I am getting ready to do my first oil change on my new truck. I looked in my manual and saw it said I would need 8 quarts of oil. My dad just bought the same truck and his manual says it takes 10.5 quarts of oil. How much oil do you use? We did just notice that my book says it is the third edition, and my dad's is the 4th edition. My oil quantity is listed on page 202. my dad's is listed on page 209. Thanks for the input.
