As oil pump works from crankshaft movement and oil pressure drops everytime you stop the car, it is not reccommended to use this system. As oil pressure is low, crank bearings and other moving parts loose their protective oil "sheet" (because oil pump does not hold pressure) and result is increased friction every time you start engine again (until oil pressure is up again). This yet again should ruin engine (Yes, I know this is very very little). If I am terribly wrong then, please educate me!
If I am right, then could someone please tell me, how to disable this?
