Leaks are problematical. They rarely slow down or stop unless the fluid that is leaking is all gone (HD motorcycles) :whoops:
If you are vigilant and don't care about the mess in the driveway and the condition of your undercarriage, you could potentially go a great distance.
I would not operate the vehicle, if it were mine, in remote areas. A sudden failure of the remaining sealing properties of the ailing components would be very disappointing.
