I now use 10w-30 oil. I added a quart yesterday,
when it was around 15 degrees or so. Yeah, the oil is a little thicker when
cold,, but the oil pump will still pump it, and I'm sure it hangs in the
bearings a bit better.

Remember that the thin oil (0w, 5w) was developed primarily for better fuel
economy. It is also better for producing HP as has been proven on a dyno.
Nothing wrong with it, but IMHO in modern high-volume, low-pressure oil
systems, 10w-30 seems like a better way to go on older engines in normal
temps (down to zero, with maybe colder temps overnight). If I lived in
northern Minnesota (this is hypothetical.....I would NEVER live there!!),
thinner oil would be better for the subzero temps they see during the day.

Hey, hey, hey!

Don't shoot the messenger.  I'm just trying to explain where people get
the ideas for using 10W-30.  Not endorsing the idea at all.

I just checked 2 owners manuals, the one for my wife's Rodeo and the one
for my sister's Civic.  Both indicate that 10W-30 is acceptable down to
0 degrees F.  I don't have a SHO manual to check.

Later, and thanks for the flame.  Luckily I had my fireman's hat on.
