Just picked up an 05 6s v6 5mt. Great car, handles well. It's been amazingly reliable, great on fuel and tons of power. 2 weeks ago it started consuming oil, or really, I noticed it was consuming oil. I'm low 1.5 quarts. I do lots of city driving and maybe up to 45 on the way home. My fuel mileage is also terrible. I don't know the actual number but I'm only getting 60 miles per quarter tank of fuel. Proper alignment, good bearings and CV joints, just did coils and plugs and new filter and oil change. Oh and less then 6 month old tires. I'm was BMW guy, also dealing with oil consumption on one of their engines as well. I've read about the pcv being bad, bought a new one but haven't installed it yet. Any idea how much these engines cost used and how much to rebuild one or if it's even worth keeping it.
