The best is good oil that flows in the cold like synthetic, a filter
that is not old and clogged up and just driving easy for a few
minutes. For highway speed a few minutes till its warmed a bit is best
but just take it real easy while the oil is hardly lubricating in
frigid temps. Ive gone to 0-30 mobil 1.

Thanks for the reply. After reading this post I have started
monitoring the intitial rpm at startup at my Camry 2005 (4 cyl). I
see similar behaviour as described here. It start ~1,600 rpm and goes
to ~800 after a while. When I switch to drive when at 1,600 rpm, it
drops from ~1,600 to ~1,000 rpm. My car has ~100,000 Kms (63,000
miles). I do not see any issues when driving. Any comments or advise?
