weirdest thing....my low oil light came on tonight and it will not go off....I checked the oil and the dipstick reads full and the oil pressure is fine, right where it normally is on the gauge...the only thing I can think of is that the temperature has just fallen from 60s-70s everyday to 40s-50s...I don't know what to think....is the car safe to drive....on a really tight budget right now and would prefer not to change the oil right away unless I have to seeing as how I am about to have to spend big money this weekend....what do you all think?
