no, it takes 8.5 quarts. the original spec is wrong.
i only use 1 quart of synthetic oil per oil change. i use
dino for the remaining 7.5 quarts. i think pure synthetic
is overkill for this understressed engine.
if i lived in germany (or montana!) and frequently ran on the autobahn
i could justify using pure synthetic, but for speed limited WA, i don't
even see the oil temperature gauge creep up to 80 celsius. most of
the time it is just a whisker past stone cold!
consider the fact that the v8 has a huge oil cooler as well as a huge
sump capacity and the case to use pure synthetic is pretty weak.
i don't dispute that synthetic is better, just that its benefits on
the v8 will never be fully exploited under US driving conditions.
