You can order the OAI sample kits through the AMSOIL or the OAI websites - $19 each postage paid. I do a filter change and analysis every 3K and oil change every 6k. Theoretically, you could leave the oil in indefinitely and test it regularly until they tell you it's time to change. If a serious problem is detected they will call immediately and inform you. Check out the sample report at the URL below.
