But if I let the oil temp begin to register on the stock gauge before i begin driving, then it finishs warm up rather quickly as i drive it nice.

I've noticed this too. Funny thing but logical. I always give it 10 to do it's business.

It probably isn't necessary to wait for the oil temps to rise for normal street driving. The Ester oil, or any good synthetic 5W-30 flows well at fairly low temps. 5W refers to winter viscosity for a multi-viscosity oil. According to ehow.com, 5 weight oil will pour properly at -40 deg. F. That means you will get good enough lubrication for road use in most places. The 30 refers to viscosity at 212 deg F (100 deg C).

I can tell you that oil pressures run near 100psi at 2k rpm when the oil is cold. Once the oil hits about 180F, the pressures drop to about 60psi at 2k rpm. Also, removing oil with my oil extractor is much slower with cold (more viscous) oil than when it's up to temp. Both observations are enough to make me take it easy until the oil heats up. However, i can't really comment on any detrimental effects of not doing so.
