There's not a snowballs chance i'm going 10K on my oil.

 

Since moving to the hot air of Arizona last year, I got to admit:
My Z loses at least a quart of oil every couple months and yes, there is a bit of soot on the exausts.
I'm used to it now, but it shocked me the first time I figured out how low it was getting just a few weeks before a scheduled oil change.
