Can anyone help with my oil struggle ? I have recently purchased some Mobil 1 15w-50 with every intention to change the oil on my 426 '01 this week. Unfortunately the bottle of Mobil 1 I have is labelled as 15w-50, Fully Synthetic Engine Oil, SJ/CF (For Gasoline and Diesal Engines). My owners manual for the bike advises engine oil with an API of SH or higher - so I'm fine there , but it also states that oils with CD or higher should not be used. Any ideas ?
