So,

I needed to take a road trip to Detroit from Toronto Canada. About a 6 hr drive. I changed my oil before I left, and when I got home i noticed a week later my car wasnt driving very well... im like this is odd... i took it in for an oil change.. i have no idea why.. just a thought, and sure enough I had no oil in my Z... nothing...

whats up with that??? now im putting in more oil per change..
