Doing an oil change on a buddy's 08' Ranger (4.0 SOHC) and hes reported some valve rattle and some startup noise with "whatever midas is putting in"
he wants to stay with 5w30 but doesn't know much about oil.
took a look inside his valve cover, hes got some varnish (At ~130k miles) but nothing awful. Whats a good "Thick 30" that might help with the rattle he's hearing.
I was also thinking about throwing some Motorcraft in there or maybe PP to help with the varnish.
Any ideas on a "thick" 30?
