    i have ran mobile 1 high milage 5w-30 since i have got this pickup and lately it has been burning lots of oil (engine has 283k on it) I'm guessing the engine is just really worn out. but would running 10w30 make in not burn as much oil?

    If it hasn't been replaced in the last few years just replace it.

    Yeah, cheap and easy to replace. Driver's side, rear top of valve cover. Agree fully, if it hasn't been changed out, just do it.

    05 wont have a pcv valve....wtf are u guys smoking? the valve cover is the "valve." The fix is to replace the valve cover....easy and cheap.

    10/30 wont stop the oil consumption once ur up to temp. Step up to 10/40 if you want a lil thicker oil.

    Hows the oil pressure with a fresh oil change?

    It's still a pcv valve it just requires the whole valve cover to be replaced

    Yeah, a 40w would work. Many commercial fleets operating will put the same diesel oil they have in bulk for their large trucks into the gasser pickups they have and don't have any problem.

    A 5w30 and a 10w30 are the same thing. Just the 5w30 has a lower cold flow rating. But they are both 30w oils. You have to move up to a 40w to get a higher viscosity.
