Thanks, bobs, for the welcome and the info. I see now that the FSS gauges your driving style and either adds or subtracts miles before the next oil change/inspection. What had me off was the other scheduled events like fuel filter, air filter, torque the steering locknuts, etc. The chart had them falling at a certain mileage and on an A or B check. How it works is if the event falls due for mileage just do it no matter what check you are on.
