A few days ago I replaced the stator cover on my 08 Busa. When I took the cover off a lot of oil poured out. I lost about 1.5 qt of oil. The oil in the bike was Motul 10w40 full synthetic and to top it off I put some Mobil1 10w40 full synthetic in it because i couldnt find motul anywhere. Is it safe? or should I change the oil?
