Looking at the description of the "A" and "B" schedule in my owners manual, I decided my current driving habits most closely relate to the A schedule. I currently have 11,000 miles on my truck. When I brought my truck into my 5 Start dealer the service tech asked if I had changed my oil before this interval. I said no I'm following the "A" schedule which states 15,000 for the first oil change. The service tech proceeded to tell me that the "A" schedule is for vehicles that only travel highway miles in 70 degree weather? He went on to state that it states that in the owners manual and proceeded to read me the conditions for the "B" schedule. I then asked if they would send an oil sample out for analysis and he said it's too expensive and he hasn't done that in about four years. I gave up at this point and just had them service the vehicle, changing the oil, oil filter, lubing the tie rods, rotating the tires and draining the differentials and filling with synthetic. I chose this mileage to have the service because it is a compromise between the "A" and "B" schedule. I don't feel I have done any damage to my vehicle.
I guess I'm soliciting opinions as to whether the "B" schedule should be followed if the vehicle isn't used as described by that schedule? Basically at this point it is just a passenger vehicle.
