10K miles is waaaay too long for an oil change...especially with high miles IMO.....from what I've read before these are the minimum oil pressuse readings:
6.0 psig at 1,000 engine rpm
18.0 psig at 2,000 engine rpm
24.0 psig at 4,000 enigne rpm
If when you are driving the pressure goes within these specs I wouldn't worry about driving it home and change the oil ASAP.
Also I wouldn't put too much faith in the stock oil pressure gauge....the sender and or gauge could be going bad. If you truly had no oil pressure you would hear your lifters making noise, etc.
Good luck !
