Delvac1 is not crap. I use it in 3 of my engines. (it is the same as
Mobil1). I put it in my Ford Lehman's with 3000 hours in them and it is
slowing the amount of oil consumption, smoke and oil sheen on the water. I
also noticed the temps went 5 degrees lower. I would certainly say that it
is a result of lower friction.

As I recall, the W prefix is a viscosity determination at a
set [low]
temperature ...
