So I go to get some oil for my bike as I've worked out she is a little low (after finding out where the viewing hole is and getting some to hold the bike up) and I've bought some Castrol Power 1 4T 10w-40. Had a look in the manual and whilst 10w-40 is fine the API should be SE, SF, SG or higher and as this is SJ, I presumed this will be fine.
I had a quick look online as I know nothing about API ratings and apparently I shouldn't be using SJ and now I'm just confused.
What are peoples recommendations as to the oil I should be using?
Cheers
