    I started to go with Moble 1 BUT I read my owners manual.

    It turns out the only synthetic oil I can use in my motor is Castrol. Moble 1 does not meet the warranty requirments of my motors. So check your owners manuals and match them up with the right synthetic oil.

    Look in the owners manual and it will show you the "API certification mark and API service symbol" . That is also on the oil bottle.

    By checking that I found out Moble 1 does not meet the requirments for any of my motors since all require "SJ". Of the synthetic oils the only one I could find that met it was Castrol.

    I use regular HD oil. I don't do extended oil change intervals so synthetic isn't worth it to me.
