junnie, you move all over the place trying not to look like a fumb duck. but
you always end up clearly showing everyone here that you really didn't
understand the question in the start and clearly don't understand the question
in the end. Are you as dumb as jeffies?

let me explain it to you in simple terms, junnie. use multi-grade oil in your
engine. It is the oil made by oil companies for your engine. It is the oil
the designers of your engine intend you use in your engine. your engine will
last longer, junnie if you use multi-grade oil in it.

junnie, after reading your meandering below, I ask again:

why is it you think "viscosity" is in any particular way different from
"pumpability"?


Please read for content....

Viscosity is resistance to flow and, therefore, is related to
pumpability.

The point that you have missed is that ... Mini-Rotary
------------------------- Viscometer ------------------------------- (MRV)
tests are used to determine the oil's
"W" grade and are, thus, not related to viscosity.

huh?


Jax,

I don't know what to tell you, here. You've either misinterpreted the
test or haven't read the specification. 10W is NOT, I repeat, NOT a 10
weight oil. It is not a relationship of viscosity vs pumpability. It
is merely shear strength.

The only thing I can do is refer you to ASTM D-2602 and/or D-5293, for
THAT is the definition of what xxW means with respect to oil
specification.

One point I might be able to guide you on is that multi-vis oil is, by
definition, Non-Newtonian....
