Bad rings, bad valve seals, bad PCV valve. I have seen some bad PCV valves allow high oil burning. Also is there a restirctor in the valve cover to vent.
I am using 0W-20 in my car and I dont loose any oil.
Well I never noticed it burning oil before the o2 induction manifold was installed... Then again, I never went on 800+ mile roadtrips one way.
Rings should be fine, valve seals are still stock. Only thing I didn't replace on the head
PCV valve is new, makes noise when you shake it, only blows one way. Catch can did fill up rather quickly, but not ALL the way.
The only reason I blamed it on the 30 weight was because of the LOOOONG drive where I kept the motor above 4Krpm in 5th gear. If I had chilled around 60mph or so, the drive would have taken HOURS longer. I wouldn't have been able to put up with it. I'm sure a thicker viscosity could have at least prolonged this another 30 minutes, in which case I would have been at the hotel already. In hindsight, I would have checked the oil twice as often as I did. I stopped in VA at my mom's house and added about a quart. I figured I was only 4 hours away from the hotel on a 12 hour trip, so I would make it just fine, then do an oil change when I got back. Didn't last...
