As I understand Acura recommends that an oil change occur either based upon their computer algorithm or one year, which ever occurs first. My car was sold as new after sitting for about 1 1/4 years. The start date for the oil change began with the car's in service date. My car's computer says that the oil is still at 90% but the in service date is quickly approaching. I will probably change the oil at the in service date to insure compliance. The other maintenance Item I am thinking about is flushing the brake fluid. Has anyone out there done that? It is recommended at three years. In this particular instance just sitting around would allow for moisture. So I am thinking that flushing the system makes good sense. Is there anything else I should contemplate? The car has 5700 miles. I have driven it 1000 miles over the last two months. What about flushing out the radiator? The car runs perfect. This is the greatest driving car I have ever owned. I already removed the engine K&N filters and went back to the OEM paper filters.
