Change your battery every 3 years, seriously?
As for oil, just use synthetic as it does not congeal in cold weather.
How could any article giving advice about winter driving fail to mention how useless All Season tires are
in the typical Canadian winter? Unless you live in southern BC winter tires are essential.
All in all this is possibly the most vapid 'article' ever posted on this site.
Agree with other posters here. It sounds like the advice given here is either very outdated or just plain wrong. "Change batteries every three years?" Expensive and unnecessary. Batteries outlast three years easily. Run your engine to heat it? Most manufacturers do not recommend that as it may cause friction and it pollutes the environment. Change your oil to 5W... is there another kind? Flush your coolant annually? Seems like a waste of money and polluting to the environment if the coolant is still intact. "Consider" using windshield fluid with antifreeze? is there another kind in winter, and where in Canada does the temperature not reach 0 occasionally to say the least? Never mind the tire suggestion that has been dealt with aptly.
These tips are valid if you are driving a car in Florida in the 1950s. Seems like an article that is a cut-and-paste job from another website, and is also not authored. Why should anyone believe the "advice" given here?
