oil change. How many miles, at 15% oil indicator, before need change ?
My RDX says 15% before oil change necessary: need to drive 1400 miles; can
I make it home before required oil change ?
I would change the oil before the trip. At a minimum you should check the oil level and top it off before driving any further. In the future I recommend changing oil every 5,000 miles instead of using the reminder system.
