It takes less than that to do it properly on a honda at Jiffy-Lube. Six minutes is plenty of time. Eight maybe Ten on a BMW or anything else with a cartridge style filter. If you take it to a tire place it takes a bit more time, they have scissor style racks that the car has to be positioned on and lifted carefully rather than drive-over pits like the quicklubes. Also means only one person can do the oil change rather than a team of 3-5. Regardless, for some people it's just "too much money" and "too inconvenient." I personally don't understand how even 60-70 every two or three months is too much money for people who drive a gas tank a week out of an SUV.
