Our Volt just went over 30K solar powered miles. With 1,400 gallons of gas saved under two years.
Only maintenance required was a couple tire rotations and one oil change.
I do the tire rotations and the oil change. I run mobile 1 one with AC Delco OEM filter it was about $32 for the oil change. Not bad for 36k miles.
