A system and process for optimizing vehicle service intervals for a plurality of vehicle service items begins with determination of a minimum service interval. The minimum service interval is set by the need to provide critical, though routine services such as engine oil changes and chassis lubrication. Multiple potential service intervals exist for at least one component, typically engine oil changes, based on different vehicle operating variables. Depending upon the character of vehicle use, one variable will control determination of the recommended interval for engine oil, which, after conversion to distance, is compared with the chassis lubrication to find the minimum service interval. Additional components/fluids are included for service based on operational variables selected to determine service intervals for these components.
