I think that is a great article.
I think if you look at everything as a % most tips will apply.

I liked the part of for each 10'F lower temperature, wind resistance increases by 2%. Me at 0'F is 14% more wind resistance than someone in say, Jupiter Florida with 70'F. That's not counting the fact that the oil is colder, engine is colder, batteries are colder, winter fuel.... etc....
I also liked the fact the bald tires get better MPG than new ones!
