If you don't drive alot, then go by months. if its been 3 months since an oil change, change it even if your not to the mileage.bigjcvegas wrote:Well i took the cube into nissan cause the service light came on,turns out it was a bad bypass valve,they also replaced the rear door handles,and i also had them change the oil,so they would quit calling me every week saying its been over 6 months since i purchased the vehicle,i only have 1162 miles on it,..maybe i need to drive it more.
