Oil exchange timing indicating apparatus for vehicles
First Claim
1. An oil exchange timing indicating apparatus for a vehicle, comprising:
- odometer means for integrating travel distances of the vehicle;
operation time integrator means for integrating operation times of an engine mounted on the vehicle;
oil exchange informing means for informing a user of exchange timing of oil; and
controlling means for starting, when either an integrated value of the travel distances or an integrated value of the operation times, based on signals from said odometer means and said operation time integrator means exceeds a preset value, said oil exchange informing means to inform the user of the exchange timing of oil.

Abstract
An oil exchange timing indicating apparatus for vehicles capable of informing a user of an exchange timing of oil on the basis of the degree of degradation of oil as quickly as possible. An oil exchange timing indicating apparatus includes an odometer for integrating vehicle travel distances, an operation time integrator for integrating operation times of an engine mounted on the vehicle, an oil exchange informing device for informing a user of an exchange timing of oil, and a controlling device for starting, when either an integrated value of the travel distances or an integrated value of the operation times, based on signals from the odometer and the operation time integrator exceeds a preset value, the oil exchange informing device to inform the user of the exchange timing of oil.

10. An oil exchange timing indicating apparatus for a vehicle, comprising:
-
an odometer for determining travel distances of a vehicle and for generating a travel distance signal; an operational timer determining the time of operation of an engine of a vehicle and for generating a time of operation signal; oil exchange indicator for informing a user of an exchange time for oil; and a controller for comparing at least one of a travel distance and a time of operation based on signals from said odometer and said time of operation as compared to a preset value for the travel distance and the time of operation, and for providing a signal to the oil exchange indicator inform the user of the exchange timing of oil. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
