[QUOTE="ShelbyGuy, post: 3862018, member: 10042"] everything you need to know is either in the owners manual or printed on the oil fill cap. :D at just under 52,000 miles i sent a sample of my oil to the lab (blackstone) the other day. i should get the results back today or tomorrow. i'll post them. on these engines its the machining of the internal passages that determines the weight of oil used. you may have noticed that all of the cars with the ford gt/00r/grand-am cup/new gt500 heads gets a 50 weight oil, but none of the 4.6 cars do. its not just for fuel economy. its because the engine has some seriously tight clearances. thats not to say they're sensitive to what oil you run, because they are not. you want a car thats sensitive to motor oil? try a pump düse volkswagen diesel. you can run 5w-30 or 10w-30 without damaging anything in the grand scheme of things. heck ive been known to run 0w-20 in the coldest periods of chicagoland winters. ive tried a few different weights and came back to 5w-20.
