i just got my first oil change at 5000 and changed it to synthetic. which was 4 days ago. All of the sudden i was driving my car today and the oil light started flashing with an alarm going off for about 10 sec. then it went off with the light still flashing. oil temp was fine.i pulled over shut the car off and then back on and the light has not came on since. I chk eng oil temp and it was normal. what the heck went wrong. has anyone else ever had this problem??? was it just a short???
