If anybody has something bad to say about Mobil 1 0W-40 European Car Formula, please let me know. About to bite the bullet. Read everything everyone has to say. Yes, Amsoil is held in high regard. Some go purple. Others go elsewhere. Some swear by 5W-50, or 10W-40, or 0W-40, or 0W-50, or 20W-50. Seems like to deciding factor is how hard you ride and your climate. I'm not too harsh a rider and Mobil 1 0W-40 euro seems to be the ticket. And a six pack of quarts at Costco is $36.99!!! Speak now or forever hold your piece(s of my busted motor).
