I was seriously torn between driving in lower gears (higher rpm's) to warm up the oil on cold mornings, or driving in higher gears (lower the rpm's) to protect my engine seeing that my oil is cold...! I couldn't decide what it is that I needed or wanted to protect more..?? (I know, I tend to over-analyze, I know...that is the curse of being an engineer)!
Anyway, I finally decided to park the Z in the Garage and drive the Titan daily back and forth for the seven miles to where I park from now till the weather warms up again - and then maybe. I think I'll keep my baby for weekends and fun drives or whenever I just can't take it anymore and just HAVE to drive her.... I wonder if I can make it a couple of days even...!!!

Paul,
"Cooler" oil as in, normal operating temps... as in temperatures that are below 240-250*F. Obviously COLD oil isn't good, but generally speaking oil that is 200-220*F offers better protection compared to oil that is 30*f hotter.
Now it's all also relative to WHAT type of oil you use... so it is a little more complicated.
