Oil is burning or leaking
I have a 74 mustang 2 4cylinder, I check the oil every morning and it seems to be low every time. So I fill it up to full and it stays full all day til the next morning... I dont know if its leaking or burning up, cause the car never over heats and runs great... My oil filter has bumps and a little rust, idk if its coming from thier or what.. If I just need to change oil and filter then what kind of oil and filter should I buy.. the car only has 79,000 miles on it...
