Hi I am Jesse I will be glad to try and help you. I looked up the poor quality message. It is usually set due to a problem in the system other than the fluid. Have you had codes checked? If not this is our first step. until we know exactly what code I stored in the system it will be almost impossible to diagnose your concern. do you have a way of getting them checked? autozone or advance autp parts can usually pull the code #'s for you for free.
Yes it doesn't have to be hard miles. Probably just a sensor going bad. unfortunately they can fail under even the best of conditions
