OK guys...this may seem like a very stupid question, but need to know how much oil a '98 Mustang V6 is supposed to hold. My girlfriend hasn't changed her oil by herself(her dad does it), and I'm gonna do it. My 5.0 holds 5 quarts, and I believe that her car holds something near that...all I know is that there is no time to lose, I'm changing the oil today for her because she's like 4000 miles over due....any help is greatly appreciated.Thanks.
