well, first day was today. things went really well, all i really do is unscrew drain plugs, let oil drain, replace the drain plug, and put a new filter on, and thats it. i was there from 8 am to 2 pm today and 3 of us did like 20-30 cars, and they said that was a busy day for them. still seemed like i spent a lot of time standing around and doing nothing though.
