    Re: oil for a 115 4 stroke (X17xpress)

    I use Royal Purple syn. oil in my 2004 F150 with no problems. The only syn. FC-W for your 2007 that I know of is Amsoil (must use a FC-W to maintain warranty.) My engine took 50-75 hours to break-in. Unless you put a lot of hours on your engine, I would do the 10 hour oil change with dino oil and go to syn. after the first year.
