How are your parts departments figuring the average quarts of oil per change? We have 5 car brands on our campus. Originally, let's say 5 years ago, I divided the number of quarts sold for a year into the number of transactions for a year. That gave me an average of quarts sold per car. I created a part number that represented that cost and quantity. Obviously by using that part number over the years I have lost the ability to redue that calculation and must rely on the shop foremans best guess at the average number of quarts used per car.
Thanks for any input!
