    Could be. Depends on the weight of the oil...the type or brand of the oil....the filter....the temp....I run 70lbs with Royal Purple Racing 41 in a 402 with a Lingenfelter oil pump and a 7 1/2 qt sump....post up with the specifics I outlined above and lets have some folks compare for you.

    oil brand is mobil one synthetic, at least thats what the guy told me...i just got the car this summer, so i dont know about the filter brand. The oil pressure starts at about 60 when you turn on the car then drops to about 55 when it warms up more. I am not sure about the wieght, but since the car is in upstate NY where its starting to get colder now, sould i switch it to a lighter wieght oil? and if i do nothing now what can be the reprocussions. The car is basically stock too.

    What weight is in there now? You should be running a 0-30/10-30 or 5-30 with a AC Delco filter.....I'd change oil and filter if I didnt know what was in there nor how long it had been in there....but your OP sounds within spec....

    At idle it should be in the 30's-40's...but at 2000rpm it should be in the 50's easy when warm

    I would change the oil and AutoRx that thing...get a clean start on life with your new car....follow the instructions...use dino oil during the cleaning and rinse phase....

    didnt want to start a new thread so....my pessure is as follows

    cold start 50-60psi
    operating temp 40psi
    cruise 40-45 psi
    high way 55-60psi

    i have noticed that after ive been driving for a while and i reach a stop, the pressure will fluctuate between 30-35psi. but as soon as i give it gas it it goes right back up to 40psi

    is it normal??

    That's pretty close to what mine does, rarely if ever, does it drop below 40 under any conditions. My in gear idle is set higher cause of my stall though, might be the difference.

    no, it only does it while im at a stop, and not all the time either.for example tonight i went to the gym and when i went to get back inthe car i turned it on let it sit for 10minutes i drove a mile and hit a light and the pressure went down to 30-35psi and went back up to 40psiwhen i gave it gas. went to a friends house for about 1hr , got back in my car turned it on drove the 5miles to my house. i hit 3 lights and not even once did it go below 40psi.
