[fixer]

hey i didn't mean to insult you but i'm an auto tech at an independent shop and i've seen what i described before, twice. seriously i was offering a suggestion, not a dig.
you said that the drain plug was loose?
if it was loose enough to drip, then 6,700 miles is plenty of time to loose 4 quarts.was it "finger tight?". by the way if you're in the valley we should hang sometime.
