Title pretty much says it all. I've had my '16 for 16 months and almost 40k miles. I have a long 57 mile one way commute and can slow charge at work. I'm sitting at about 73% lifetime on electric. It finally started screaming at me about changing it when the oil quality hit 5% last week so I changed the oil this past weekend. That was about the most painless oil change I've ever done on a vehicle. Didn't spill a drop from the drain or the filter. Nice design Chevy. I also rotated the tires and just gave everything under the car and hood a good once over, as I have a 700 mile road trip coming up this weekend. Everything looks great. Man I love this car.
