tom, i can tell you for SURE you wont be getting NEAR as cold as me. i run 10-40 in my rambler motors. ya, i the winter, i go lighter 10-30 in the winter sometimes. but, i dont think you get -25* F. mine work just fine. even when i had 10-40 Quaker state in rosie, and didnt get a chance to get it out before it got below 0 this fall. make a 2nd oil job hack for me, and send me pics of what you needed to do to the block. ill let you know next winter if it works.
