as a side note...I'm planning on dealers doing all oil changes so if "somthing" happens, oil maintenance is not an issue.
* I know some will post saying "as long as You do it at proper intervals,use approved oil, log it and save money. I'd rather pay a dealer and leave NO questions about that particular maintenance.

Thanks for all the replys. I guess I will mention the oil pressure to the mechanic next time I am at the dealer. I wonder how low the oil pressure has to be to trigger the warning light? I am not going to let it bother me. My voltmeter gauge definitely is either way above 14 volts or way below but that doesnt bother me because my 07 did that and never gave me any trouble. I guess this truck is just different than my previous truck. Thanks again for all the great replys.
In the old days, 10 to 14 psi would turn the light on (dodge was 14, ford was 10, did not work at GM dealer). General rule of thumb in a racing engine though is 10 pounds per 1000 rpm.

I'm used to driving old Ford trucks, and on those, it seems like the gages always read the same numbers if it's running, unless something is wrong.
Ford's gauges (and many other manufacturers) don't move because they don't give you the actual reading. They stay in the middle to make you feel good. It's not until something is way out of line that they then rapidly move one way or another.
GM's gauges on the other hand tend to show a more realistic reading that varies with engine speed and temperature.
