The days of manually checking your oil with a dipstick may soon be over. Debuting at this year's SEMA show, Intellistick's Oil Condition Monitor uses a series of sensors to constantly monitor the electrical properties--and therefore the condition--of your car's oil.
This information is then sent to the driver's PDA using (what else?) Bluetooth, meaning that, without even popping the hood, drivers can know exactly when to change their oil. Check out Brian Cooley's video of the device, complete with a lesson in petrochemical decomposition.
