Have you noticed a number and letter on a bottle of motor oil? The first number will let you know its cold weather viscosity, and the letter will tell you it’s viscosity in hot weather. Lower numbers will be less vicious in colder temperatures, so a motor oil with a low viscosity rating is suggested for use in cold weather.
