So here is my sad story of trying to do simple tasks without enough light. I was topping off fluids in the wee hours today in preparation for an upcoming road trip. Topped up the coolant rervoir, oil and was going to do the windshield cleaner tank too. When I got to the last one I inadvertantly poured about 1/2 pint of store-bought windshield cleaner into the power steering reservoir instead!!!!! I didn't realize my mistake until this morning when I noticed the spot of fluid on the garage floor. Upon close up inspection( in good lighting now ) my screw up was evident. I needed to use the car so drove it for about fifty miles with no apparent affect. I am going into the dealer tomorrow for a scheduled oil/filter change and will now have to include a flushing out of the power steering system as well. Stupid is what stupid does and boy was I stupid!!!
