Here you go, I added miles to the Scheduled Maintenance. As noted above, our cars have built in maintenance minders that will pop up and tell us to do something. I am really anal about maintenance and like to be ahead of the curve. Also notice in the fine print it says to change the oil if a year has passed even if not driven. Then it says change the filter every two years even if not driven. My take is changing the oil takes most of the work and the filter is relatively easy. So always change the filter when changing the oil. While our engine has not been shown to have problems with oil becoming sludgy after awhile, I can recall that Toyota and Lexus specifically had a lot of 3 liter engine failures due to prolonged oil change intervals. The engine heads were eventually reworked but not until there were a shit load of failed engines. There was never a recall but Lexus fixed those engines out of good will for years. This whole episode resulted in their changing oil changes to not only miles but time based. So even if you don't drive your car for the year, it is recommended that you change the oil. My only dilemma is that I do not have a lift at home as I would enjoy doing the process myself. Putting the car up on jacks is again not too much fun given I like to look things over and laying on my back is not my preference.
