So then "a" 4.3 is in the lineup, but "the" 4.3 is no longer with us
I have a 4.3. But it's a V6!
It is also from Chevy.
Push-rod beastlyness. That engine LOVES to make power.
(Also: My 4.3 V6 WAS based on the old 5.7.)
What? The new 4.3 is also a v6.
I think what he meant was this was designed from the ground up as a V6, not a V8 with 2 cylinders chopped off.

I don't see why not, if that is what GM says. I personally hate to run anything that light if I maybe towing.
Lots of Fords running 5w-20 and towing. I don't hear stories of those blowing up.
Ford has been using 20 grade oil since the late 90s? Almost 20 years? NEVER hear of any oil related failures on the 4.6/5.4/6.8
