Vehicle info needed

[biggie360]

Hey there. I was recently employed as an apprentice drivetrain technician, but due to the failing economy the shop closed down. I managed to get a job at Walmart as an oil changer. I would like to become faster and more efficient at my job, but most of our vehicle information is wrong. for instance, 2007 Ford Mustand GT 4.6L V8's do NOT take 2.5 Qts of oil, but our computer system says that they do... I was hoping that someone could point me in the direction of a site that would have information on most if not all makes/models/years/engine sizes. I'm looking for the oil filter number, oil capacity, and drain plug torque specifications. any help would be greatly appreciated.
