in terms of oil pressure?
 
My car usually runs around 38 psi of oil pressure when the engine is warmed  
up. The last couple of days its been down closer to 30 psi. These numbers are  
while cruising at 3000 RPM. The temps here have been pretty warm, around 95  
degrees. As I'm getting the car ready for the trip to Iowa, I'm getting more 
and  more concerned about everything.
