The 2008 gs350 takes 6.9 quarts of mobil 1 or valvaline full synthetic 5w30 and to do it yourself with a quality oil filter cost about $42 worth of oil if you buy 2 5 quart jugs at a time and $8 For a fram 20k mile full synthetic filter. So about $50 to yourself if you already have the jack and jackstands, oil catcher, socket wrench set and 64mm oil filter removal cup.. Which are all tools every man should have..lol
