How do you set the mileage for a CD 1oo to achieve maximum mileage?

120 mph

Don't know if there is a maximum, if it's taken care of from the beginning, who knows. Generally they will get 200,000 miles without major stuff going wrong.

I have 255,000 on a 1987 Nissan 300zx and still running strong. As long as you maintain the car and change the oil evry 3000 mi it should last a long time.

I think around 300,000 miles

keep it well maintenance like fluid change, timing belt, spark plugs, fuel filter, rotor cap etc. and you can see it go over 500k easily or forever lol keep it well maintenance like fluid change,...
