Old car, new car, same oil rack.
There isn't a cheaper shelf for older motors.
Every engine has a specification it was built to run on, and that doesn't change with the value of the car. Nine miles or a hundred and forty thousand, the spec gets confirmed against your reg and the right Castrol oil goes in.
