we just had a real cold spell where i live and the other day it was minus 15 degrees. i started my car and let it warm up for 20 minutes. to melt all the ice on the windows and get the heat going. anyway, about halfway home from work i noticed the oil warning light was on. so i get home call my dealer and make an appointment to get it checked out. that was the other day. today its not nearly as cold and when i started up my car the oil warning light came on then went out like its supposed to. has anyone else experienced this when its really cold, below minus 10.
