Thanks for your response
Oil filter on my 2017 DGI +4 FO-MO-CO AA6E-6717AA Which I can't locate one
A friends 2016 DGI +4 Also has a FO-MO-CO AA6E-6717AA filter.
My 2006 Anniversary 1800 Duratec filter is a FO-MO-CO AA6E-6714AA Which I believe is correct.
I would like to know the differences between the two filters. It was suggested to me AA6E-6717AA Might have a none return valve to stop oil draining
From top end of engine. +4 DGI Engines rev on first Start up.?
