I don't get it.
M1 5-40 is thicker than 10-40 all across the board, at any temp.

Exactly, it pours at -49 F, that's good enough for me where it never gets below 0. According to UOA's, Saab 4 cylinder turbos like mine love this oil. Don't get too caught up in the numbers game, you don't need the absolute perfect oil for your application. Good enough will do just fine.quote:

Maybe, take a look through the first 15 or so pages of this 1.4MB PDF document:quote:

You reproduce a chart and then say to ignore charts.quote:

As an example this is how Porsche deal with viscosity and the expected ambient range;
"Above -25C all Approved oils (0w-40 and 5w-40) may be considered
Below -25C all Approved oils (0w-40) with a 0w viscosity may be considered
Cayenne and Cayenne "S" BiTurbo MUST only use an Approved 0w-40 oil all year round"

Oh, now Doug, that is not very "honorary Elvish." You post here because you like us and we, at least some of us, are a fun bunch.quote:
