I just did the first oil and filter change and found this to be the easiest oil/filter change on any vehicle, except a Suzuki SV650, that I've ever done. The filter and plug come off easily, were accessible by just lying on the ground without having to either jack up or raise the car on ramps. There was no muss, no fuss - used the Mitsu filter, and 3.3 litres Mobil 5W-40 ESP 'M' oil. It's really too bad that the OCI'S are so far apart with the job being so easy.
The only issue was to torque the drain plug - solved by using a long handle 'click' 50-250 LB FT torque wrench. The spec of 65 NM is just shy of 50 LB FT so this worked out just fine. Actually the same will be used to remove the plug next time making that task easier as well.
By the way, I've now had three vehicles that used filters made by Tokyo Roki. They make OEM filters for many Japanese engines, car and motorcycle. After taking them apart and comparing them to others, I wouldn't hesitate to use them whenever possible. If your dealer stocks the Mitsu filter then use it. If not, then get one that cross references, such as the Yamaha filter.
