Sounds like you're experiencing nothing more than cold weather acting on
your lubes. I had a friend in high school that went to work on the Alaskan
pipe line & brought back stories about rolling 30w in a ball between his
finger & thumb. Of course, once it gets warm, all feels normal. Get a
block heater or dipstick heater to keep the engine from having to work so
hard on startup & to get oil flowing faster (don't want to starve those
critical bearing surfaces).
