This keeps coming up:
I e-mailed Toyota Motor Sales, U.S.A., Inc. RE the continued statement that the Generation 2 Prius is back specced to xW/20 engine oil.
I included the two commonly posted charts related to this:
WARNING direct link to PDF Toyota-Engine-Oil-Guide.pdf
And:
Toyota Oil Applications - The one with all the dots in THIS post.
Note the first one is hosted on http://gp1cc.com which appears to be a large dealer group that has several Toyota and Lexus dealers.
I was told:

When I specifically questioned the validity of the two charts I was told:

The Toyota Oil Applications document was not produced by Toyota Motor Sales, U.S.A., and may be a document that was produced by a different distributor of Toyota.
The Toyota Engine Oil Guide is the first one and The Toyota Oil Applications is the second one.
Additionally as I previously posted:

NOTE :
^ The recommended viscosity grade for this oil differs according to vehicle model. Use the recommended grade specified on the oil filler cap or in the Repair Manual or Owner's Manual for each vehicle.
^ For Prius vehicles, refer to TSB No. EGO5O-04, "Engine Oil Specifications."

Ensure that the correct engine oil viscosity is used in the engine with the correct fill level
quantity as described in the Owner’s Manual:
Engine Oil Quantity, with filter,
qt.(L, Imp. qt.):
3.9 (3.7, 3.3)
Recommended Viscosity: SAE 5W–30
Engine Oil Grade: API grade SL “Energy–Conserving” OR
ILSAC GF–4
So unless someone can come up with a TSB that supersedes EGO5O-04 I maintain that a 2007 Prius is NOT back specced to 0W(or5W)-20
