this car has about 70 lbs @ startup and comes down to about 15-20 after its warm. and it comes up w/ rpm like it should but--after driving awhile or making a pass it around 5-10 and will stay that way until it cools down completely---any one seen this before-the motor is pretty fresh in this one and it runs great---it was running with royal purple 10-30 when it ogt here....
 
just like syrup in july , viscosity of oil changes with temperature,


its not bleeding off just thinning out due to increased temperature and helps it to to reach the engine parts.


if your coolant temp rose higher than normal after a run than that might explain the lower oil pressure
if it returned to normal of about 15-20 at normal op temp (cooled down) than i dont see a problem
