I had the oil changed on my 03 SSR after 650 miles (1 month of ownership) by the dealership more so because of the amount of time the oil had been in the engine. My 03 SSR was was sitting on the sales lot until I purchased it in 6/2004. Even though the DIC stated I had 90% left on my oil, the amount of time was not being factored into the DIC's calculation. Keep that in mind if you're buying an 03/04 SSR that's been on the lot for a while.
