just a dumb quick question:

Yesterday I changed the oil and oil filter in my mom's '95 ZJ V8. I put 5 quarts of oil in the engine and the dipstick shows that it is full, but not too full. THe oil pressure gauge, however, shows at about 70. This seems to be too high. Is this something that I should worry about? If so, any ideas what the problem could be? Before the oil change, the pressure was around 40.

Thanks for any help!
