Anybody try it, Mobil site says it can be used where 5-30 is used,
wont void warranty, has same hot temp lube properties and saves 2% on
gas, I am going to try it.

I ask myself "How can a 0w30 or 5w30 save gas compared with a 10w30
oil? Please follow my reasoning.

The 'w' stands for 'winter' and is a measure of how fast the oil flows
at cold temperatures. The second number is how fast it flows at
operating temperatures. The shear factor is closely related to the
flow rate so a 30w oil has a higher shear factor than a 10w oil,
meaning that the 30w oil will offer better lubrication and engine
protection at operating temperatures. An engine with better
lubrication will have less internal friction and use less fuel
overcoming it's internal friction.

If the above is true then it stands to reason that 0w30, 5w30, 10w30
and straight 30w oil would all give about the same lubrication at
engine operating temperatures. The differences would show up at a
cold start with 0w30 giving slightly better engine protection upon
start up than 10w30.

Since your engine only operates at reduced temperatures for a very
short period of time, the differences in fuel mileage between the
different oils should be barely noticeable. This assumes that you are
in the lower 48.

I'm not trying to be a smart-ass, I really would like to know if I'm
missing something here.

In switching from 10-30 M1 to 5-30 Mobil1 years ago my milage and
power went up noticably, I see what you are saying but it doesnt work
that way and I dont know why, Mobil is stating an improvement of 2%
and I believe it even though hot running film strength is about the
same as 5-30, Id say in reality at 170f its still thinner but film
strength is better.

What car? Toyota has a list (and Ray posted it here a few months ago) of
cars that can avail themselves of this oil.

Funny thing is, my Scion can, but a year or two older Camry with the same
motor can't...or is it that my Scion can't, but an '07 can?

Can it hurt to try?

Both of my cars use 5W-20. I did not like the idea of that at first, but
now I am OK with it. My truck uses 5W-30 and that took some getting used to
years ago.

If the manufacturer recommends against ut, I would take their advice.

Yeah, really. He didn't put an {OT} in the header to let us know he was
going to talk about something other than total bullshit.
