I am changing my oil for the first time in my 02 3.4 V6. The exact oil capacity is confusing me. The manual says 5.5 qts with filter change. This brings the level to the add mark on the dipstick. The manual also says the difference between the full and add mark on the dipstick is 1.3 qts. Together that is 6.8 qts. The dealer tells me the capacity is 6.5 qts. What is right? Thanks for a reply.
