M1 0w20 & 0w30 oil bottle states something to the effect : " Fine / safe for all vehicles which stipulate 5w20 / 5w30 oil weights" . Is there ever an instance or situation when it is not fine / safe to use a 0w20 / 0w30 oil in place of 5w20 or 5w30 the vehicle manual or oil fill cap recommends ?

I'm not aware of any such instance or situation.

The note on the label is there for people scared to run anything "0w" because they think it flows like water.

I all a car calls for is a SL/SM/SN spec 5-30 I doubt it. I base this on my assumption that the 0-x oils have the same resistance to shear as a 5-x oil, which may or not be a safe one. That would be my only concern.

Other specs, like manufacturer specific specs, may make those oils not suitable for other reasons.

For a number of reasons 0W-XX oils are superior formulations to their 5W-XX counterparts. So the answer to your question is no.

Anything with a '0' as the first # has to be a full synth.
That has some inherent advantages right there.
And with better cold flow, who would not want a 0-X? [except for cost!]]

So sure... the 0-Xs are never a downgrade, and always suitable - they often have advantages in the extreme cold/hot.

Shell makes a 0w-30 synthetic blend as well (Rotella T line), if I'm not mistaken.

And Petro-Canada Duron 0W-30 and the current COP made Honda 0W-20 comes in both full syn and syn blend versions, BUT mechtech2's
point is well taken.

Thanks for the replies ...besides M1 0w20 & 0w30 which I believe are sold at Walmart , does Penzoil have a readily available 0w20 & 0w30 ? If so , how does it stack up against M1 (i.e. availability , price , performance) ?

Pennzoil Platinum 0w-20 is listed on Pennzoil's website. Not sure how readily available it is.

Pennzoil does make a 0W-20, it's good, lighter than M1 0W-20 and I prefer it to M1.
They don't 0W-30.

Any other 0w20 or 0w30 oils come to mind you have or would consider using (Valvoline , Castrol , etc.)

I use Mobil 1 0W30 in my 05 Prius. I'd like to use their 0W20 but am not sure if it is approved by Toyota just yet.

The Toyota Brand 0W-20 has been spec'd for the Prius starting with the 2004 MY. Here's the list:

It has recently become readily available up here in Canada, as both Canadian Tire and Walmart carry it now.
