so leaving school this afternoon car woudn't start. it was 40 degrees out, raining. im also running 20W-50 oil. engine turned over and turned over. nothing... i was turning it over in like 10s intervals with a few seconds between each. finally battery started dying so i stopped. i txtd a few friends to see if anyone had jumper cables. while waiting for a response i tried one more time. car tried to start, then i tried again and it started. some other stuff, after it started oil light came on and oil presure was at 5. this was all at idle. after maybe ten minutes of driving, looked like oil pressure dropped a little so i pushed in the clutch to see if it would drop down to idle pressure and sure enough it did. havnt had any problems since. any ideas as to why it wasnt starting earier??
