I think its time for some Italian tuning.

 

I didn't think the plugs would have a darn thing to do with oil consumption. I'll wait and see what the dealer does beyond the plug and wire change. I've tried an Italian tuneup, but it didn't help!

 

Of course the plugs could affect power requiring more throttle to deliver the required power, which would in turn increase oil consumption. Just a thought.

 

That's a valid point.

 

Yes, but the car seems to basically runs fine, just a very rough idle, especially when fully warmed up. I have driven 400 miles and it's down at least a 1/2 quart already. It's being very consistent in its high oil usage. I have to believe it's something with the oil injection. I'm not mashing down the throttle to get the car to go, so I don't think it could be affecting oil consumption that much. I hope they figure it out. If not, I'm on my 3rd dealer (the first one ripped me off for $300 when my car flooded, the 2nd went out of business) and out of options.
