Obviously, that's not a consideration here. I'd shoot for a temp somewhere around 200º-220º F.
My commute to work is short, too (8 miles, 20 minutes). I see cylinder head temps near 250º F in similar ambient temps. I wonder what my oil's temp is? Of course, you could go with a thinner oil, too. That wouldn't help with operating temps but it would provide some peace of mind knowing that the oil is circulating on those cold starts.
I'm not sure what your talking about, so i assume I have to older vapor. It came with 1 probe for the spark plug, which I bored out a little and use for the top oil bolt. I usually get around 180*F on the highway in the summer, with around town highs in the 220*F range.
