Maybe this the best time to use synthetic, when the engine is new and
doesn't dribble over the highway, or burn oil (although if it's going
to burn oil, SAE 0 will burn the most.)

And synthetic lasts longer, I forget how long, althought does one want
to do that with a new engine?

Well, if you have any engine trouble that might be covered by the
warranty, they might just check to see what viscosity you actually used.
If you didn't follow their requirements, there goes your warranty. Try
getting a flat fixed with the new TPMS systems.

The SAE rating isn't an actual viscosity; ergo, 0W-30 oil doesn't have
zero viscosity at the colder test temperature (0C iirc, 100C (~210F))
for the higher.

There's a chart of a range of performance conditions by which the
shorthand rating is determined for any given oil. Roughly, at least
originally, the lower rating was roughly the "pour point" in C; that has
become more refined and includes things like max cranking power. The
actual viscosity part of the test is still performed at 100C but is a
test for the minimum time (that is, the oil can't run at a lower rate
than that specified as the grade standard) as opposed to a min/max time
range for the high temp rating.

Use of pour point depressant additives can make any oil base perform to
the tests; what is chosen to be used is a combination of design
parameters as well as cost. Adding more additives raises cost as well
as can shorten life as additives wear out during use.

If they make oil that is SAE 0, what is the viscosity of water?

Depends on temperature

32F 1.79

60F 1.129

70F 0.982

200F 0.305
