Just hit 220k and got an oil change and tire rotation. I have a 2001 Honda Insight. I changed swapped the cvt fluid @191k when I got the car (didn’t flush). I replaced the hybrid battery in it over a year ago and it’s been flawless. When I requested a cvt fluid change they told me not to as it would pretty much destroy the cvt at this mileage. Any recommendations? Leave it as it until she dies? Or do the swap anyway on my own?
