The oil change system includes an evacuation system, a refill system, one or more sensors and a control circuit. The evacuation system includes a first quick connect fitting configured to mate with a quick connect valve of a vehicle. The refill system includes a second quick connect fitting configured to mate with the quick connect valve of the vehicle. The control circuit is coupled to the evacuation system, the refill system and the one or more sensors, and is configured to automatically identify the vehicle, determine a type, a viscosity and a volume of oil associated with the vehicle and control a volume of new oil added to the vehicle. ## Claims ### Claim 1 An oil change system, comprising: an evacuation system comprising a first quick connect fitting configured to mate with a quick connect valve of a vehicle; a refill system comprising a second quick connect fitting configured to mate with the quick connect valve of the vehicle; one or more sensors; and a control circuit coupled to the evacuation system, the refill system and the one or more sensors, wherein the control circuit is configured to automatically: identify the vehicle; determine a type, a viscosity and a volume of oil associated with the vehicle; and control a volume of new oil added to the vehicle. ### Claim 2 (depends on 1) The oil change system of claim 1, wherein the evacuation system further comprises at least one of the following: a hose coupled to the first quick connect fitting; a valve coupled to the first quick connect fitting; and a pump coupled to the first quick connect fitting. ### Claim 3 (depends on 1) The oil change system of claim 1, wherein the refill system further comprises at least one of the following: a hose coupled to the second quick connect fitting; a valve coupled to the second quick connect fitting; and a pump coupled to the second quick connect fitting. ### Claim 4 (depends on 1) The oil change system of claim 1, wherein a first one of the one or more sensors is configured to sense whether the first quick connect fitting is connected to the quick connect valve of the vehicle. ### Claim 5 (depends on 4) The oil change system of claim 4, wherein a second one of the one or more sensors is configured to sense whether the second quick connect fitting is connected to the quick connect valve of the vehicle. ### Claim 6 (depends on 1) The oil change system of claim 1, wherein the control circuit comprises: a processing circuit; a memory circuit; and a wireless communication module. ### Claim 7 (depends on 1) The oil change system of claim 1, wherein the control circuit is further configured to automatically identify the vehicle based on a signal communicated from the vehicle and received by the control circuit. ### Claim 8 (depends on 1) The oil change system of claim 1, wherein the control circuit is further configured to automatically determine, based on the identified vehicle, the type, the viscosity and the volume of the oil associated with the vehicle. ### Claim 9 (depends on 1) The oil change system of claim 1, further comprising a purge system coupled to the control circuit. ### Claim 10 (depends on 9) The oil change system of claim 9, further comprising a filter cleansing system coupled to the control circuit. ### Claim 11 (depends on 1) The oil change system of claim 1, further comprising a user interface coupled to the control circuit, wherein the user interface comprises at least one of the following: a display; a keypad; a scanner; a card reader; and a printer. ### Claim 12 (depends on 1) The system of claim 1, further comprising a tool cabinet coupled to the control circuit, wherein the tool cabinet houses at least one filter wrench. ### Claim 13 (depends on 1) The system of claim 1, further comprising a filter depository coupled to the control circuit, wherein the filter depository is configured to receive an oil filter removed from the vehicle. ### Claim 14 (depends on 1) The system of claim 1, further comprising a filter dispenser coupled to the control circuit, wherein the filter dispenser is configured to dispense a new oil filter for the vehicle. ### Claim 15 A method of performing an oil change service, the method comprising: utilizing a control circuit to automatically identify a vehicle; evacuating oil from an engine of the vehicle via a first quick connect fitting configured to mate with a quick connect valve of a vehicle; utilizing the control circuit to automatically determine a type, a viscosity and a volume of new oil; and controlling a volume of the new oil added to the engine of the vehicle via a second quick connect fitting configured to mate with the quick connect valve of the vehicle. ### Claim 16 (depends on 15) The method of claim 15, wherein utilizing the control circuit to automatically identify the vehicle comprises automatically identifying the vehicle based on a signal communicated from the vehicle and received by the control circuit. ### Claim 17 (depends on 15) The method of claim 15, further comprising utilizing the control circuit to automatically determine, based on the identified vehicle, the type, the viscosity and the volume of the new oil. ### Claim 18 (depends on 15) The method of claim 15, further comprising introducing a purging agent to an oil filter of the vehicle. ### Claim 19 (depends on 18) The method of claim 18, further comprising introducing a cleansing fluid to the oil filter of the vehicle. ### Claim 20 (depends on 15) The method of claim 15, further comprising replacing an oil filter of the vehicle.
