i switched it over to mobil1 10w-30 synthetic oil a week after i bought it. it had just under 120xxx on it when i bought it and now i'm only around 128xxx thanks to having a motorcycle to ride all summer. i'll just have to hit the autostart when i'm eating breakfast from now on i guess. i always try and ease into it with the short skirt on, it's better for her and gets me where i need to be.
