Materials used and amounts.

miscellaneous information: crush washers used, torque values for bolts, etc
I recently had the car in for an oil consumption test. At first the service manager started to give me grief about not having the oil changes done at the dealership. I handed him the print out of the service records I had recorded. Upon looking it over, he stated he had never seen an owner with as much intricate detail. No further problems.
I'm with you! I've been using a detailed spreadsheet going back to 1984. It includes everything I've ever done, the cost, who did the work if I didn't, the part numbers, date, etc. I doubt any dealership could dispute it.
