Need to change my oil, my roller rockers make a little noise and I got wondering what everyone else runs? I believe 5w-30 is what is recomended.
10w30 and a motorcraft filter. never had a problem. will NEVER run a fram
I no of a test that was done and castol GTX came out the worst. my friend recently freshened up his engine(honda) and it has 280,000 miles on it. when we tooks the pan off and valve cover every thing looked brand new nice and clean no crud built up. he uses halvoline and runs it in all his race cars and swears by it...halvoline is just advanced autozone brand. I have also seen a handful of cars from people switching from non-synthetic to synthetic and having issues, then they switch back and problems go away.Just Castrol 5w-30, $11 for 5 qt's at wally world, along with a motorcraft filter. I change oil every 2500 miles, so synthetic isn't worth my money.
some cars are indeed picky, my lexus sc400, does not like anything other than mobil 10w40, and 91 octane.... but my wife loves the darned thing.....
the advice in this thread topped out right here, fram filters are junk. if your spending 7+ bucks a quart for oil then pony up for a good filter.
