i got a major over heating problem today, i had juss noticed it today when i was letting my car warm up and then i went back to turn off the car because i wasnt ready to leave yet, and seen that the temp had went to 3/4 of the stock temp gauge? i had poped my hood and checked for oil and radiator fluid. there was NO oil and yes there was radiator fluid. in the 2 and a half years ive never had oil that low because ive always check it. any ways i went to kragen to get some oil and it took 2.50 qts to fill it again. started to drive and when i got stuck at a red light, the temp started to raise again, but then i take off and it goes back down. i dont know what is wrong with my car, can someone tell me or tell me what to check.... thanx

time to change your thermostat maybe??idk sounds a bit fishy did you lose oil again after you had put some more?? any leaks in the engine bay???have you checked you hoses and you water pump?
