Oil change

Doing my fist ever oil change this weekend and was wondering 2 things. Should I get an oil filter from a Yamaha dealer or will one from Supercheap Auto be ok?

Secondly, the previous owner was using 10w-40 but I checked in the owners manual and it Ai ply says API service "SE", "SF" type or equivalent. I have no idea what these are? I've googled them and they look to be the quality of the oil? Could I not use better oil like SJ or SN?

Thanks

Oil change

I'm going to be doing my first oil change today and got a few questions.

I've recently got a Yamaha Scorpio and also its service manual, but looking up how to do an oil change in the book, I can't find out what size O-ring I need for the oil drain bolt. I guess I could take it off and while it's draining go to a parts store, but surely I can find the size out before taking it off?

Also, with the oil filter replacement, it says to clean with solvent. Is kerosene ok to use to clean? Do. Just buy a new oil filter or clean the old one?

Thanks a lot
