>> 1 quart per 1000 miles is the industry norm.
 
That's surprising, at least to me.
 
My '07 with 64k miles burns NO oil, which is great, since I use expensive Mobil 1 (0W-30).

I think what juice meant was that burning up to 1 qt per 1000 miles is an accepted tolerance in the industry. Anything less than that is acceptable.

I change my own also and use Castrol Syntethic blend 5w-30 and normal dring in the city it does'nt lost any, the minute I go on the intersate and in the mountains, I lose about 1-2 qts.

Correct.
 
Lately none of my engines burns any noticeable levels of oil, knock on wood.
 
My 1995 Mazda 626 did, a little. Still less than a quart between oil changes, though.

There is a separate coil for each cylinder. My 2006 Tribeca is currently in the shop having one of them replaced as it was misfiring and after a month of on and off misfiring it actually burned out while I was on my way to the mechanic to replace it. I thought bad gas as well, but I always use Hi-Test (93) and have used different gas stations. When I first had the misfiring I also used a gas treatment. It seemed to work but the issue came back again. Ignition coil ran me about 160 installed.

6 coils, really?
 
My 4 cylinder Forester had just one single ignition coil.
 
I replaced it ($80) when chipmunks chewed up the wiring around it.

Yeah 6 coils. I just confirmed it today with the mechanic. Each cylinder had its own and one of them (coil for cylinder 2) burned up which in-turn blew a safety fuse that controlled cylinders 2,4 and 6. The car wouldnt start at all. I was told that the car needs at least 2 of the 4 cylinders to start. All said and done, its going to cost me $240 to replace the coil that burned up and to replace the fuse that blew. Im going to pick it up tomorrow. Ill let everyone know how it runs.

More manufacturers are changing from a single coil and going to one for each plug. It eliminates the distributor and improves ignition performance.

#96 of 97 hp upgrade for 2006 tribeca by mtsubies

since the 2008 tribeca has increased horsepower than the 2006-2007, can you change the ECM on the older units to a 2008 ECM and pick up the increased hp since it is using the 2008 fuel programming?

The engine is very different - it went from 3.0l to 3.6l, longer stroke, dog-leg piston shafts, etc. I'd guess it would not run at all.
