    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.
