In 1994 I started a Chevy S10 2.8 at -22 degrees with Pennzoil 10W-30. Ran fine after a few seconds. What stopped me was when I pushed the clutch pedal, it did come back up. Took about a 15 minute warmup before I could work the clutch pedal.
Lowest temperature for 10W30 oil

For me I wouldn't want to go much below -10F with it. Will it work? Sure. Are there better choices for colder temps? Absolutely!
Thanks for all the information guys. I appreciate the quick responses.
I usually use 5W30 year-round, but this fall switched to 10W30 due to oil usage. I wanted to see if switching to 10W30 helped with excess oil usage (no noticeable difference).
My car manual (1994 Honda Accord) recommends 10W30 only when temperatures are greater than -3 C (26 F).
I just needed some peace of mind, and from the comments here, 10W30 should be fine. I will switch to 5W30 in the next two weeks. BTW. Battery is one year old and cranks fine.

Ummm, -40F = -40C.

Heck, up until just a few years ago, I always used 10w30 in the winter and 10w40 in the summer. It'll be just fine.

They do? The 2 cars I have don't make any noise after cold start up. And two different 3800s my buddys run that don't make any cold start up. My past 3800 and 3300 didn't make any cold start up noise.
To the OP: I used 10w30 dino all year before on previous cars. You shouldn't have a problem.
